Question

How do you use the Array.GetLength function in C#?

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

Answer 1

In mathematical term, we call as m rows and n columns, so the results is product of m*n for a two dimensional array. In this case GetLength(0) = m rows and GetLength(1)= n columns. For e.g see below example

string[,] stocks ={{"RELIND","Reliance Industries","1006.30"},{"TATMOB","Tata Mobiles","504.10"},{"ALST","Allstate","800.00"}, {"GE","GE Motors","810.00"}
};

The stocks arrays return GetLength(0)= 4 and GetLength(1)=3 and length =12
