Joining Two DataTables into Single DataTable

Here I am going to explaing how to joing two datatables into a single DataTable.

Now I have a method which accepts two DataTables and returns a single DataTable which contains the Data of both the datatable.
Note:Structure of the both datatable must be same.

Private DataTable JoinDataTable(DataTable dt1,DataTable dt2)
DataTable dt = new DataTable();
DataRow dr;
dt = dt1.clone();// or you can clone the dt2 also like dt = dt2.clone();
for (int i=0;i{
dr = dt.NewRow();
for(int col1=0;dt1.Columns.Count;col1++)
dr[col1] = dt1.Rows[i][col1];
//Similarly Add the second DataTable
for (int j=0;j{
dr = dt.NewRow();
for(int col2=0;dt2.Columns.Count;col2++)
dr[col2] = dt2.Rows[j][col2];

return dt;

if both the structures are same means then we can use SELECT statement like
"select name,num from table1,table2" .....
where name belongs to table1,num belongs to table2
