C# dll

namespace PoemDLL
{
    public class Poetry
    {
        public void PrintSuShiPoem()
        {

            string strSS =  "休对故人思故国，且将新火试新茶。诗酒趁年华。";

            Console.WriteLine(strSS);
        }

        public static void PrintNlxdPoem()
        {
            string strNlxd = " 人生若只如初见，"
                + "何事秋风悲画扇。"
                + "等闲变却故人心，"
                + "却道故人心易变。"
                + "骊山语罢清宵半，"
                + "泪雨霖铃终不怨。"
                + "何如薄幸锦衣郎，"
                + "比翼连枝当日愿。";

            Console.WriteLine(strNlxd);
        }

        public static int UnityAdd(int a, int b)
        {
            int c = a + b;
            return c;
        }

        public static void WritePoem(char[] strs_poem)
        {
            String str_poem = "不应有恨，何事长向别时圆？"
                                         + "人有悲欢离合，月有阴晴圆缺，此事古难全。"
                                         +" 但愿人长久，千里共婵娟。";

            char[] str = str_poem.ToCharArray();
            int len = str_poem.Length;
            Buffer.BlockCopy(str, 0, strs_poem, 0, len * 2);
        }

        public static string PythonPoem()
        {

            String str_poem = "不应有恨，何事长向别时圆？"
                             + "人有悲欢离合，月有阴晴圆缺，此事古难全。"
                             + " 但愿人长久，千里共婵娟。";

            return str_poem;
        }

        public static void PythonPoem(string poet)
        {
            poet = "SuDongPo";
            String str_poem = poet;

            return ;
        }

    }
}

python 调用

import clr
import sys

sys.path.append("F:\VS2013Buffer\HelloVS\ActivatePoemDll")
clr.FindAssembly("PoemDLL .dll")
from PoemDLL import *    # 导入命名空间

Poetry.PrintNlxdPoem()
instance = Poetry() #class1是dll里面的类
instance.PrintSuShiPoem() #显示一个窗口


poem = "kkkkkkkkkkkkllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll"
Poetry.WritePoem(poem)
print(poem)

输出

有一问题是怎么在把python的变量值通过参数来修改？上面poem的值就没有修改为什么呢？没想明白？
