C# Foreach Loop with DataGridView: Accessing Data and Row Manipulation

To use a foreach loop with a DataGridView in C#, you can utilize the 'Rows' property of the DataGridView and iterate through each row. Here's an example:

foreach (DataGridViewRow row in myDataGridView.Rows)
{
    // Access the data in the row using the 'Cells' property
    string cellValue = row.Cells[0].Value.ToString();
    // Do something with the cell data
}

In this example, we're looping through the 'Rows' property of the DataGridView named 'myDataGridView'. For each row, we access the value of the first cell in the row using the 'Cells' property and the index of the cell (0). We then convert that value to a string and store it in a variable named 'cellValue'. You can replace the comment with the code you want to execute for each row.
