托管dll中找不到入口点

您要执行的操作是P/Invoke. (请阅读我对Abhinav答案的评论；希望我理解您的问题.如果这是关于在非托管代码中使用托管程序集的话，我也知道更好的答案.)

您需要将static extern声明与System.Runtime.InteropServices.DllImportAttribute一起使用.请参阅 http://msdn.microsoft.com/en-us/library/system .runtime.interopservices.dllimportattribute.aspx [ ^ ]和一些代码示例.

实际上，根据要公开的方法，P/Invoke可能很容易，也可能非常困难.您需要考虑许多细节:调用约定，针对不同类型的封送处理，参数传递的不同方法等等.

What you trying to do is P/Invoke. (Read my comment to the answer by Abhinav; I hope I understand your question. If this is about using managed assembly in unmanaged code, I also know better answer.)

You need to use static extern declaration with System.Runtime.InteropServices.DllImportAttribute. See http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.dllimportattribute.aspx[^] with some code sample.

Actually, P/Invoke can be easy or extremely difficult, depending on methods you want to expose. There are many details you need to take into account: calling conventions, marshaling for different types, different methods of parameter passing and more.

您不能在非托管代码中直接使用托管dll.
您需要围绕托管dll构建COM可调用包装器，然后将其添加为对非托管代码的引用.

在 COM可调用包装 [

You cannot directly use a managed dll in unmanaged code.
You need to build a COM callable wrapper around the managed dll and then add this as reference to your unmanaged code.
