[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Adds two 32-bit integers and replaces the first integer with the sum, as an atomic operation.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- location1
- Type:
System.Int32
%
A variable that contains the first value to be added. The sum of the two values is stored in location1.
- value
- Type: System.Int32
The value to be added to the integer at location1.
| Exception | Condition |
|---|---|
| NullReferenceException | The address of location1 is a null pointer. |
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.
