Now I want to take this information into DataTable by dynamically adding columns and rows to DataTable.

				dt3.Columns.Add(dc2);	<br />

Is the "double" type is faster than "float" type in .Net when using them in loops?
I sensed in my experience that it is true. somebody has any idea about it?
and why it must be true?

I'm guessing that if you've seen double as being faster it is probably because the processor's native floating point representation is a double and floats (although they save memory) will be slower as a result because the processor converts them internally to doubles, processes it then converts it back. But, that is just my guess.
