如何修复错误将参数传递给报告rdlc winform时未处理本地处理异常？

Question

我正在做大学项目。那样，他们想要一个真实的证明。为此，我计划传递TextBox字符串进行报告。

我用谷歌搜索在winform中传递参数。然后我逐步进行了此过程。我实现了。

步：

1：在Visual Studio 2010中，打开.rdlc文件，然后打开“报表数据”窗口（如果看不到此窗口，请转到“视图”菜单将其打开）；

2：右键单击“参数”节点，并添加新的参数，即：将其命名为“ content”；

3：在您的.rdlc文件中，添加一个名为tbContent的文本框，并将其字段express设置为：

= Parameters！content.Value

4：转到包含您的reporterview控件的Form文件，然后添加以下代码：

       this.reportViewer1.LocalReport.ReportEmbeddedResource

=“ TestReport.Report1.rdlc”；ReportParameter rp = new ReportParameter（“ content”，this.textBox1.Text）; this.reportViewer1.LocalReport.SetParameters（new ReportParameter [] {rp}）; this.reportViewer1.RefreshReport（）;

5：然后可以将参数从表单上的文本框传递到.rdlc文件；

我添加了using Microsoft.Reporting.WinForms;程序集参考。

 this.reportViewer1.LocalReport.ReportEmbeddedResource = "Report1.rdlc";

            ReportParameter rp = new ReportParameter("content", this.textBox1.Text);
            this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { rp });
            this.reportViewer1.RefreshReport();  

但这引发了异常：

在
this.reportViewer1.LocalReport.SetParameters（new ReportParameter [] {rp}）; 处未处理本地处理异常。线。

这是剪贴板中的完整错误：

Answer 1

设置这个：

this.reportViewer1.ProcessingMode = 
    Microsoft.Reporting.WinForms.ProcessingMode.Local;

并改变这一点：

this.reportViewer1.LocalReport.ReportEmbeddedResource = "Report1.rdlc" 

到

this.reportViewer1.LocalReport.ReportPath = "Report1.rdlc";
