c# - 如何将 std_string.i 与 swig c++ 包含到 c#

Question

我尝试执行 swig 将 c++ 代码转换为 c#。我使教程代码遵循swig-tutorial。在构建步骤中，它无法构建。我认为它不包括在内。

我怎样才能包括它？

以下代码是我的教程代码。

例子.i

%module example
%include <std_string.i>
%{

using namespace std;
int my_mod(int x, int y);
string getstring(string str);
%}
int my_mod(int x, int y);
string getstring(string str);

例子.cpp

#include <string>
using namespace std;
 double My_variable = 3.0;

 int my_mod(int x, int y) {
     return (x%y);
 }

 string getstring(string str)
 {
     return str+" mine";
 }

运行me.cs

using System;
 public class runme {
     static void Main() {
//         Console.WriteLine(example.My_variable);
//         Console.WriteLine(example.fact(5));
         int i =example.my_mod(10,3);
         Console.WriteLine("result " + i);
         Console.WriteLine(example.getstring("mygirl"));
     }
 }

如下所示的错误消息。

example_wrap.c: In function ‘void CSharp_std_set(void*)’:

   namespace arg1 ;
