get string with foreach in datagridview

Question

I create a function with the aim to show the concatenated string to the DataGrid that I made such:

file1.exe, file2.docx, file3.mp3

how to display that way? I have tried it but messagebox displays an empty string.

This is the code :

public void View()
{
    string namaFile = string.Empty;
    foreach (DataGridViewRow row in DGVDekripsi.Rows)
    {
       string NameFile = (string)row.Cells[0].Value;
       namaFile += NameFile + ",";
    }
    MessageBox.Show(namaFile);
}

Are you sure your your first cells of all rows are not empty? Did you debug your code? Your code seems fine to me. — Soner Gönül, Mar 02 '14 at 12:15

The only way I could see your code not working is if you had no rows in your DataGridView, so there was nothing to iterate over. Even if you had several rows and they all had empty names, you'd at least get a string with several commas in it.

Also, here's a slightly shorter way to get your list of names, using LINQ:

var allNames = string.Join(",",
               DGVDekripsi.Rows.Cast<DataRow>().Select(x => x.Field<string>(0)));

Thanks, this using 'Join'. I will also try it. – sloqye Mar 02 '14 at 12:30
