What is the difference between the Length property and the GetLength functi

Answer 1

GetLength takes an integer that specifies the dimension of the array that you're querying and returns its length. Length property returns the total number of items in an array:

int[,,] a = new int[10,11,12];
Console.WriteLine(a.Length);           // 1320
Console.WriteLine(a.GetLength(0));     // 10
Console.WriteLine(a.GetLength(1));     // 11
Console.WriteLine(a.GetLength(2));     // 12
