为什么DllImport不能与"__Internal"一起使用? [英] Why DllImport doesnt work with "__Internal"?

问题描述

我有C ++共享库，可以为Linux和Windows导出方法int MyFunc().

I have C++ shared library which export method int MyFunc() for both Linux and Windows.

从C#中，我确实使用以下签名调用MyFunc.

From C# I do call the MyFunc with following signature.

[DllImport(@"__Internal", CharSet = CharSet.Ansi, EntryPoint = "MyFunc")]
static extern unsafe int MyFunc();
// Later I'm using :
MyFunc();

此代码在Windows上工作正常，但在linux内部会抛出异常EntryPointNotFound.

This code works fine on windows but inside linux this throw an exception EntryPointNotFound.

我用-rdynamic选项编译了我的C ++库，我可以看到MyFunc被导出为带有nm的D标志，但这也无济于事.

I have compiled my C++ library with -rdynamic option and I can see MyFunc is exported as D flag with nm but this also didn't help me.

如果我只是将DllImport(@"__Internal"更改为DllImport(@"mys.so"而没有任何更改，则可以在linux上正常工作，但随后我必须在Windows中使用DllImport(@"mys.dll"，这会破坏代码的跨兼容功能.
所以我想避免这种情况.

Without any change if I simply change DllImport(@"__Internal" to DllImport(@"mys.so" then will work fine on linux but then I have to use DllImport(@"mys.dll" in windows which this breaks code cross compatible feature.
So I want to avoid this.

我没有看到为什么__Internal在Linux上无法运行的任何错误.
请注意，我正在使用单声道.

I don't see any mistake that why __Internal isn't working on Linux.
Note that I'm using mono.

有人知道为什么在Linux上不起作用吗?

Any idea why this is not working on Linux ?

推荐答案

您可以在Windows和Linux上使用它:

You can use this on both windows and linux:

[DllImport ("mys")]

将根据平台添加适当的扩展名(这对.NET和mono均适用).

The appropriate extension will be added according to the platform (and this works on both .NET and mono).
