Find DataTable by DataTable.Id HELP!

There has to be an easy answer: I want to loop through multiple datatables... example:

for (int i = 1 ; i < 7 ; i ++ )
{
    DataTable dt = (DataTable) "dt" + i.toString();

    // do something with DataTable dt1 as DataTable
    //  ie开发者_JAVA百科...

    int x = dt.Rows.Count
}

The above code obviously does not work.. but how do you find a DataTable like you do FindControl with WebControls?? I can't figure it out.

Uhm, do you have

DataTable dt1 = new DataTable();
DataTable dt2 = new DataTable();
DataTable dt3 = new DataTable();
DataTable dt4 = new DataTable();
DataTable dt5 = new DataTable();
DataTable dt6 = new DataTable();
DataTable dt7 = new DataTable();

in your project?

You should then create a list of DataTables:

List<DataTable> datatables = new List<DataTable>();

datatables.Add(new DataTable());  // dt1 (now datatables[0])
datatables.Add(new DataTable());  // dt2 (now datatables[1])
datatables.Add(new DataTable());  // dt3 (now datatables[2])
datatables.Add(new DataTable());  // dt4 (now datatables[3])
datatables.Add(new DataTable());  // dt5 (now datatables[4])
datatables.Add(new DataTable());  // dt6 (now datatables[5])
datatables.Add(new DataTable());  // dt7 (now datatables[6])

Then you can loop like this:

foreach (DataTable dt in datatables)
{
    // do something with DataTable dt as DataTable
    //  ie...

    int x = dt.Rows.Count    
}
