Parameters

value

The new value for the specified element.

index1

A 32-bit integer that represents the first-dimension index of the Array element to set.

index2

A 32-bit integer that represents the second-dimension index of the Array element to set.

Exceptions

Type	Reason
ArgumentException	The current instance does not have exactly two dimensions.
IndexOutOfRangeException	At least one of index1 or index2 is outside the range of valid indices for the corresponding dimension of the current instance.
InvalidCastException	value is not assignment-compatible with the element type of the current instance.

Remarks

The Array.GetLowerBound(int) and Array.GetUpperBound(int) methods can determine whether any of the indexes is out of bounds.

For more information about conversions, see Convert.

This method is an O(1) operation.

Note:

If erload:System.Array.SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. The value of the element is not a null reference, and cannot be found by searching for a null reference.
