Question

I have a question about the datarow and how I can update it…

I have a datatable with two columns, id and name. I do the following:

    // data table has data at this point....      myTable.Columns.Add('Fri');      foreach(DataRow r in myTable.Rows) {         r['Fri'] = 4;      } 

What I am trying to do here is add a new columnm, ‘Fri’. Then for each entry already in the data table I want to have the value in column Fri as 4. Thanks for the help.

Answer 1

The code you listed should work, but if you want to later use the Fri value as an integer you should declare the data type of the column like this:

myTable.Columns.Add('Fri', typeof(int));
