How do I access a row of a 2-dimensional array in C#? I want to get the count of row i.
Thanks!

I know this is old, but the link has changed. I guess this is why you don't just post a url. dotnetperls.com/2dSteveB– SteveB2022-02-22 16:21:47 +00:00Commented Feb 22, 2022 at 16:21

The question really depends on what type of 2D array you are thinking about and what dimension your row is.
Proper 2D array
// Init
var arr = new int[5,10];
// Counts
arr.GetLength(0) // Length of first dimension: 5
arr.GetLength(1) // Length of second dimension: 10
Jagged "2D" array
// Init
var arr = new int[3][];
// Initially arr[0],arr[1],arr[2] is null, so we have to intialize them:
arr[0] = new int[5];
arr[1] = new int[4];
arr[2] = new int[2];
// Counts
arr.Length // Length of first dimension
// In this case the "second dimension" (if you can call it that) is of variable size
arr[0].Length // Length: 5
arr[1].Length // Length: 4
arr[2].Length // Length: 2

Thanks, 2d arrays are a lot different in C#
This will also work,
string[,] a = new string[,]
{
{"ant", "aunt"},
{"Sam", "Samantha"},
{"clozapine", "quetiapine"},
{"flomax", "volmax"},
{"toradol", "tramadol"}
};
// a[1,1] is equal to Samantha
