Get ASP.NET temporary folder path

From my C# code, that doesn't run from within IIS/ASP.NET, I need to add a user account permissions to the ASP.NET temp folder. (It is required while adding my site to IIS.) The folder on my local system is:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files

I'd hate to hard-code this path into my code, so I was wondering if I can retrieve it from .NET framework itself?

Simplest way with validation:

if (file.ContentLength > 0)
{
    string temp = Path.GetTempPath();

    var path = Path.Combine(temp, fileName);
    file.SaveAs(path);
}

and in web.config:

<system.web>
  <compilation tempDirectory="D:\MyTempFiles" />
</system.web>

Try System.Web.HttpRuntime.CodegenDir to get the physical path of directory where the ASP.NET temporary files are stored for the current application.

Hmm. I didn't know that it would be so complicated. For the lack of better answer, I was able to come up with something like this:

using System.Runtime.InteropServices;

string net_base = Path.GetFullPath(Path.Combine(RuntimeEnvironment.GetRuntimeDirectory(), @"..\.."));
string strTemp32 = string.Concat(net_base, @"\Framework\", RuntimeEnvironment.GetSystemVersion(), @"\Temporary ASP.NET Files");
string strTemp64 = string.Concat(net_base, @"\Framework64\", RuntimeEnvironment.GetSystemVersion(), @"\Temporary ASP.NET Files");

There're obviously two temp folders -- for 32-bit and 64-bit processes. It is based on this sample, and also relies on the assumption that default ASP.NET temporary folders are hard-coded.

Correct me, if you find a better way?

I think this should help...

There is a section in web.config/machine.config under the compilation tag where the path is set by default. Here are the attributes of the section...

Much more safe will be if you use your own temporary folder in for example App_Data

Unfortunately Path.GetTempPath(); won't return this folder because it is asp.net internal folder.

The good news is that you can change it specifing the file location in web.config with element.
