本文详细介绍了如何解决在C#环境下使用IronPython时遇到的导入错误问题，特别是当尝试使用xmlrpclib模块时出现的ImportError：未找到模块。通过查找IronPython的搜索路径、保存这些路径并在C#代码中加入所有路径，可以确保IronPython在尝试导入缺失库时进行正确的搜索。

I was using IronPython to execute python code inside my C# implementation lately, and I encountered this error when trying to use xmlrpclib:

  
    ImportError: No module named xmlrpclib.

It was really frustrating because if I try the same in IronPython console, it works fine. It turned out that this was a problem with search paths. When called via C# code, IronPython does not search for missing libraries unless you provide it a path to search for. Here’s how I solved this issue:

First, find out the search paths that IronPython is using in console mode:

import sys
print sys.path

This will print all the search paths. Save these paths somewhere.

Now include all these search paths inside your C# code:

ScriptEngine Engine = Python.CreateEngine();
ICollection<string> Paths = Engine.GetSearchPaths();
Paths.Add("<Path>");
Engine.SetSearchPaths(Paths);

Replace <Path> with the path you saved earlier. Now IronPython will search all these pathsbefore failing with an ImportError.
