Question

I have the following scenario:

Public Class MyType
{
   Public string A{ get;set;}
   Public string B{ get;set;}
}
.....
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("myNode", typeof(MyType)));

What is the most efficient way to locate a row that holds a MyType where A = “specific value” other than doing a for each?

Answer 1

Datatable.rows has a find() method, however I’ve never been satisfied with the speed of it if you’re dealing with a large datatable or many finds. If you’re only dealing with 2 columns of data, have a look at using a hashtable instead. They are VASTLY faster when it comes to searching.
