c++ CStdioFile::WriteString 给出不正确的文件输出

Question

下面的代码片段会导致错误的结果:

void CTesterDlg::OnClickedButtonTest()
{
  CStdioFile  myfile;
  CString strLine1;
  CString strLine2;
  myfile.Open(_T("D:\Test1.csv"), CFile::modeWrite | CFile::modeCreate);
  strLine1 = L"01001,01001,2017-09-22,09:38:18.6,Alarm,STEERING PORT A – NO DATA RECEIVED,,,,0.0,Normal,0,1,0, ,127,0\n";
  strLine2 = L"Monkey, Animal\n";
  myfile.WriteString(strLine2);
  myfile.WriteString(strLine1);
  myfile.WriteString(strLine2);

  myfile.Close();
}

查看 Test1.csv 文件时

Monkey, Animal
01001,01001,2017-09-22,09:38:18.6,Alarm,STEERING PORT A
Monkey, Animal

strLine1 之后的所有内容

"..PORT A" " – NO> DATA RECEIVED,,,,0.0,Normal,0,1,0, ,127,0\n"

被删除了？欢迎任何想法。

您遇到了字符串编码问题。请注意，源代码中的 – 是破折号(Unicode 代码点 U+2013)，而不是连字符-减号。将其更改为连字符减号(Unicode 代码点 U+002D)，您的文本应显示在输出文件中。
