Public Overrides Function CanConvertFrom ( _
    context As ITypeDescriptorContext, _
    sourceType As Type _
) As Boolean

Visual Basic (Usage)

Dim instance As EnumConverter
Dim context As ITypeDescriptorContext
Dim sourceType As Type
Dim returnValue As Boolean

returnValue = instance.CanConvertFrom(context, _
    sourceType)

public override bool CanConvertFrom(
    ITypeDescriptorContext context,
    Type sourceType
)

Visual C++

public:
virtual bool CanConvertFrom(
    ITypeDescriptorContext^ context, 
    Type^ sourceType
) override

JScript

public override function CanConvertFrom(
    context : ITypeDescriptorContext, 
    sourceType : Type
) : boolean

Parameters

context: Type: System.ComponentModel..::.ITypeDescriptorContext
An ITypeDescriptorContext that provides a format context.

sourceType: Type: System..::.Type
A Type that represents the type you wish to convert from.

Return Value

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

Remarks

This converter can only convert an enumeration object to and from a string.

The context parameter can be used to extract additional information about the environment this converter is being invoked from. This can be nullNothingnullptra null reference (Nothing in Visual Basic), so always check. Also, properties on the context object can return nullNothingnullptra null reference (Nothing in Visual Basic).
