In this method the long atribute is a reference to a string which by the way is a ip adress of a machine. I cannot change the c api, so how can I in c#, get the pointer of such string and pass it to the function? I have already tried marshalling and all that stuff but nothing...
<cstring> 在C++标准化过程中,C++为了向前兼容C语言,标准化组织将所有C语言的头文件都进行了新的定义,加入到了标准库中,加入后的文件名就新增了一个"c"前缀并且去掉了.h的后缀名,所以<string.h>头文件成了头文件,其实现是相同的或是兼容以前的。要注意,此时的依然不是对应着string数据类型,仍然是字符数组char...

The String class provides methods for dealing with Unicode code points (i.e., characters), in addition to those for dealing with Unicode code units (i.e., char values). 除非另有说明,否则将null参数传递给String类中的构造函数或方法将引发NullPointerException。 String类采用UTF-16编码格式来表示一...
