what does this mean?

Hi

I'm trying to work out what this is doing

int[,] kernel = { { -1, -1, -1 }, { -1, 8, -1 }, { -1, -1, -1 } };
int ksize = kernel.GetLength(0);


What I think is happening is:

The first line declares a dynamic multidimensional array of integers called kernal and puts the values { -1, -1, -1 }, { -1, 8, -1 }, { -1, -1, -1 } in it (3 rows of 3).
The second line declares an int called ksize and puts the length of kernal into it.

But is the length of kernal 3 or 9?
and what is (0) on the kernel.GetLength(0) used for?

Is this by any chance C#?

Although quite C like it is certainly not C or C++.

Sorry put it in wrong place

Rather than tell you the answer how about if we show you a way to learn the answers?

But is the length of kernal 3 or 9?

int ksize = kernel.GetLength(0); 

Check/display the value of ksize in your application. You could have a messagebox show you the value:

MessageBox.Show(ksize.ToString(), "The value is...");

what is (0) on the kernel.GetLength(0) used for?

Whenever you want to know something about the .NET framework a good place to start is the MSDN. For this question specially you can find the answer here:
