TypeConverter.CanConvertFrom Method (ITypeDescriptorContext, Type)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Returns whether the type converter can convert an object from the specified type to the type of this converter.

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

public virtual bool CanConvertFrom(
	ITypeDescriptorContext context,
	Type sourceType
)

Parameters

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

Return Value

Type: System.Boolean
true if this converter can perform the conversion; otherwise, false.

Notes to Inheritors

For use as a type converter for custom-type attribute handling in XAML, you should define the CanConvertFrom(ITypeDescriptorContext, Type) signature with your implementation. Return true if sourceType is of type String; otherwise, false. Do not rely on information in context, it may be null. Do not throw if context is null; the other signature (CanConvertFrom(Type)) calls this one, passing a null context.

The base implementation always returns false.
