            //请问这里怎么调用，这里是一个batton把。我想调用convert函数实现，doc转换pdf格式
              路径写死 本人c#新手，换忘高手多多指点，另外 c#就一个cs文件把？和以前的c++不一样吧，c++ 有.cpp .h
             文件。那c#如何包含其他cs文件内容呢？不需要头文件?
        }
    }
}

Answer 1

RemoteConverter RC = new RemoteConverter();//创建类的实例
bool result = RC.convert(string source, string output);
result 即为结果了

Answer 2

RemoteConverter con = new RemoteConverter();
con.convert("c:\\1.cod","c:\\1.pdf");
