Multidimensional vs Jagged array

Question

I have used a MultiDimesional Array as follows

  string[,] Columns = { { \"clientA\", \"clientB\" }}

    if (Columns.Length != 0)
            {
                     


        

Answer 1

This should work:

 string[][] Columns = { 
     new string[] { "ClientA", "ClientB" } 
 };

If you need to add more elements to the array, it should look like this:

string[][] Columns = { 
    new string[] { "ClientA", "ClientB" },
    new string[] { "ClientC", "ClientD" },
    new string[] { "ClientE", "ClientF" } 
};

Then you can access each element with the code below

Columns[0][0] // Client A
Columns[0][1] // Client B
Columns[1][0] // Client C
Columns[1][1] // Client D
// etc.
