[C++] 批量删除文件名多余的一个相同字符串

本文主要是介绍[C++] 批量删除文件名多余的一个相同字符串，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

使用C++方法：

// ++++++++

#include <string>
#include <io.h>
#include <iostream>
using namespace std;
bool change_name(const char* char_path,const char* char_del)
{string path="";string path_main="";string find_str="";path.append(char_path);find_str.append(char_del);cout<<"Now,you find file path is :"<<path.c_str()<<endl;path_main.append(path.c_str());path.append("/*.*");string path_old="";string path_new="";string file_name="";string find_result="";string temp_name="";string file_exe="";string file_pre="";_finddata_t file; bool bFind=false;bool bFile=false;long lf;  //输入文件夹路径  if((lf = _findfirst(path.c_str(), &file))==-1)  cout<<"Not Found!"<<endl;  else{  //输出文件名  cout<<"file name list:"<<endl;  while(_findnext( lf, &file)==0){  bFile =false;bFind =false;path_old="";path_new="";file_name="";find_result="";temp_name="";file_pre="";file_exe="";file_name.append(file.name);path_new.append(path_main.c_str());path_new.append("\\");if(file_name.find("..")!= string::npos){continue;}//cout<<file.name<<endl;  path_old.append(path_main.c_str());path_old.append("\\");path_old.append(file.name);//cout<<path_old.c_str()<<endl; int iPos_dot=0;iPos_dot =file_name.find_last_of(".");if(iPos_dot<=0){bFile =false;}else{bFile = true;}if(false == bFile){continue;}file_exe.append(file_name.substr(iPos_dot,file_name.length()));temp_name.append(file_name.substr(0,iPos_dot));int ilen = file_name.length();int ilen_find = temp_name.length() - find_str.length();if(temp_name.find(find_str) != string::npos){bFind=true;}if(ilen_find>0 && (true==bFind)){find_result.append(temp_name.substr(ilen_find,find_str.length()));file_pre.append(temp_name.substr(0,ilen_find));if(find_result.find(find_str.c_str())!= string::npos){//cout<<"\r\n find! \r\n"<<endl;path_new.append(file_pre.c_str());path_new.append(file_exe.c_str());cout<<"Old file"<<path_old.c_str()<<endl;cout<<"New file"<<path_new.c_str()<<endl;//check path_new if exist?int access_rs=0;access_rs = access(path_new.c_str(), 0) ;if(access_rs == 0)//if ((fopen(path_new.c_str(),"r"))!=0){cout<<"Files has existed!"<<path_new.c_str()<<endl;}else{rename(path_old.c_str(),path_new.c_str());}}}else{cout<<"Not find any file!"<<endl;}}  }  _findclose(lf);  //cin.get();return true; 
}void OnBnClickedButton1()
{// TODO: 在此添加控件通知处理程序代码CString sz_Path=_T("");CString sz_Del=_T("");GetDlgItemText(IDC_EDIT1,sz_Path);GetDlgItemText(IDC_EDIT2,sz_Del);string str_path="";str_path.append(sz_Path);cout<<str_path<<endl;string str_del="";str_del.append(sz_Del);change_name(str_path.c_str(),str_del.c_str());MessageBox("Successfully!",_T("title"),MB_OK);
}

在VS2010上面测试没问题
