If you want to separate the table from dataset, then take a new datatable and assign it something like this dt = ds.Tables[n].

If you want some records from a particular table, the create a new datatable and add new rows from the dataset's table.

Here is some thing I do in my project. In the below example I am getting dataset from different tables User and Roles. One my stored procedure is executed and I have my dataset I am using

ds.Tables[0].AsEnumerable()

- to get the data from data table in to userinfo. Further I am using

ds.Tables[1].AsEnumerable()

to get access to the second table in the dataset. You can try to do in your case as well.

SQL

DataSet ds = dm.ExecuteQuery("SpGetUserDetails", parameters);
 User userInfo = (from r in ds.Tables[0].AsEnumerable()
                 select new User
                 {
                     FullName = r["FirstName"].ToString() + " " + r["LastName"].ToString(),
                     FirstName = r["FirstName"].ToString(),
                     MiddleName = r["MiddleName"].ToString(),
                     LastName = r["LastName"].ToString(),
                     EmailId = r["EmailId"].ToString()
                  }).SingleOrDefault();

userInfo.Roles =(from r in ds.Tables[1].AsEnumerable()
                 select new UserRoles
                 {
                     UserRoleMappingId = Convert.ToInt32(r["UserRoleMappingId"].ToString()),
                     UserRoleId = Convert.ToInt32(r["UserRoleId"].ToString()),
                     UserId = Convert.ToInt32(r["UserId"].ToString()),
                      RoleName = r["RoleDescription"].ToString()
                }).ToList();

Hope this helps.
