How to write a text file from a .NET DataGridView control cell values?

Question

I have the following code that should loop through all the rows in my DataGridView, and write all their cell values to a text file.
However, it outputs all the rows, but only the first cell of each one, and not the other three cells.

string file_name = "C:\\test1.txt";

var objWriter = new System.IO.StreamWriter(file_name);

int count = dgv.Rows.Count;

for (int row = 0; row < count; row++)
{
    objWriter.WriteLine(dgv.Rows[row].Cells[0].Value.ToString());
}

objWriter.Close();

Solution

for (int row = 0; row < count; row++)
    {
        int colCount = dgv.Rows[row].Cells.Count; 
        for ( int col = 0; col < colCount; col++)  
        {
            objWriter.WriteLine(dgv.Rows[row].Cells[col].Value.ToString());

        }
        // record seperator could be written here.
    }

Although, it would be cleaner if you used a foreach loop.

Chris' answer is correct - you need to loop over the cells as well as the rows. One suggestion I'd make though is to use a foreach on the rows and cells collection - this will tidy the code a little and save needing to get the row from the rows collection for each column lookup.
