System.Diagnostics.Process.Start不适用于IIS，但在ASP.NET开发服务器上

Question

I am using VS2008 C# and testing on my local XP Pro PC with local IIS, I have wrote a web service to call a third party software .exe file to use svn checkout commands to insert data into a folder, which use System.Diagnostics.Process.Start . The same codes did work when I use VS2008 build-in ASP.NET Development Server( http://localhost:2999/MyServices/MyServices.asmx ). but when I use IIS normal URL( http://developer/MyServices/MyServices.asmx ) to run Process.Start on the web service, it just haunlted and not doing anything.plz send one sample program.

Answer 1

This is most likely down to the user being used to run the code. When using the built-in server, it is running as the same user as Visual Studio is running as. When in IIS, it will be running as the MACHINENAME\\ASPNET user.

If the process you are starting cannot execute as the MACHINENAME\\ASPNET user, it will not work when hosted in IIS unless you change your configuration to change the user it runs as. See this page for more info on what users are used for what in IIS.
