UIntPtr.Add Method (UIntPtr, Int32)

.NET Framework (current version)
 

Adds an offset to the value of an unsigned pointer.

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

Public Shared Function Add (
	pointer As UIntPtr,
	offset As Integer
) As UIntPtr

Parameters

pointer
Type: System.UIntPtr

The unsigned pointer to add the offset to.

offset
Type: System.Int32

The offset to add.

Return Value

Type: System.UIntPtr

A new unsigned pointer that reflects the addition of offset to pointer.

The Add method does not throw an exception if the result is too large to represent as a pointer on the specified platform. Instead, the addition operation is performed in an unchecked context.

Languages that do not support operator overloading or custom operators can use this method to add an offset to the value of an unsigned pointer.

The following example instantiates a UIntPtr object that points to the beginning of a ten-element array, and then calls the Add method to iterate the elements in the array.

Module Example
   Public Sub Main()
      Dim arr() As Integer = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
      Dim ptr As UIntPtr = CType(arr(0), UIntPtr)
      For ctr As Integer= 0 To arr.Length - 1
         Dim newPtr As UIntPtr = UIntPtr.Add(ptr, ctr)
         Console.Write("{0}   ", newPtr)
      Next
   End Sub
End Module
' The example displays the following output:
'       1   2   3   4   5   6   7   8   9   10
