DataTable, How to conditionally delete rows

Question

I\'m engaged in a C# learning process and it is going well so far. I however just now hit my first \"say what?\" moment.

The DataTable offers random row access to it

Answer 1

Extension method based on Linq

public static void DeleteRows(this DataTable dt, Func predicate)
{
    foreach (var row in dt.Rows.Cast().Where(predicate).ToList())
        row.Delete();
}

Then use:

DataTable dt = GetSomeData();
dt.DeleteRows(r => r.Field("Amount") > 123.12 && r.Field("ABC") == "XYZ");
