.png) | CompareTo(Boolean) | Compares this instance to a specified Boolean object and returns an integer that indicates their relationship to one another. |
|
| CompareTo(Object) | Compares this instance to a specified object and returns an integer that indicates their relationship to one another. |
|
| Equals(Boolean) | Returns a value indicating whether this instance is equal to a specified Boolean object. |
|
| Equals(Object) | Returns a value indicating whether this instance is equal to a specified object. (Overrides ValueTypeEquals(Object).) |
|
| GetHashCode | Returns the hash code for this instance. (Overrides ValueTypeGetHashCode.) |
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
| GetTypeCode | Returns the TypeCode for value type Boolean. |

| Parse | Converts the specified string representation of a logical value to its Boolean equivalent, or throws an exception if the string is not equal to the value of BooleanTrueString or BooleanFalseString. |
|
| ToString | Converts the value of this instance to its equivalent string representation (either "True" or "False"). (Overrides ValueTypeToString.) |
|
| ToString(IFormatProvider) | Converts the value of this instance to its equivalent string representation (either "True" or "False"). |
|
| 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. |
Fields

Platforms
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
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.
