Error While retreiving data from wcf service in datatable.

Question

User-1409360894 posted

I have created a WCF Service which is returning a DataTable. It is successfully build and hosted in IIS7 and also working fine when i am returning a string only.

but it gives me error (below) when i am returning a DataTable.

"The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error."

This is how i am calling my WCF Service.

Service1Client client1 = new Service1Client();
            dt = client1.GetNewData(16);
            GridView1.DataSource = dt;
            GridView1.DataBind();

Please help me its urgent.

Thanks in advance.

Did you change the WCF Service method's return type? If so, did you update your Service Reference or reference the newly-created DLL?

Make sure you set the 'TableName' property on the DataTable.
