Array.LongLength Property is used to get a 64-bit integer that represents the total number of elements in all the dimensions of the Array.
Syntax:
public long LongLength { get; }
Property Value: This property returns a 64-bit integer that represents the total number of elements in all the dimensions of the Array.
Example:
// C# program to illustrate the // Array.LongLength Property using System;
namespace geeksforgeeks {
class GFG {
// Main Method
public static void Main()
{
// Two-dimensional array
int [, ] intarray = new int [, ] { { 1, 2 },
{ 3, 4 },
{ 5, 6 },
{ 7, 8 } };
// The same array with dimensions
// specified 4 row and 2 column.
int [, ] intarray_d = new int [4, 2] { { 1, 2 },
{ 3, 4 },
{ 5, 6 },
{ 7, 8 } };
Console.Write( "Total Number of Elements in intarray: " );
// using LongLength property
Console.Write(intarray.LongLength);
// getting the type of returned value
Console.WriteLine( "\nType of returned Length: " + (intarray.LongLength).GetType());
// showing difference between Length
// and LongLength property by getting
// the type of the both property's
// returned value
Console.Write( "\nTotal Number of Elements in intarray_d: " );
// using Length property
Console.Write(intarray_d.Length);
// getting the type of returned value
Console.WriteLine( "\nType of returned Length: " + (intarray_d.Length).GetType());
Console.Write( "\nTotal Number of Elements in intarray_d: " );
// using LongLengthLength property
Console.Write(intarray_d.LongLength);
// getting the type of returned value
Console.WriteLine( "\nType of returned Length: " + (intarray_d.LongLength).GetType());
}
} } |
Output:
Total Number of Elements in intarray: 8 Type of returned Length: System.Int64 Total Number of Elements in intarray_d: 8 Type of returned Length: System.Int32 Total Number of Elements in intarray_d: 8 Type of returned Length: System.Int64
Note: In the above program you can see that Array.Length
property always returns the length of the type System.Int32 but Array.LongLength
property always returns the length of the type System.Int64.
