[英]Generate C# Interface from C++ using SWIG
How do I use SWIG to generate a C# interface (or at least a C# mock-able base class) from C++ using SWIG? 如何使用SWIG从C ++使用SWIG生成C#接口(或至少是C#模拟基类)?
Given: 鉴于:
C++: C ++:
class IWidget
{
public:
virtual void Flob() = 0;
};
class Widget : public IWidget
{
public:
void Flob() {};
};
I would like to output C#: 我想输出C#:
public interface IWidget
{
void Flob();
}
public class Widget : IWidget
{...}
Note: Solution does not have to be an interface, but I do need to be able to use mocking frameworks such as Moq or Rhino.Mocks to mock out the base of the C# Widget class. 注意:解决方案不一定是接口,但我需要能够使用模拟框架(如Moq或Rhino.Mocks)来模拟C#Widget类的基础。 My attempts only yielded generated C# with no public constructors.
我的尝试只产生了没有公共构造函数的生成的C#。
You may be able to get the output you list by using one or more of: 您可以使用以下一项或多项来获取列出的输出:
csclassmodifiers
%ignore
on the pure virtual methods, add necessary method declarations using cscode . %ignore
,使用cscode添加必要的方法声明。 csinterfaces typemap
csinterfaces_derived typemap
However this may not be the easiest way to achieve the goal of making your class mockable. 但是,这可能不是实现使您的类可模拟的目标的最简单方法。 Consider extending your post to clearly identify what is the c# that you need to achieve this if
interface
is not used. 考虑扩展您的帖子以清楚地标识如果不使用
interface
,您需要实现此目的的c#。

Sorry I can't provide an actual code answer, hopefully the above gets you there. 对不起,我无法提供实际的代码答案,希望上面的内容可以帮助您。
Start with the 从...开始
"Interface file" and then "Building a C# module" are the imp things there. “接口文件”然后“构建一个C#模块”就是那里的东西。 Below is mentioned for compile/link in the same document.
下面提到了同一文档中的编译/链接。 Do the same in Visual Studio.
在Visual Studio中执行相同的操作。
$ swig -csharp example.i
$ gcc -c -fpic example.c example_wrap.c
$ gcc -shared example.o example_wrap.o -o libexample.so
$ cscc -o runme *.cs
