I've installed ReportViewer and I created my report using SQL Server Report Builder and changed .rdl to .rdlc and copied the report in to my win app but I don't know how to set the ReportDataSource

I've created a dataset in my win app and this is my code:

reportViewer1.Reset();
reportViewer1.LocalReport.DataSources.Clear(); 
reportViewer1.LocalReport.ReportPath = ("rptStockCount.rdlc"); 
reportViewer1.LocalReport.DataSources.Add(new ReportDataSource("DataSet1")); 
reportViewer1.RefreshReport();

and this is the error: cannot create a data reader from data set 1

Any suggestion or help?
