Represents a Boolean value.
Namespace: System
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 | |
|---|---|---|
.gif "Public method") |
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).) |
.gif "Protected method") |
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.) |
.gif "Static member") |
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. |

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.
