如何调用C＃中的托管DLL文件？ [英] How to call a Managed DLL File in C#?

问题描述

我正在制作一种脚本语言，但我有一个严重的问题。

我需要这样做，所以你可以使用语言调用.NET DLL，但是我没有找到在C＃中没有办法。

有没有人知道如何以编程方式加载和调用.NET DLL？ （我不能只是添加引用，所以不要这样说）

解决方案

这是我做的：

  Assembly assembly = Assembly.LoadFrom（assemblyName）; 
 System.Type type = assembly.GetType（typeName）; 
 Object o = Activator.CreateInstance（type）; 
 IYourType yourObj =（o as IYourType）; 
  

其中 assemblyName 和 typeName 是字符串，例如：

  string assemblyName = @C：\foo\\ \\yourDLL.dll; 
 string typeName =YourCompany.YourProject.YourClass; //完全限定类型名称
  

那么你可以调用obj上的方法：

  yourObj.DoSomething（someParameter）; 
  

当然，您可以调用哪些方法由界面定义 IYourType ...

I am making a scripting language but I have a serious problem.

I need to make it so you can call .NET DLLs in the language but I have found no way to do this in C#.

Does any one know how can I load and call a .NET dll programmatically? (I can not just Add reference so don't say that)

解决方案

Here's how I did it:

Assembly assembly = Assembly.LoadFrom(assemblyName);
System.Type type = assembly.GetType(typeName);
Object o = Activator.CreateInstance(type);
IYourType yourObj = (o as IYourType);

where assemblyName and typeName are strings, for example:

string assemblyName = @"C:\foo\yourDLL.dll";
string typeName = "YourCompany.YourProject.YourClass";//a fully qualified type name

then you can call methods on your obj:

yourObj.DoSomething(someParameter);

Of course, what methods you can call is defined by your interface IYourType...
