BuiltInRoleConverter.ConvertTo Method

Definition

Converts the given object to another type.

public:
 override System::Object ^ ConvertTo(System::ComponentModel::ITypeDescriptorContext ^ context, System::Globalization::CultureInfo ^ culture, System::Object ^ value, Type ^ destinationType);
public override object ConvertTo (System.ComponentModel.ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value, Type destinationType);
override this.ConvertTo : System.ComponentModel.ITypeDescriptorContext * System.Globalization.CultureInfo * obj * Type -> obj
Public Overrides Function ConvertTo (context As ITypeDescriptorContext, culture As CultureInfo, value As Object, destinationType As Type) As Object

Parameters

context
ITypeDescriptorContext

A formatter context.

culture
CultureInfo

The culture into which value will be converted.

value
Object

The object to convert.

destinationType
Type

The type to convert the object to.

Returns

The converted object.

Exceptions

destinationType is Nothing.

The conversion cannot be performed.

Remarks

The most common types to convert to and convert from are string objects. The default implementation makes a call to ToString on the object if the object is valid and if the destination type is String.

The context parameter can be used to extract additional information about the environment this converter is being invoked from. This can be Nothing, so always check. Also, properties on the context object can return Nothing.

This type converter supports the Visual Basic User object.
