WINCE 文本读写操作总结

1.C语言函数fopen(),式例代码：

 //author:firehood//data: 2011-5-19#include <stdio.h>#include <tchar.h>int _tmain(int argc, _TCHAR* argv[]){// 创建或打开二进制文件,并以追加方式打开FILE *pFile=_tfopen(_T("//NAND2//FileLog1.txt"), _T("wab+"));if(pFile){fwprintf(pFile, _T("%s/n"), _T("test1"));fwprintf(pFile, _T("%s/n"), _T("test2"));fwprintf(pFile, _T("%s/n"), _T("test3"));fclose(pFile);}// 读文件pFile=_tfopen(_T("//NAND2//FileLog1.txt"), _T("rb")); TCHAR str[20];if(pFile) { while(_ftscanf(pFile,_T("%s/n"),str)!=EOF){ _tprintf(_T("%s/n"),str);} fclose(pFile);}return 0;}

2.C++ fstream,式例代码：

//author:firehood//data: 2011-5-19#include <tchar.h>#include <fstream>#include <string>#include <iostream>using namespace std;int _tmain(int argc, _TCHAR* argv[]){fstream file;// 以追加方式打开文件，只写操作file.open("//NAND2//FileLog.txt", ios_base::out | ios_base::app);if(file.is_open()) {file << "test1" << endl;file << "test2" << endl;file << "test3" << endl;file.flush();file.close();}// 以只读方式打开文件file.open("//NAND2//FileLog.txt", ios_base::in);if(!file.is_open()) {cout << "Open file failed"<<endl;exit (1);}string str; while (!file.eof()){ // 获取一行数据getline(file,str);cout << str.c_str() << endl;}file.close();return 0;}

3.mfc CFile、CStdioFile类

//author:firehood//data: 2011-5-19#include <tchar.h>#include <afx.h>int _tmain(int argc, _TCHAR* argv[]){CStdioFile cFile;// 写文件if(!cFile.Open(_T("//NAND2//FileLog2.txt"),CFile::modeCreate | CFile::modeWrite | CFile::typeBinary)){printf("Create file failed../n");return false;}cFile.WriteString(L"test1");cFile.WriteString(L"test2");cFile.WriteString(L"test3");cFile.Close();// 读文件if(!cFile.Open(_T("//NAND2//FileLog2.txt"),CFile::modeRead | CFile::typeBinary)){printf("Open file failed../n");return false;}CString str; while(cFile.ReadString(str)){// 输出_tprintf(_T("%s/n"),str);}cFile.Close();return 0;}

CFile 写文件操作示例，支持ANSI、UNICODE中文输出。

//author:firehood//data: 2011-5-19#include <tchar.h>#include <afx.h>int _tmain(int argc, _TCHAR* argv[]){ CFile cFile;if(cFile.Open(_T("D://FileLog3.txt"),CFile::shareExclusive|CFile::modeCreate|CFile::modeWrite)){#ifdef _UNICODEULONGLONG dwFileLen = cFile.GetLength(); if (0 == dwFileLen) // 文件为空时写入UNICODE字节序标记 { const unsigned char LeadBytes[] = {0xff, 0xfe}; cFile.Write(LeadBytes, sizeof(LeadBytes)); }#endifTCHAR *str=_T("中文字符串");cFile.Write(str,_tcslen(str)*sizeof(TCHAR));cFile.Close();}else{printf("Create file failed/n");}return 0;}
