DataRow: Select cell value by a given column name

Which version of .NET are you using? Since .NET 3.5, there’s an assembly System.Data.DataSetExtensions, which contains various useful extensions for dataTables, dataRows and the like.

You can try using

row.Field<type>("fieldName");

if that doesn’t work, you can do this:

DataTable table = new DataTable();
var myColumn = table.Columns.Cast<DataColumn>().SingleOrDefault(col => col.ColumnName == "myColumnName");
if (myColumn != null)
{
    // just some roww
    var tableRow = table.AsEnumerable().First();
    var myData = tableRow.Field<string>(myColumn);
    // or if above does not work
    myData = tableRow.Field<string>(table.Columns.IndexOf(myColumn));
}
