我发现了错误

client found response content type of '' but expected 'text xml' The request failed with an empty response.
当我尝试执行以下代码时

//create a PDF from the SQL report
ReportViewer rview = new ReportViewer();

rview.ServerReport.ReportServerUrl = new Uri("http://server/ReportServer$MSSQL2K5?");

List<ReportParameter> paramList = new List<ReportParameter>();
paramList.Add(new Microsoft.Reporting.WinForms.ReportParameter("Batch", "1"));
paramList.Add(new Microsoft.Reporting.WinForms.ReportParameter("InvoiceNo", "0"));
rview.ServerReport.ReportPath = "Report/Report Invoice";

rview.ServerReport.SetParameters(paramList);

string mimeType, encoding, extension, deviceInfo;
string[] streamids;
Microsoft.Reporting.WinForms.Warning[] warnings;
string format = "PDF"; //Desired format goes here (PDF, Excel, or Image)             

deviceInfo =
"<DeviceInfo>" +
"<SimplePageHeaders>True</SimplePageHeaders>" +
"</DeviceInfo>";

byte[] bytes = rview.LocalReport.Render(format, deviceInfo, out mimeType, out encoding, out extension, out streamids, out warnings);
地址正确,因为我可以通过web浏览器加载报告:

this.webBrowser1.Navigate("http://server/ReportServer$MSSQL2K5?/Report/Report Invoice&Batch=1&InvoiceNo=0");

我需要用报表查看器加载报表,以便可以导出为PDF格式

尝试将Uri设置为完整服务Uri,例如:

new Uri("http://server/ReportServer$MSSQL2K5/reportservice2005.asmx?")

此外,是否需要尾随的
?我不确定,但是如果
SetParameters
需要的话,它不会被追加吗?

在我的情况下,这个错误是由SSRS服务器的硬盘空间不足引起的。

在我这边,服务(SSRS)挂在服务器端,必须强制停止服务并重新启动它。

我尝试了你的建议,但效果不太好,但是rview.ServerReport.ReportServerUrl=new-Uri(“);非常好!谢谢你的帮助!
new Uri("http://server/ReportServer$MSSQL2K5/reportservice2005.asmx?")
