C# 如何从进程中检索代码然后运行它

在C#中检索并执行进程中的代码

csharp
using System;
using System.Reflection;
class CodeRetrieval
{
    public static string RetrieveCodeFromProcess(int processId)
    {
        try
        {
            AppDomain targetDomain = AppDomain.CreateDomain("TargetDomain");
            // 在目标域中加载程序集
            Assembly assembly = targetDomain.Load("YourAssemblyName");
            // 在加载的程序集中查找并获取代码
            // 这里假设目标代码是一个字符串
            Type targetType = assembly.GetType("YourTargetType");
            MethodInfo method = targetType.GetMethod("YourMethod");
            string code = (string)method.Invoke(null, null);
            // 卸载目标域
            AppDomain.Unload(targetDomain);
            return code;
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error retrieving code: " + ex.Message);
            return null;
        }
    }
}

csharp
using System;
using Microsoft.CSharp;

                    Console.WriteLine(error.ErrorText);
                }
            }
        }

        {
            Console.WriteLine("Error executing code: " + ex.Message);
        }
    }
}

csharp
class Program
{
    static void Main()
    {
        int targetProcessId = 1234; // 替换为目标进程的实际ID
        // 步骤1: 从进程中检索代码
        string retrievedCode = CodeRetrieval.RetrieveCodeFromProcess(targetProcessId);
        if (retrievedCode != null)
