C# 可以序列化C代码块吗？

我在用C#with 3.5。是否可以序列化一段代码，将它传输到某个地方，反序列化它，然后执行它

这种用法的一个示例是：

Action<object> pauxPublish = delegate(object o)
{
    if (!(o is string))
    {
        return;
    }
    Console.WriteLine(o.ToString());
};
Transmitter.Send(pauxPublish);

---

我的最终目标是能够在不同的进程中执行任意代码（事先不知道代码）。

将其编译成单独的程序集，发送程序集，让其他进程加载它

您可能需要考虑安全性问题。

更新：另一个想法是生成表达式树并使用此库对其进行序列化：

---

您也可以将其作为字符串发送，然后使用CodeDomProvider对其进行编译，结果相同。我有一段代码示例，如下所示：
