Question

我在我的项目中使用RDLC报告。

protected void btnview_Click(object sender, EventArgs e)
    {
        ReportViewer1.ProcessingMode = ProcessingMode.Local;
        ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Report.rdlc");
        MyDataset dsreceipt = GetDataItem("select * from tblGeneratedReceipt ");
        ReportDataSource datasource = new ReportDataSource("Receipt", dsreceipt.Tables[0]);
        ReportViewer1.LocalReport.DataSources.Clear();
        ReportViewer1.LocalReport.DataSources.Add(datasource);

    }

    private MyDataset GetDataItem(string p)
    {
        SqlCommand cmd = new SqlCommand(p,conn);
        SqlDataAdapter adp = new SqlDataAdapter(cmd);
        MyDataset rec = new MyDataset();
        adp.Fill(rec, "DataTable1");
        return rec;
    }

我在网上收到错误 private MyDataset GetDataItem（string p） 错误是关于缺少程序集引用

我通过ReportViewer控件看到了类似的内容;你可以检查你的bin目录中是否有以下正确的版本： -

• Microsoft.ReportViewer.Common.dll
• Microsoft.ReportViewer.ProcessingObjectModel.dll
• Microsoft.ReportViewer.WebForms.dll
• Microsoft.ReportViewer.WinForms.dll
