I have got a datatable with several rows. I want to add a column of type int.<br />
If I do following I get an error: 'dataType' argument cannot be null.<br />
Parameter name: dataType<br />
<br />
&nbsp;ds.Tables[0].Columns.Add(&quot;<wbr />NewId&quot;, System.Type.GetType(&quot;Syste<wbr />m.Int&quot;));<br />
<br />
After I have created the column I will loop through the rows in the table and fill values in the new column. How can I add this new int column?

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
