Q: 

In .Net and c# DataTable.Select(string, string) method Question

What if we write filterExpression equal to null or "" ? Will all the rows be selected?

+2  A: 

Yes, I believe so.

In fact I more than believe so - having looked at Reflector (unfortunately the MSDN topic doesn't say anything about empty expressions) a filter is only applied if the expression is not empty or null.

That said - why bother doing that? Just iterate over the Rows or call the Select() method.
