如何修复bug当将参数传递给报告rdlc winform时，本地处理exception未处理？
我正在做大学项目。 在那，他们想要一个真正的证书。 为此，我计划将TextBox字符串传递给report。
我用Google搜索在winform中传递参数。 然后我逐步完成了这个过程。 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“查看”菜单将其打开）;
2：右键单击“参数”节点，然后添加一个新参数，即：将其命名为“content”;
3：在.rdlc文件中，添加一个名为tbContent的文本框，并将其提交的快递设置为：
=参数！content.Value
4：转到包含您的记者视图控件的表单文件，并添加以下代码：
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：然后你可以将参数从表单上的TextBox传递给.rdlc文件;
我添加了using Microsoft.Reporting.WinForms; assembly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();
但它引发了exception：
本地处理exception未处理
this.reportViewer1.LocalReport.SetParameters（new ReportParameter [] {rp}）; 线。
这是剪贴板中的完整错误：

设置此：
this.reportViewer1.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Local;
并改变这个：
this.reportViewer1.LocalReport.ReportEmbeddedResource = "Report1.rdlc"
至
this.reportViewer1.LocalReport.ReportPath = "Report1.rdlc";
为了防止出现这种情况，我在重新组织项目文件夹后遇到了同样的问题，从而更改了报告文件路径。 我所要做的就是在ReportViewer的Choose Report ComboBox中重新选择报告，该报告可从右上角访问。
还要仔细检查您是否正确拼写了rdlc文件名。 例如，我的报告文件是ReportName.rdlc但我输入了this.reportViewer1.LocalReport.ReportPath = "ReportsName.rdlc";
