我已经安装了所有需要报告查看器的软件包，但仍然显示有错误，应用所有格式路径，但仍然面临问题。

this.reportViewer1.LocalReport.ReportPath = Application.StartupPath + @"C: \Users\nazir\OneDrive\Documents\Nazam pos\Reportproduct.rdlc";
            
    this.reportViewer1.LocalReport.DataSources.Clear();
    
    DataSet1 ds = new DataSet1();
    SqlDataAdapter da = new SqlDataAdapter();
    
    cn.Open();
    
    da.SelectCommand = new SqlCommand("select p.pcode ,p.barcode,p.pdesc,b.brand,c.category,p.purchase,p.price, p.qty, p.reorder  from tblProducts as p inner join tblBrand as b on p.bid=b.id inner join tblCategory as c on p.cid=c.id ", cn);
    da.Fill(ds.Tables["dtproduct"]);
    
    cn.Close();
