Iterating through DataGridViewRow columns

How can I iterate through DataGridViewRow columns? I just want to get the number of columns that I have and go through them and get the va开发者_JS百科lues.

You can use Cells property to get all values row have

foreach(DataGridViewCell cell in row.Cells)

    get value by    cell.Value
}

and number of columns is equal to number of cells
