Question

I have a session which contains a datatable and also have a function which returns a datatable. I need to add these two. How can I do this?

The below code is to be replaced with correct code.

Session("Table")=Session("Table")+obj.GetCustomer()

…where obj is an object of the business layer.

The ‘+’ sign cannot be used to add these two, so how can I do this?

Answer 1

I would try something like this:

Dim MyDataSet1 As New DataSet()
Dim MyDataSet2 As New DataSet()

Dim dt1 As New DataTable() = ctype(Session("Table"), DataTable)
Dim dt2 As New DataTable() = obj.GetCustomer()

MyDataSet1.Tables.Add(dt1)
MyDataSet2.Tables.Add(dt2)

MyDataSet1.Merge(MyDataSet2)

Session("Table") = MyDataSet1.Tables(0)
