Methods

  Name Description
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 CompareTo(Boolean) Compares this instance to a specified Boolean object and returns an integer that indicates their relationship to one another.
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 CompareTo(Object) Compares this instance to a specified object and returns an integer that indicates their relationship to one another.
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 Equals(Boolean) Returns a value indicating whether this instance is equal to a specified Boolean object.
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 Equals(Object) Returns a value indicating whether this instance is equal to a specified object. (Overrides ValueType.Equals(Object).)
Protected methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 GetHashCode Returns the hash code for this instance. (Overrides ValueType.GetHashCode().)
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 GetType Gets the Type of the current instance. (Inherited from Object.)
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 GetTypeCode Returns the TypeCode for value type Boolean.
Protected methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public methodStatic memberSupported by Silverlight for Windows PhoneSupported by Xbox 360 Parse Converts the specified string representation of a logical value to its Boolean equivalent, or throws an exception if the string is not equivalent to the value of Boolean.TrueString or Boolean.FalseString.
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 ToString() Converts the value of this instance to its equivalent string representation (either "True" or "False"). (Overrides ValueType.ToString().)
Public methodSupported by Silverlight for Windows PhoneSupported by Xbox 360 ToString(IFormatProvider) Converts the value of this instance to its equivalent string representation (either "True" or "False").
Public methodStatic memberSupported by Silverlight for Windows PhoneSupported by Xbox 360 TryParse Tries to convert the specified string representation of a logical value to its Boolean equivalent. A return value indicates whether the conversion succeeded or failed.

Remarks

Instances of this type have values of either true or false.

This value type implements interfaces IConvertible, IComparable, and System.IComparable<T>. Use the Convert class for conversions instead of this type's explicit interface member implementation of IConvertible.

Thread Safety

All members of this type are thread safe. Members that appear to modify instance state actually return a new instance initialized with the new value. As with any other type, reading and writing to a shared variable that contains an instance of this type must be protected by a lock to guarantee thread safety.
