System.Array.SetValue Method

Sets a value to the element at the specified position in the multidimensional Array. The indexes are specified as an array of 32-bit integers.

Syntax

public void SetValue (object value, params int[] indices)

Parameters

value
The new value for the specified element.
indices
A one-dimensional array of 32-bit integers that represent the indexes specifying the position of the element to set.

Exceptions

TypeReason
ArgumentNullException indices is null.
ArgumentExceptionThe number of dimensions in the current instance is not equal to the number of elements in indices.
IndexOutOfRangeExceptionAt least one element in indices 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 number of elements in indices must equal the number of dimensions in the Array. All elements in the indices array must collectively specify the position of the desired element in the multidimensional Array.

The Array.GetLowerBound(int) and Array.GetUpperBound(int) methods can determine whether any of the values in the indices array is out of bounds.

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.
