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.
Assembly: System (in System.dll)
'Declaration Public Overridable Function CanConvertFrom ( _ context As ITypeDescriptorContext, _ sourceType As Type _ ) As Boolean
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.Booleantrue if this converter can perform the conversion; otherwise, false.
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 Nothing. Do not throw if context is Nothing; the other signature (CanConvertFrom(Type)) calls this one, passing a null context.
The base implementation always returns false.
