系统找不到指定的路径。

这只是意味着你用来引用路径的路径不正确。



或者，直接使用绝对路径或使用正确的相对路径。您需要确保路径正确，以便找到并使用该文件。



对于相对路径，您可以尝试此提示并正确解析路径设置文件的来源：解决多文件夹中的路径网站 [ ^ ]

Hi,
I have build a web project with a crystal report. when i run that project using visual studio 2008 it run properly..

But when I deploy it on IIS and run it using IP address it gives following Error..

CrystalDecisions.Shared.CrystalReportsException: Load report failed. ---> System.Runtime.InteropServices.COMException: The system cannot find the path specified. at CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass.Open(Object& DocumentPath, Int32 Options) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.Open(Object& DocumentPath, Int32 Options) at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened() --- End of inner exception stack trace --- at CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper.EnsureDocumentIsOpened() at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename, OpenReportMethod openMethod, Int16 parentJob) at CrystalDecisions.CrystalReports.Engine.ReportDocument.Load(String filename) at Default2.TreeView1_SelectedNodeChanged(Object sender, EventArgs e) in c:\Inetpub\wwwroot\erp_web\Default2.aspx.cs:line 154

and also full permission to access drive c:..

What is solution?? Please suggest me.

解决方案

The system cannot find the path specified.
This simply means that the path is incorrect that you are using to refer the path.

Either, use a absolute path directly OR use a correct relative path. You would need to make sure that the path is correct such that file is found and used.

For relative path, you can try this Tip and resolve the path correctly before setting the source of the file: Resolving Paths in a Multi-Folder WebSite[^]
