c# Writing to system temp folder?

One of my boss's hosting clients is coming up with an issue on his site. It seems that whatever web service they are using is causing a permissions issue. I think they get a list, and export it to XML, and this is where the errors occur.

Can someone point me in the right direction to look through their code? I don't know C# at all, so any reference to where I should begin looking would help...

What is the error?

this is the exact error:

System.InvalidOperationException: Unable to generate a temporary class (result=1).
error CS2001: Source file 'C:\WINDOWS\TEMP\4ir2ueu-.0.cs' could not be found

Ok. So...how/where/what would I look for in the code to prevent this from trying to dump this file in C:\WINDOWS\TEMP

JimBrandley

If you look at the call stack, it appears that there is no user code invoked yet. Try granting write permission to that directory.

can't do it. Too much of a security risk invloved in letting the users have that kind of access.

There must be something in the code that we can change that will write the file to a different directory rather than the windows\temp directory

JimBrandley

I have not been able to locate a way to do that. Leave the question open for a while, and maybe someone else will see it who knows of a way.

I'm going to email another expert asking him to take a peek at this one....

Hi kevp75

Consider using Isolated storage:

for some reason I kind of doubt the host would be willing to do that, however I will mention it to him.

So am I to assume that there is nothing code wise to specify the path where this temporary file will be stored?
