Question

I want to get top 10 rows from a DataTable in the same order as the previous DataTable.

With the code I have below, I can have it sorted in dt1 and import only 10 rows into dt2 but it’s not importing the rows in the sorted order. I need it to keep the sorted order. Your help will be much appreciated.

    DataTable dt2 = dt1.Clone(); 
    dt1.DefaultView.Sort = "x DESC"; 
    for (int i = 0; i < 10; i++)
    {
        dt2 .ImportRow(dt1.Rows[i]);
    }

Answer 1

Just use a query and sorting like this:

DataTable dt2 = dt.Clone();

//get only the rows you want
DataRow[] results = dt.Select("", "x DESC");

//populate new destination table
for(var i=0; i < 10; i++)        
    dt2.ImportRow(results[i]);

Hope it helps!
