Hi Experts,

Thanks For attention.

C#

var results = from table1 in tree.AsEnumerable()
                     join table2 in direct.AsEnumerable() on (int)table1["ID"] equals (int)table2["ID"]
                     select new
                     {
                         ID= (int)table1["ID"],
                         Name = (int)table1["Name"],
                         MobileNumber= (int)table1["MobileNumber"],
                         Address= (int)table2["Address"],
                         FatherName= (int)table2["FatherName"],

                     }

I want the var results convert into a DataTable.
Like:

DataTable dt=result;

Hi,
Use this function:

C#

public DataTable ToDataTable(System.Data.Linq.DataContext ctx, object query)
{
     if (query == null)
     {
          throw new ArgumentNullException("query");
     }
     
     IDbCommand cmd = ctx.GetCommand(query as IQueryable);
     SqlDataAdapter adapter = new SqlDataAdapter();
     adapter.SelectCommand = (SqlCommand)cmd;
     DataTable dt = new DataTable("sd");

     try
     {
          cmd.Connection.Open();
          adapter.FillSchema(dt, SchemaType.Source); 
          adapter.Fill(dt);
     }
     finally
     {
          cmd.Connection.Close();
     }
     return dt;
}

This code is given with the reference of this article[^].

Hope it helps.!

create a datatable with same structure of result
ie.

DataTable dt = new DataTable();
               dt.Columns.Add("ID", typeof(int));
               dt.Columns.Add("Name", typeof(int));
               dt.Columns.Add("MobileNumber", typeof(int));
               dt.Columns.Add("Address", typeof(int));
               dt.Columns.Add("FatherName", typeof(int));
               var results = from table1 in tree.AsEnumerable()
                             join table2 in direct.AsEnumerable() on (int)table1["ID"] equals (int)table2["ID"]
                             select new
                             {
                                 ID = (int)table1["ID"],
                                 Name = (int)table1["Name"],
                                 MobileNumber = (int)table1["MobileNumber"],
                                 Address = (int)table2["Address"],
                                 FatherName = (int)table2["FatherName"],
                             };
               foreach (var item in results)
               {
                   DataRow dr = dt.NewRow();
                   dr["ID"] = item.ID;
                   dr["Name"] = item.Name;
                   dr["MobileNumber"] = item.MobileNumber;
                   dr["Address"] = item.Address;
                   dr["FatherName"] = item.FatherName;
                   dt.Rows.Add(dr);
               }
