How to get a DataTable object from a database using its tablename in C#?
===

im trying to get a DataTable object out of database using the table name that i have already .
how can i do that ? 
i have already tried :

    DataTable table = new DataTable(TableName);

but i believe this is wrong ( how  is the application supposed to know where that table name comes from or where to search for it ? ) 
i tried using con.GetSchema("Tables") , but that gives out only table names which are strings, and not DataTable objects . 
any help is appreciated .
