您可以看到我正在创建一个新线程,该线程正在启动一个Python shell,但没有返回Python输出。我该如何修复它呢?

当然可以看看,它几乎肯定会满足您的需求

比如说

using System;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;
// we get access to Action and Func on .Net 2.0
using Microsoft.Scripting.Utils;

namespace TestCallIronPython
{
    class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
            ScriptEngine pyEngine = Python.CreateEngine();
            ScriptScope pyScope = pyEngine.CreateScope();
            pyScope.SetVariable("test", "test me");

            string code = @"
             print 'test = ' + test
             class MyClass:
             def __init__(self):
               pass

             def somemethod(self):
               print 'in some method'

             def isodd(self, n):
               return 1 == n&nbsp;% 2
           ";
           ScriptSource source = pyEngine.CreateScriptSourceFromString(code);
           CompiledCode compiled = source.Compile();
           compiled.Execute(pyScope);

           // Get the Python Class
           object MyClass = pyEngine.Operations.Invoke(pyScope.GetVariable("MyClass"));
           // Invoke a method of the class
           pyEngine.Operations.InvokeMember(MyClass, "somemethod", new object[0]);

           // create a callable function to 'somemethod'
           Action SomeMethod2 = pyEngine.Operations.GetMember&lt;Action&gt;(MyClass, "somemethod");
           SomeMethod2();

           // create a callable function to 'isodd'
           Func&lt;int, bool&gt; IsOdd = pyEngine.Operations.GetMember&lt;Func&lt;int, bool&gt;&gt;(MyClass, "isodd");
           Console.WriteLine(IsOdd(1).ToString());
           Console.WriteLine(IsOdd(2).ToString());

           Console.Write("Press any key to continue . . . ");
           Console.ReadKey(true);
       }
   }
}

直接取自示例。

请小心,您应该确保流程实际启动,为此,您应该检查方法启动的结果。如果进程启动,则返回true,否则返回false。

是否考虑使用?
