Interlocked.Add Interlocked.Add Interlocked.Add Interlocked.Add Method

Definition

Adds two integers and replaces the first integer with the sum, as an atomic operation.

Overloads

Add(Int32, Int32) Add(Int32, Int32) Add(Int32, Int32) Add(Int32, Int32)

Adds two 32-bit integers and replaces the first integer with the sum, as an atomic operation.

Add(Int64, Int64) Add(Int64, Int64) Add(Int64, Int64) Add(Int64, Int64)

Adds two 64-bit integers and replaces the first integer with the sum, as an atomic operation.

Add(Int32, Int32) Add(Int32, Int32) Add(Int32, Int32) Add(Int32, Int32)

Adds two 32-bit integers and replaces the first integer with the sum, as an atomic operation.

public:
 static int Add(int % location1, int value);
public static int Add (ref int location1, int value);
static member Add :  * int -> int
Public Shared Function Add (ByRef location1 As Integer, value As Integer) As Integer

Parameters

location1
Int32 Int32 Int32 Int32

A variable containing the first value to be added. The sum of the two values is stored in location1.

value
Int32 Int32 Int32 Int32

The value to be added to the integer at location1.

Returns

The new value stored at location1.

Exceptions

Remarks

This method handles an overflow condition by wrapping: if the value at location1 is Int32.MaxValue and value is 1, the result is Int32.MinValue; if value is 2, the result is (Int32.MinValue + 1); and so on. No exception is thrown.
