推荐答案

中使用此代码.如果要添加数据，则将有所帮助.

Go through this logic. If you are adding data then this will help.

DataTable table = new DataTable();
     table.Columns.Add("From", typeof(int));
     table.Columns.Add("To", typeof(int));
     for (int i = 1; i < 10; i++)
     {
         table.Rows.Add(i, i + 1);
         i++;
     }

     GridView1.DataSource = table;

如果您要从数据库中获取数据，请详细说明.

If you are getting data from database then please elaborate some more.
