Question

What’s a good way to get data from a datatable to its corresponding object? I’m guessing there’s a more efficient and cleaner method than how I’m currently doing it:

var username = dt_user.rows[0].columns[0];

Thanks!

Check out the extensions in System.Data.DataSetExtensions. It provides a generic extension method Field with various overloads for DataRow.

var username = dt_user.rows[0].columns[0];
//becomes
var username = dt_user.rows[0].Field<String>(0);

The real power comes when accessing nullable primative types:

var integerValue = dataRow.Field<Int32?>("ColumnName");
