CFile 正常寫入中文

CFile myFile;
    BOOL isopen=myFile.Open(filename, CFile::modeReadWrite|CFile::modeCreate | CFile::typeBinary|CFile::shareDenyNone); 
    if(!isopen)
        AfxMessageBox("不能開啟檔案!");
    
    CFile myFile(); 
    CString EditContent; 
    m_EditText->GetWindowText(EditContent); 
    LPCTSTR str = EditContent.GetBuffer( EditContent.GetLength()); 
    myFile.Write(str,EditContent.GetLength()*sizeof(CHAR));
    myFile.Close();
 

例子：

#include <afx.h>
#include <iostream.h>
int main(){
	
	CString str1="中國\r\n";
	LPCTSTR s1=str1.GetBuffer(str1.GetLength());

	CString str3="五湖四海\r\n";
	LPCTSTR s3=str3.GetBuffer(str3.GetLength());
	TRY 
	{
		CFile file("hello.txt",CFile::modeCreate|CFile::modeWrite|CFile::typeBinary);
		file.Write(s1,str1.GetLength()*sizeof(CHAR));
		file.Write(s2,str2.GetLength()*sizeof(CHAR));
		file.Write(s3,str3.GetLength()*sizeof(CHAR));
		file.Close();
	}
