Question

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字符串传递给报告。

我用googled在winform中传递参数。然后我逐步完成了这个过程。我实现了。

步骤：

1：在Visual Studio 2010中，打开您的   .rdlc文件，并打开“报告数据”   窗口（如果你看不到这个   窗口，转到“查看”菜单将其打开）;

2：右键单击“参数”节点，   并添加一个新参数，即：命名它   “内容“;

3：在你的.rdlc文件中，添加一个文本框，   将其命名为tbContent，并设置其归档   表达：

=参数！content.Value

4：转到包含的表单文件   你的记者视图控制，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（新   ReportParameter [] {rp}）;               this.reportViewer1.RefreshReport（）;

5：然后你可以传递参数   从表单上的TextBox到.rdlc   文件;

我添加了using Microsoft.Reporting.WinForms;程序集引用。

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

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

但它引发了异常：

本地处理异常是未经处理的 this.reportViewer1.LocalReport.SetParameters（新 ReportParameter [] {rp}）; 线。

以下是剪贴板中的完整错误：

Answer 1

设置：

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";

Answer 2

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，该报告可以从右上角访问。

Answer 3

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";

Answer 4

您可以很好地使用嵌入式，只是不要忘记在RDLC路径中包括名称空间。程序集名称空间以及所有可能的子名称空间都是必需的，作为报告的完整名称空间路径。

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

或

reportViewer1.LocalReport.ReportEmbeddedResource = "assemblyname.subnamespace.Report1.rdlc"

Answer 5

我刚刚在“NuGet 包管理器控制台”中运行了 Install-Package Microsoft.SqlServer.Types，一切正常。

如何修复bug当传递参数报告rdlc winform时，本地处理异常未处理？
