title: Can I use class/function in C# file in App_Code besides the CodeFile for an asp.net website?
body: <p>In an asp.net website, we can create a "CodeFile" for each .aspx file. which contains a C# partial class. And this .aspx web can activate functions like </p>
  
  <pre><code>protected void Create_Click(object sender, EventArgs e)
  </code></pre>
  
  <p>in this CodeFile for clicking a button. </p>
  
  <p>I have another C# project, which has about 20 C# files. What I`m doing now is call the .exe of the project to do some processing. I was wondering is it possible that I can put the 20 C# files in the App_Code folder (or any other folder); then in the codeFile, call the functions inside all the C# files to do the processing instead using a compiled .exe file in my website?</p>
  
  <p>All the 20 C# files is in namespace xx, at least they have </p>
  
  <pre><code>namespace xx
  {
      class example1
      {
  </code></pre>
  
  <p>in every files. and I have have a "using xx" in the Codefile. The VS2012 can find the namespace, but the intellicense cannot pickup the class or functions in my C# project. So I was wondering if it`s doable or not.</p>
