BooleanConverter Class (System.ComponentModel)

.NET Framework Class Library

BooleanConverter Class

Provides a type converter to convert Boolean objects to and from various other representations.

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

Syntax

Visual Basic (Declaration)

<HostProtectionAttribute(SecurityAction.LinkDemand, SharedState := True)> _
Public Class BooleanConverter _
    Inherits TypeConverter

Visual Basic (Usage)

Dim instance As BooleanConverter

[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
public class BooleanConverter : TypeConverter

Visual C++

[HostProtectionAttribute(SecurityAction::LinkDemand, SharedState = true)]
public ref class BooleanConverter : public TypeConverter

JScript

public class BooleanConverter extends TypeConverter

Remarks

Note:
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

Note:

The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

This converter can only convert a Boolean object to and from a string.

For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.

Note:
You should never create an instance of a BooleanConverter. Instead, call the GetConverter method of the TypeDescriptor class. For more information, see the examples in the TypeConverter base class.

Examples

The following code example converts a variable of type Boolean to and from a string.

Visual Basic

Dim bVal As Boolean = True
Dim strA As String = "false"
Console.WriteLine(TypeDescriptor.GetConverter(bVal).ConvertTo(bVal, GetType(String)))
Console.WriteLine(TypeDescriptor.GetConverter(bVal).ConvertFrom(strA))

bool bVal=true;
string strA="false";
Console.WriteLine(TypeDescriptor.GetConverter(bVal).ConvertTo(bVal, typeof(string))); 
Console.WriteLine(TypeDescriptor.GetConverter(bVal).ConvertFrom(strA));

Visual C++

bool bVal(true);
String^ strA = "false";
Console::WriteLine( TypeDescriptor::GetConverter( bVal )->ConvertTo( bVal, String::typeid ) );
Console::WriteLine( TypeDescriptor::GetConverter( bVal )->ConvertFrom( strA ) );

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
