Programmatically determine the directory where ASP.NET stores temporary files

Today in the forums, I came across an interesting question. The user wanted to know if it was programmatically possible to determine where ASP.NET stored its temporary files.

The answer is yes and it’s done using the HttpRuntime.CodegenDir Property

C#

protected void Page_Load(object sender, EventArgs e)
{
    Response.Write(HttpRuntime.CodegenDir);
}

VB.NET

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    Response.Write(HttpRuntime.CodegenDir)
End Sub

Running this on my machine, I get the following output

C:\Users\Suprotim\AppData\Local\Temp\Temporary ASP.NET Files\SampleProjects\e2b93d07\cc8b1498
