Question

I want to extend the System.Data.DataRow class, so I made the following code (and added the using keyword in my class)

namespace MyExtension
{
     public static class DataRowExt
      {
          public static string ToNullableDate(this DataRow dr)
          { return something;}
    }
}

However, when I try the following code, the ToNullableDate does not show up in Intellisense:

DataRow d = new DataRow();
d["Column"].ToNullableDate(); // ToNullableDate does not show up

Is there anything missing on my extension method statement? Or should I just create a new class and inherit from the DataRow class instead?

thanks

Answer 1

The extension method would be off, d, not off the indexer.

FYI, you can just do this:

DataRow d = new DataRow();
d["Column"] as DateTime?;
