Question

Let suppose there are three columns in my DataTable

1. code

2. name

3. color

If I know the code and name, how can I update the color of that specific row whose code and name match my criteria? I want to do this without using Loops!

Answer 1

You can use LINQ:

DataRow dr = datatable.AsEnumerable().Where(r => ((string)r["code"]).Equals(someCode) && ((string)r["name"]).Equals(someName)).First();
dr["color"] = someColor;

Of course I’m assuming all those criteria are strings. You should change the casts to the correct types.
