Unicode字符串无法正常工作 [英] Unicode string not working as expected

问题描述

我有一个C ++程序(gpc程序裁剪器)和一个vb包装器.

我有一个问题.当我用"file.out"调用fopen时
因为string.fopen得到的是单词而不是字节的集合，并且感觉我只给出了1个字符，后跟一个空值.

如何管理cstyle字符串?

在vb.net中:
使用vb.net(dotnet)字符串(16位unicode)到预期8位字节字符串的c函数时出现问题
私有声明自动功能fopen Lib msvcr100.dll(ByVal fn作为字符串，ByVal模式作为字符串)作为IntPtr

I have a C++ program(the gpc program clipper) and a vb wrapper for it.

I have one problem in it. When i call fopen with a "file.out"
as string.fopen gets a collection of words instead of bytes and feels that I gave only 1 char followed by a null.

How do I manage to send a cstyle string?

in vb.net:
problem using vb.net(dotnet) string(16 bit unicode) to a c function expecting 8 bit byte string
Private Declare Auto Function fopen Lib msvcr100.dll (ByVal fn As String, ByVal mode As String) As IntPtr

推荐答案

在旧" vb中，您将使用StrConv.在VB.NET中，您应该使用Encoding类.请查看下面的链接.

祝你好运！

In "old" vb you would use StrConv. In VB.NET you should use the Encoding class. Have look at the link below.

Good luck!

我通过在fopen的Declare语句中将Ansi替换为Auto来管理它.

I managed it by replacing Auto by Ansi in the Declare statement for fopen.
