1

Initializes a new instance of the class, using the specified debugging modes for the just-in-time (JIT) compiler.

A bitwise combination of the values specifying the debugging mode for the JIT compiler.

Specifies the debugging mode for the just-in-time (JIT) compiler.

Instructs the just-in-time (JIT) compiler to use its default behavior, which includes enabling optimizations, disabling Edit and Continue support, and using symbol store sequence points if present. In the .NET Framework version 2.0, JIT tracking information, the Microsoft intermediate language (MSIL) offset to the native-code offset within a method, is always generated.

Disable optimizations performed by the compiler to make your output file smaller, faster, and more efficient. Optimizations result in code rearrangement in the output file, which can make debugging difficult. Typically optimization should be disabled while debugging. In versions 2.0 or later, combine this value with Default (Default | DisableOptimizations) to enable JIT tracking and disable optimizations.

Enable edit and continue. Edit and continue enables you to make changes to your source code while your program is in break mode. The ability to edit and continue is compiler dependent.

Use the implicit MSIL sequence points, not the program database (PDB) sequence points. The symbolic information normally includes at least one Microsoft intermediate language (MSIL) offset for each source line. When the just-in-time (JIT) compiler is about to compile a method, it asks the profiling services for a list of MSIL offsets that should be preserved. These MSIL offsets are called sequence points.

In the .NET Framework version 2.0, JIT tracking information is always generated, and this flag has the same effect as with the exception of the property being false, which has no meaning in version 2.0.

Defines the formatting options that customize string parsing for some date and time parsing methods.

Date and time are returned as a Coordinated Universal Time (UTC). If the input string denotes a local time, through a time zone specifier or , the date and time are converted from the local time to UTC. If the input string denotes a UTC time, through a time zone specifier or , no conversion occurs. If the input string does not denote a local or UTC time, no conversion occurs and the resulting property is .

Extra white-space characters in the middle of the string must be ignored during parsing, except if they occur in the format patterns.

Leading white-space characters must be ignored during parsing, except if they occur in the format patterns.

Trailing white-space characters must be ignored during parsing, except if they occur in the format patterns.

Extra white-space characters anywhere in the string must be ignored during parsing, except if they occur in the format patterns. This value is a combination of the , , and values.

If no time zone is specified in the parsed string, the string is assumed to denote a local time.

If no time zone is specified in the parsed string, the string is assumed to denote a UTC.

If the parsed string contains only the time and not the date, the parsing methods assume the Gregorian date with year = 1, month = 1, and day = 1. If this value is not used, the current date is assumed.

Default formatting options must be used. This value represents the default style for the , , and methods.

The field of a date is preserved when a object is converted to a string using the "o" or "r" standard format specifier, and the string is then converted back to a object.

Determines the styles permitted in numeric string arguments that are passed to the Parse and TryParse methods of the integral and floating-point numeric types.

Indicates that the numeric string can contain a currency symbol. Valid currency symbols are determined by the property.

Indicates that the numeric string can have a decimal point. If the value includes the flag and the parsed string includes a currency symbol, the decimal separator character is determined by the property. Otherwise, the decimal separator character is determined by the property.

Indicates that the numeric string can be in exponential notation. The flag allows the parsed string to contain an exponent that begins with the "E" or "e" character and that is followed by an optional positive or negative sign and an integer. In other words, it successfully parses strings in the form nnnExx, nnnE+xx, and nnnE-xx. It does not allow a decimal separator or sign in the significand or mantissa; to allow these elements in the string to be parsed, use the and flags, or use a composite style that includes these individual flags.

Indicates that the numeric string represents a hexadecimal value. Valid hexadecimal values include the numeric digits 0-9 and the hexadecimal digits A-F and a-f. Strings that are parsed using this style cannot be prefixed with "0x" or "&h". A string that is parsed with the style will always be interpreted as a hexadecimal value. The only flags that can be combined with are and . The enumeration includes a composite style, , that consists of these three flags.

Indicates that the numeric string can have a leading sign. Valid leading sign characters are determined by the and properties.

Indicates that leading white-space characters can be present in the parsed string. Valid white-space characters have the Unicode values U+0009, U+000A, U+000B, U+000C, U+000D, and U+0020. Note that this is a subset of the characters for which the method returns true.

Indicates that the numeric string can have one pair of parentheses enclosing the number. The parentheses indicate that the string to be parsed represents a negative number.

Indicates that the numeric string can have group separators, such as symbols that separate hundreds from thousands. If the value includes the flag and the string to be parsed includes a currency symbol, the valid group separator character is determined by the property, and the number of digits in each group is determined by the property. Otherwise, the valid group separator character is determined by the property, and the number of digits in each group is determined by the property.

Indicates that the numeric string can have a trailing sign. Valid trailing sign characters are determined by the and properties.

Indicates that trailing white-space characters can be present in the parsed string. Valid white-space characters have the Unicode values U+0009, U+000A, U+000B, U+000C, U+000D, and U+0020. Note that this is a subset of the characters for which the method returns true.

Specifies how a instance synchronizes access among multiple threads.

Locks are used to ensure that only a single thread can initialize a instance in a thread-safe manner. If the initialization method (or the default constructor, if there is no initialization method) uses locks internally, deadlocks can occur. If you use a constructor that specifies an initialization method ( parameter), and if that initialization method throws an exception (or fails to handle an exception) the first time you call the property, then the exception is cached and thrown again on subsequent calls to the property. If you use a constructor that does not specify an initialization method, exceptions that are thrown by the default constructor for are not cached. In that case, a subsequent call to the property might successfully initialize the instance. If the initialization method recursively accesses the property of the instance, an is thrown.

The instance is not thread safe; if the instance is accessed from multiple threads, its behavior is undefined. Use this mode only when high performance is crucial and the instance is guaranteed never to be initialized from more than one thread. If you use a constructor that specifies an initialization method ( parameter), and if that initialization method throws an exception (or fails to handle an exception) the first time you call the property, then the exception is cached and thrown again on subsequent calls to the property. If you use a constructor that does not specify an initialization method, exceptions that are thrown by the default constructor for are not cached. In that case, a subsequent call to the property might successfully initialize the instance. If the initialization method recursively accesses the property of the instance, an is thrown.

When multiple threads try to initialize a instance simultaneously, all threads are allowed to run the initialization method (or the default constructor, if there is no initialization method). The first thread to complete initialization sets the value of the instance. That value is returned to any other threads that were simultaneously running the initialization method, unless the initialization method throws exceptions on those threads. Any instances of that were created by the competing threads are discarded. If the initialization method throws an exception on any thread, the exception is propagated out of the property on that thread. The exception is not cached. The value of the property remains false, and subsequent calls to the property, either by the thread where the exception was thrown or by other threads, cause the initialization method to run again. If the initialization method recursively accesses the property of the instance, no exception is thrown.
