UIntPtr.Add(UIntPtr, Int32) UIntPtr.Add(UIntPtr, Int32) UIntPtr.Add(UIntPtr, Int32) UIntPtr.Add(UIntPtr, Int32) Method

Definition

Adds an offset to the value of an unsigned pointer.

public:
 static UIntPtr Add(UIntPtr pointer, int offset);
public static UIntPtr Add (UIntPtr pointer, int offset);
static member Add : unativeint * int -> unativeint
Public Shared Function Add (pointer As UIntPtr, offset As Integer) As UIntPtr

Parameters

pointer
UIntPtr UIntPtr UIntPtr UIntPtr

The unsigned pointer to add the offset to.

offset
Int32 Int32 Int32 Int32

The offset to add.

Returns

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

Examples

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.

using System;

public class Example
{
   public static void Main()
   {
      int[] arr = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
      UIntPtr ptr = (UIntPtr) arr[0];
      for (int ctr = 0; ctr < arr.Length; ctr++)
      {
         UIntPtr newPtr = UIntPtr.Add(ptr, ctr);
         Console.Write("{0}   ", newPtr);
      }      
   }
}
// The example displays the following output:
//       1   2   3   4   5   6   7   8   9   10
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

Remarks

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.
