【问题描述】：
我正在做大学项目。在那，他们想要一个真正的证书。为此，我打算将TextBox 字符串传递给报告。
我搜索过在 winform 中传递参数。然后我一步一步地得到了这个过程。我实现了。
步骤：
1：在 Visual Studio 2010 中，打开您的 .rdlc 文件，然后打开“报告数据” 窗口（如果你看不到这个 窗口，进入查看菜单打开它）；
2：右键单击“参数”节点， 并添加一个新参数，即：命名它 “内容”；
3：在您的 .rdlc 文件中，添加一个文本框， 将其命名为 tbContent，并设置其字段 快递到：
=Parameters!content.Value
4：转到您的表单文件，其中包括 你的reporterview控件，并添加 以下代码：
this.reportViewer1.LocalReport.ReportEmbeddedResource= “TestReport.Report1.rdlc”; ReportParameter rp = new ReportParameter(“内容”, this.textBox1.Text); this.reportViewer1.LocalReport.SetParameters（新 报告参数[] { rp }); this.reportViewer1.RefreshReport();
5：那么就可以传参数了 从表单上的 TextBox 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();
但它会抛出异常：
本地处理异常是 未处理
this.reportViewer1.LocalReport.SetParameters（新 报告参数[] { rp }); 行。
这是剪贴板中的完整错误：

我昨天晚上开始搜索这个问题的解决方案。我读了很多这样的问题。这个问题影响了很多人。（主要是vb.net）其中一个肯定得到了解决方案。但他们没有分享。我继续搜索。
