Is <code>DotNet4Class.dll</code> built against .NET 4? I assume so based on the naming of the dll.

Note the issue here: <a href="http://sourceforge.net/tracker/?func=detail&amp;aid=3293169&amp;group_id=162464&amp;atid=823891" rel="noreferrer">http://sourceforge.net/tracker/?func=detail&amp;aid=3293169&amp;group_id=162464&amp;atid=823891</a>

<blockquote>
 clr.AddReference fails when assembly is built with .NET 4.0 - ID: 3293169
</blockquote>

I'd read the solution, but essentially, you need to rebuild and recompile the python for .NET project under .NET 4.

I'll also mention that projects like this, that aren't actively developed and used by lots of people, generally have subtle idiosyncrasies that make knowledge of the platform essential to work around problems such as this. It sounds like you're trying to hack this solution in without understanding much about python or .NET which is always going to be fraught with problems.

blocks|key|3793166|text|一个原因可能是Windows没有允许它从“外部源”加载。要解决此问题，请执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3793167|3793168|右键单击.dll|unordered-list-item|3793169|"Properties"|3793170|Under“常规”，然后单击"Unblock"|3793171|3793172|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|N|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|O|8|@]|9|@]|A|$]]|$1|F|3|G|5|E|7|P|8|@]|9|@]|A|$]]|$1|H|3|I|5|E|7|Q|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|L|$]]

One reason can be Windows was not enabling it to load from "external sources". To fix this:

What worked for me was to Unblock the dll file.
if u download the dll file or took it from different computer it might be blocked. So unblocked solved the issue for me.
To unblock right click on the properties if the dll file and check the Unblock box at the bottom

I'm using CPython and I have a C# dll. I'm trying to use Python for .NET to make them talk. I can't use IronPython because I need to integrate this into an existing CPython system.

I'm completely new to Python for .NET, and I actually have very little experience with Python and no experience with C#. So please forgive me if my question seems very basic.

I'm using Python 2.7.3, and I downloaded
pythonnet-2.0-alpha2-clr2.0_131_py27_UCS2 and unzipped it into a folder named pyfornet_test, which also contains the dll I'm trying to use (called DotNet4Class.dll)

Then I run this:

<pre><code>import sys

import os

import clr

sys.path.append(r"C:\pyfornet_test")

clr.AddReference("DotNet4Class.dll")
</code></pre>

Which gives me this error:

<pre><code>System.IO.FileNotFoundException: Unable to find assembly 'DotNet4Class.dll'.
 at Python.Runtime.CLRModule.AddReference(String name) in C:\Users\Barton\Documents\Visual Studio 2008\Projects\PyShar
p\trunk\pythonnet\src\runtime\moduleobject.cs:line 375
</code></pre>

Any advice would be much appreciated. Thank you!
