Safely Removing DataRow In ForEach

Question

I don\'t understand why this code does not work.

foreach (DataRow dataRow in dataTable.Rows)
{
    if (true)
    {
        dataRow.Delete();
    }
}
<         


        

Answer 1

Safest way - use for loop

for (int i = datatable.Rows.Count - 1; i >= 0; i--) 
{
    if (true)
    {
        datatable.Rows[i].Delete();
    }
}

Don't forget to AcceptChanges to remove all marked rows:

datatable.AcceptChanges();
