比较类型char *和wchar_t *的C字符串 [英] Compare C-string of types char* and wchar_t*

问题描述

我有一个key，例如:

wchar_t key[] = L"764frtfg88fgt320nolmo098vfr"; 

和数据库查询返回的char* row[i].

我想将我的Key与row[i]进行比较.我尝试过

I'd like to compare my Key with row[i]. I tried with

wcscmp (key,row[i]) != 0)

但是它给了我一个错误.有什么建议吗?

but it gives me an error. Any suggestions ?

推荐答案

这可能会有所帮助:摘要:

#include <string>

wchar_t Key[] = L"764frtfg88fgt320nolmo098vfr";
std::wstring k(Key);

const char* text = "test"; // your row[i]
std::string t(text);
// only works well if the string being converted contains only ASCII characters.
std::wstring a(t.begin(), t.end()); 

if(a.compare(k) == 0)
{   
    std::cout << "same" << std::endl;
}
