Question

我尝试将参数传递给报告时出错。

Microsoft.ReportViewer.WebForms.dll中发生了未处理的“Microsoft.Reporting.WebForms.LocalProcessingException”类型异常。

我的代码：

ReportViewer reportViwer = new ReportViewer();
reportViwer.ProcessingMode = ProcessingMode.Local;

reportViwer.LocalReport.ReportEmbeddedResource = "MyReport.Report1.rdlc";

List<ReportParameter> listReportParameter = new List<ReportParameter>();

listReportParameter.Add(new ReportParameter("Name", "Test"));

reportViwer.LocalReport.SetParameters(listReportParameter);

错误发生在“SetParameters”中。

Answer 1

感谢我解决问题的提示。

当我添加引用“Microsoft.ReportViewer.WebForms.dll”时，Visual Studio获取文件夹中的dll：

C：\ Program Files（x86）\ Microsoft Visual Studio 9.0 \ ReportViewer \ Microsoft.ReportViewer.WebForms.dll

我删除了引用并使用浏览器菜单再次添加并在文件夹

中选择了dll

C：\ Program Files（x86）\ Microsoft Visual Studio 12.0 \ ReportViewer \ Microsoft.ReportViewer.WebForms.dll

但现在问题出在下一行：

Warning[] warnings;
string[] streamids;
string mineType = "";
string encoding = "";
string extension = "";

byte[] bytePDF = reportViewer.LocalReport.Render("Pdf", null , out mineType, out encoding, out extension, out streamids, out warnings);

错误：

异常：抛出：“尚未指定运行报告所需的一个或多个参数。” （Microsoft.ReportingServices.ReportProcessing.ReportProcessingException）抛出了Microsoft.ReportingServices.ReportProcessing.ReportProcessingException：“尚未指定运行报告所需的一个或多个参数。” 时间：22/09/2014 14:59:58 螺纹：[4236]

Answer 2

使用名称添加参数＆＃34;名称＆＃34;和＆＃34;测试＆＃34;在您的报告中重试。

如果已经完成，请尝试更改

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

要：

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

您还可以尝试以下操作：Uncheck＆＃34;名称＆＃34;的Internal属性参数。

检查报告中参数的属性。（右键单击报告窗格，选择“参数”。）

UNCHECK - internal -

Answer 3

我解决了这个问题。

发生在我的报告中，因为我在测试中放置了两个参数，而我只是将数据传递给其中一个参数。

在我的报告中创建了“名称”和“测试”参数，我只是传递了“名称”的值。

listReportParameter.Add (new ReportParameter ("Name", this.textBox1.Text));

当我删除报告中的“测试”参数时，它有效。

由于

传递参数报告c＃
