Represents a method that converts an object from one type to another type.

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

type Converter<'TInput, 'TOutput> = 
    delegate of 
        input:'TInput -> 'TOutput

Parameters

input
Type: TInput

The object to convert.

Return Value

Type: TOutput

The TOutput that represents the converted TInput.

Type Parameters

inTInput

The type of object that is to be converted.

outTOutput

The type the input object is to be converted to.

This delegate is used by the ConvertAll<'TInput, 'TOutput> method of the Array class and the ConvertAll<'TOutput> method of the List<'T>class to convert each element of the collection from one type to another.

This section contains two code examples. The first demonstrates the Converter<'TInput, 'TOutput> delegate with the ConvertAll<'TInput, 'TOutput> method of the Array class, and the second demonstrates the delegate with the ConvertAll<'TOutput> method of the List<'T> generic class.

Example 1

The following code example defines a method named PointFToPoint that converts a PointF structure to a Point structure. The example then creates an array of PointF structures, creates a Converter<PointF, Point> delegate (Converter(Of PointF, Point) in Visual Basic) to represent the PointFToPoint method, and passes the delegate to the ConvertAll<'TInput, 'TOutput> method. The ConvertAll<'TInput, 'TOutput> method passes each element of the input list to the PointFToPoint method and puts the converted elements into a new list of Point structures. Both lists are displayed.

No code example is currently available or this language may not be supported.

Example 2

The following code example defines a method named PointFToPoint that converts a PointF structure to a Point structure. The example then creates a List<'T> of PointF structures, creates a Converter<PointF, Point> delegate (Converter(Of PointF, Point) in Visual Basic) to represent the PointFToPoint method, and passes the delegate to the ConvertAll<'TOutput> method. The ConvertAll<'TOutput> method passes each element of the input list to the PointFToPoint method and puts the converted elements into a new list of Point structures. Both lists are displayed.
