Crystal Report"文件名无效".问题

Question

我上传了我的WebApplication.我的应用程序是在带有Crystal Reports 2008 sp3的VS2008中.我上传了并行plex服务器.我在Bin文件夹中添加了所有必需的Crystal报表.我的报告路径也是正确的.

我收到的错误是

Line 41:         ReportDocument myreport = new ReportDocument();
Line 42:         string reportPath = Server.MapPath("~/CrystalReport.rpt");
Line 43:         myreport.Load(reportPath);
Line 44: 
Line 45:         myreport.SetDataSource(ds);

   System.Web.UI.Control.LoadRecursive() +50
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627

我无法得到错误的位置..报告位于根文件夹本身.那么这个问题是什么呢？还有一个文件夹aspnet_client.那是我们需要做的吗？

请等待回复

同样的问题让我头疼了很长一段时间.现在我找到了答案:)

转到c:\windows\temp 文件夹及其properties->security 添加新用户" IIS_IUSRS"并赋予其完整/读写能力.

它解决了我的问题.

希望它也适合你:)
