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: In 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 techfortech { class TECH { // 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.
