Array.GetValue() Method in C# is used to gets the value of the specified element in the current Array. There are total 8 methods in the overload list of this method which are as follows:
- Array.GetValue(Int32, Int32)
- Array.GetValue(Int64, Int64)
- Array.GetValue(Int32)
- Array.GetValue(Int64)
- Array.GetValue(Int32, Int32, Int32)
- Array.GetValue(Int64, Int64, Int64)
- Array.GetValue(Int32[])
- Array.GetValue(Int64[])
In this article we are explaining Array.GetValue(Int32[]) and Array.GetValue(Int64[]) method.
Array.GetValue(Int32[]) method is used to get the value at the specified position in the multidimensional-dimensional Array. The indexes are passed to this method by a 1D array, that means the 1D array which is passed that contains the specified index as array element of 1D array, and the element is to be searched that is at that index which is in the 1D array. The indexes are specified as 32-bit integers.
Syntax:
public object GetValue (int[] index);
Here “index” is a 1D array of 32-bit integers that represent the index specifying the position of the element to be searched. searched.
Returns: This method returns the element at the specified index define by the passed 1D array to the GetValue method. The value is a 32-bit integer value.
Exceptions:
- ArgumentException: If the number of dimensions in the current array is not equal to the number of elements in index array which is passed to GetValue method.
- IndexOutOfRangeException: If the elements in index array defines a range which is outside the range of valid indexes for the corresponding dimension of the current array .
- ArgumentNullException: if the index array is null then it throws.
Array.GetValue(Int64[]) method is used to get the value at the specified position in the multidimensional-dimensional Array. The indexes are passed to this method by a 1D array, that means the 1D array which is passed that contains the specified index as array element of 1D array, and the element is to be searched that is at that index which is in the 1D array. The indexes are specified as 64-bit integers.
Syntax:
public object GetValue (long[] index);
Here, “index[]” is a 1D array of 64-bit integers that represent the index specifying the position of the element to be searched.
Returns: This method returns the element at the specified index define by the passed 1D array to the GetValue method. The value is a 32-bit integer value.
Exceptions:
- ArgumentException: If the number of dimensions in the current array is not equal to the number of elements in index array which is passed to GetValue method.
- ArgumentOutOfRangeException: If the elements in index array defines a range which is outside the range of valid indexes for the corresponding dimension of the current array .
- ArgumentNullException: if the index array is null then it throws.

},
{// array 2
{'G', 'H', 'I'},
{'J', 'K', 'L'}}
