SetValue(Object, Int32)

Source:: Array.cs

Source:: Array.cs

Source:: Array.cs

Sets a value to the element at the specified position in the one-dimensional Array. The index is specified as a 32-bit integer.

public:
 void SetValue(System::Object ^ value, int index);

public void SetValue (object value, int index);

public void SetValue (object? value, int index);

member this.SetValue : obj * int -> unit

Public Sub SetValue (value As Object, index As Integer)

Parameters

value: Object

The new value for the specified element.

index: Int32

A 32-bit integer that represents the position of the Array element to set.

Exceptions

ArgumentException

The current Array does not have exactly one dimension.

InvalidCastException

value cannot be cast to the element type of the current Array.

IndexOutOfRangeException

index is outside the range of valid indexes for the current Array.

Remarks

The GetLowerBound and GetUpperBound methods can determine whether the value of index is out of bounds.

For more information about conversions, see Convert.

This method is an O(1) operation.

Note

If 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.

Applies to

SetValue(Object, Int32[])

Source:: Array.cs

Source:: Array.cs

Source:: Array.cs

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.

public:
 void SetValue(System::Object ^ value, ... cli::array <int> ^ indices);

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

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

member this.SetValue : obj * int[] -> unit

Public Sub SetValue (value As Object, ParamArray indices As Integer())

Parameters

value: Object

The new value for the specified element.

indices: Int32[]

A one-dimensional array of 32-bit integers that represent the indexes specifying the position of the element to set.

Exceptions

ArgumentNullException

ArgumentException

The number of dimensions in the current Array is not equal to the number of elements in indices.

InvalidCastException

value cannot be cast to the element type of the current Array.

IndexOutOfRangeException

Any element in indices is outside the range of valid indexes for the corresponding dimension of the current Array.

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 GetLowerBound and GetUpperBound methods can determine whether any of the values in the indices array is out of bounds.

For more information about conversions, see Convert.

This method is an O(1) operation.
