如何将std_string.i与swig c++；到c# 我尝试执行SWIG将C++代码转换成C语言。 我让教程代码如下。 在构建步骤中，它未能构建。 我认为这不包括财产

我怎样才能把它包括进去

下面的代码是我的教程代码

例如，我

%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);

错误消息如下所示

example_wrap.c:292:18: error: expected ‘=’ before ‘;’ token
   namespace arg1 ;
                  ^
