Syntax

Visual Basic (Declaration)

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

Visual Basic (Usage)

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

returnValue = instance.CanConvertFrom(context, _
    sourceType)

public virtual bool CanConvertFrom(
    ITypeDescriptorContext context,
    Type sourceType
)

Visual C++

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

JScript

public 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 want to convert from.

Return Value

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

Remarks

As implemented in this class, this method returns false, unless sourceType is an InstanceDescriptor.

Notes to Inheritors:

Override this method to provide your own conversion requirements.

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