Public Overridable Function CanConvertFrom ( _
    context As ITypeDescriptorContext, _
    sourceType As Type _
) As Boolean
public virtual bool CanConvertFrom(
    ITypeDescriptorContext context,
    Type sourceType


  • 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 Silverlight 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 nulla null reference (Nothing in Visual Basic). Do not throw if context is nulla null reference (Nothing in Visual Basic); the other signature (CanConvertFrom(Type)) calls this one, passing a null context.

The base implementation always returns false.
