List<'T>.ConvertAll<'TOutput> Method (Converter<'T, 'TOutput>)
Converts the elements in the current List<'T> to another type, and returns a list containing the converted elements.
Assembly: mscorlib (in mscorlib.dll)
Return ValueType: System.Collections.Generic.List<'TOutput>
The type of the elements of the target array.
The Converter<'TInput, 'TOutput> is a delegate to a method that converts an object to the target type. The elements of the current List<'T> are individually passed to the Converter<'TInput, 'TOutput> delegate, and the converted elements are saved in the new List<'T>.
The current List<'T> remains unchanged.
This method is an O(n) operation, where n is Count.
The following 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 method. The 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.
