如何同时将参数和数据源传递给rdlc报告

Question

    private void Test_Load(object sender, EventArgs e)
    {
        try
        {

            string sql = "[companyid]   ,[companyname] ,[Shopid]   ,[shopname],[shopaddress],[shopphone],[fax], [footermsg],[footermsg_ar] FROM [shop] Where id  = '1' ";
            DataAccess.ExecuteSQL(sql);
            DataTable dt = DataAccess.GetDataTable(sql);
            ReportDataSource reportDSDetail = new ReportDataSource("DataSet1", dt);

            string sqli = "SELECT [logo] FROM [logo] Where id= '1' ";
            DataAccess.ExecuteSQL(sql);
            DataTable dts = DataAccess.GetDataTable(sql);
            string path = Application.StartupPath + @"\LOGO\";
            string imagePath = path + dts.Rows[0].ItemArray[0].ToString();
            ReportParameter pImageUrl = new ReportParameter("pName", "file://" + imagePath, true);
            this.reportViewer1.LocalReport.ReportPath =path+@"Rep.rdlc";
            this.reportViewer1.LocalReport.EnableExternalImages = true;
            this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { pImageUrl });
            this.reportViewer1.LocalReport.DataSources.Add(reportDSDetail);
            this.reportViewer1.RefreshReport();

        }
        catch (Exception ex)
        {
            MessageBox.Show("Exception=" + ex);
        }
    }

在 RDLC 报告中，我创建了一个名为 pName 的参数并与图像连接并配置了一个外部。我需要在报告中同时获取参数和数据源，我尝试了很多方法但都失败了。请帮助我解决此问题以获取 RDLC 报告中的参数和数据源

首先，您需要转到 Report Data 并像这样添加 Parameters

在添加参数 Right Click on textbox 之后，您要在其中显示 parameters--> Click Expression 并添加 Expression 像这样

其中 Showdt 是 parameter 姓名

并从 code behind 像这样一起传递 data source 和 parameters

ReportDataSource rds = new ReportDataSource();//pass Your Datasource
ReportViewer1.LocalReport.DataSources.Clear();
ReportParameter p1 = new ReportParameter("Showdt", "Date : " + DateTime.Now.ToShortDateString());
//you can add multiple parameter like this
this.ReportViewer1.LocalReport.SetParameters(new ReportParameter[]{p1}); 
 ReportViewer1.LocalReport.DataSources.Add(rds);
 ReportViewer1.LocalReport.Refresh();
