Question

wchar_t OrderingCode[100];

api的一些代码

string looks like this L"AAAA-1-3-5-5\n\r\BBB-A-3-6-6-4"

我需要在换行符中将字符串拆分为2。我只在ppl循环数组时找到样本。任何api函数都可以在C＃

中用作String.Split

m_Result.SetWindowTextW(OrderingCode1);
m_Result.SetWindowTextW(OrderingCode2);

Answer 1

使用std::string然后您可以轻松地按如下方式拆分它：

std::vector< std::wstring > SplitString( const std::wstring& str, wchar_t ch )
{
    std::vector< std::wstring > ret;
    size_t startPos = 0;
    size_t endPos = str.find( ch, startPos );
    while( endPos != std::wstring::npos )
    {
        ret.push_back( str.substr( startPos, endPos ) );
        startPos = endPos + 1;
        endPos = str.find( ch, startPos );
    }
    ret.push_back( str.substr( startPos, str.length() );
    return ret;
}

Answer 2

    wchar_t * test, *next_token1;
    test = wcstok_s(OrderingCode, L"\n\r", &next_token1);
    if (test != NULL)
    {
      m_Result.SetWindowTextW(test);
      test = wcstok_s(nullptr, L"\n\r", &next_token1);
      if (test != NULL)
      {
        m_Result2.SetWindowTextW(test);
      }          
    }

C拆分了一个wchar_t数组
