Represents a Boolean value.

Assembly: mscorlib (in mscorlib.dll)

Syntax

Public Structure Boolean _
    Implements IComparable, IComparable(Of Boolean),  _
    IConvertible, IEquatable(Of Boolean)
public struct Boolean : IComparable, IComparable<bool>, 
    IConvertible, IEquatable<bool>

The Boolean type exposes the following members.

Methods

Name Description
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 ValueType..::.Equals(Object).)
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.)
GetHashCode Returns the hash code for this instance. (Overrides ValueType..::.GetHashCode()()().)
GetType Gets the Type of the current instance. (Inherited from Object.)
GetTypeCode Returns the TypeCode for value type Boolean.
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
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.
ToString()()() Converts the value of this instance to its equivalent string representation (either "True" or "False"). (Overrides ValueType..::.ToString()()().)
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.

Explicit Interface Implementations

Name Description
IConvertible..::.ToBoolean Infrastructure. For a description of this member, see IConvertible..::.ToBoolean.
IConvertible..::.ToByte Infrastructure. For a description of this member, see IConvertible..::.ToByte.
IConvertible..::.ToChar Infrastructure. This conversion is not supported. Attempting to use this method throws an InvalidCastException.
IConvertible..::.ToDateTime Infrastructure. This conversion is not supported. Attempting to use this method throws an InvalidCastException.
IConvertible..::.ToDecimal Infrastructure. For a description of this member, see IConvertible..::.ToDecimal..
IConvertible..::.ToDouble Infrastructure. For a description of this member, see IConvertible..::.ToDouble..
IConvertible..::.ToInt16 Infrastructure. For a description of this member, see IConvertible..::.ToInt16.
IConvertible..::.ToInt32 Infrastructure. For a description of this member, see IConvertible..::.ToInt32.

IConvertible..::.ToType Infrastructure. For a description of this member, see IConvertible..::.ToType.
IConvertible..::.ToUInt16 Infrastructure. For a description of this member, see IConvertible..::.ToUInt16.
IConvertible..::.ToUInt32 Infrastructure. For a description of this member, see IConvertible..::.ToUInt32.
IConvertible..::.ToUInt64 Infrastructure. For a description of this member, see IConvertible..::.ToUInt64.

Remarks

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

This value type implements interfaces IConvertible, IComparable, and System..::.IComparable<(Of <(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.
