解决方案
我建议您为函数编写一些非常简单的测试数据。在C ++代码中尝试查看结果，而不是轻松调试问题所在的C＃。
另一个有用的提示是你使用TRACE宏进行调试输出，看看发生了什么。
一个常见问题是字节大小是字符串长度的两倍。比你需要转换字符串。看一下有关编码和Bitconverter 。
bool CRegeditExport::ExportBinaryValue( IN const LPBYTE lpBinValue, IN const DWORD nBinValueSize, IN const BYTE nRegType, IN CString strValueName, OUT CString &strRetVal)
{
//binary is somewhat different
//we also have to keep 80 chars per line limit char including the value name
/*
if a value name is very long then it is terminated after the first byte is written

I would suggest that you write some very simple test data for your funtions. Try it in your C++ code to see the results, than you can easy debug the C# where the problems are.
Another helpful tip is that you make debug output like with TRACE macro to see what is going on.
One common issue is that the byte size is double than the string length. Than you need to convert strings. Take a look at these articles about encoding and Bitconverter.
这篇关于在C＃中转换以下代码C ++代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
