Boolean Structure

Represents a Boolean value.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

Visual Basic

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Structure Boolean _
    Implements IComparable, IConvertible, IComparable(Of Boolean),  _
    IEquatable(Of Boolean)

[SerializableAttribute]
[ComVisibleAttribute(true)]
public struct Boolean : IComparable, IConvertible, 
    IComparable<bool>, IEquatable<bool>

Visual C++

[SerializableAttribute]
[ComVisibleAttribute(true)]
public value class Boolean : IComparable, 
    IConvertible, IComparable<bool>, IEquatable<bool>

[<Sealed>]
[<SerializableAttribute>]
[<ComVisibleAttribute(true)>]
type Boolean =  
    struct
        interface IComparable
        interface IConvertible
        interface IComparable<bool>
        interface IEquatable<bool>
    end

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 it 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.

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.
