Syntax

public sealed class NullableBoolConverter : TypeConverter

Methods

CanConvertFrom(ITypeDescriptorContext, Type)

Determines whether this converter can convert an object of the specified type to the System.Nullable<T> type (using the System.Boolean type constraint on the generic).

Declaration

public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.
System.Type	sourceType	The type that you want to convert from.

Returns

Type	Description
System.Boolean	true if sourceType is a System.String, System.Boolean, or a System.Nullable<T> type (using the System.Boolean type constraint on the generic) that can be assigned from sourceType; otherwise, false.

Overrides

System.ComponentModel.TypeConverter.CanConvertFrom(System.ComponentModel.ITypeDescriptorContext, System.Type)

CanConvertTo(ITypeDescriptorContext, Type)

Always returns false.

Declaration

public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context
System.Type	destinationType

Returns

Type	Description
System.Boolean

Overrides

System.ComponentModel.TypeConverter.CanConvertTo(System.ComponentModel.ITypeDescriptorContext, System.Type)

ConvertFrom(ITypeDescriptorContext, CultureInfo, Object)

Converts the specified object to a System.Nullable<T> type (using the System.Boolean type constraint on the generic).

Declaration

public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context	An System.ComponentModel.ITypeDescriptorContext that provides a format context.
System.Globalization.CultureInfo	culture	The System.Globalization.CultureInfo to use as the current culture.
System.Object	value	The object to convert to a System.Nullable<T> type (using the System.Boolean type constraint on the generic).

Returns

Type	Description
System.Object	A System.Nullable<T> type (using the System.Boolean type constraint on the generic) that represents the converted object.

Overrides

System.ComponentModel.TypeConverter.ConvertFrom(System.ComponentModel.ITypeDescriptorContext, System.Globalization.CultureInfo, System.Object)

Exceptions

Type	Condition
System.NotSupportedException	The conversion attempt failed. value is not a System.String, System.Boolean, or System.Nullable<T> (using the System.Boolean type constraint on the generic) type.

ConvertTo(ITypeDescriptorContext, CultureInfo, Object, Type)

Not implemented.

Declaration

public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)

Parameters

Type	Name	Description
System.ComponentModel.ITypeDescriptorContext	context
System.Globalization.CultureInfo	culture
System.Object	value
System.Type	destinationType

Returns

Type	Description
System.Object

Overrides

System.ComponentModel.TypeConverter.ConvertTo(System.ComponentModel.ITypeDescriptorContext, System.Globalization.CultureInfo, System.Object, System.Type)

Exceptions

Type	Condition
System.NotImplementedException	Always throws.
