将多个文件从目录复制到某个位置 [英] copy multiple files from a directory to a location

问题描述

  string  date = DateTime.Today.ToString（ < span class =code-string> yyyyMMdd）; 
  string  dirPath = @ \\ path; 
  string  backup = @ \\ path; 
  string  backupfile = Path.Combine（备份，日期）; 
  string  filepattern1 =   LS _ * .txt ; 
  string  filepattern2 =   PS _ * .txt ; 
  string  filepattern3 =   MS _ * .txt ; 

  string  [] filesHD =目录。 GetFiles（dirPath，filepattern1）; 
  string  [] filesDT = Directory.GetFiles（dirPath，filepattern2）; 
  string  [] filesTD = Directory.GetFiles（dirPath，filepattern3）; 

这里我想将filesHD Array，filesDT Array和filesTD Array中的所有文件复制到备份文件中。怎么可能？

解决方案

试试这样..

  string  date = DateTime.Today.ToString（  YYYYMMDD）; 
  string  dirPath =  @  D：\\ \\Files\; 
  string  backup =  @  D：\\ \\Files\output\; 
  string  backupfile = Path.Combine（备份，日期）; 
  string  filepattern1 =   LS _ * .txt ; 
  string  filepattern2 =   PS _ * .txt ; 
  string  filepattern3 =   MS _ * .txt ; 
 
  string  [] filesHD = Directory.GetFiles（dirPath，filepattern1）; 
  string  [] filesDT = Directory.GetFiles（dirPath，filepattern2）; 
  string  [] filesTD = Directory.GetFiles（dirPath，filepattern3）; 
 Directory.CreateDirectory（backupfile）; ; 
 filesHD.ToList（）。ForEach（k = >  File.Copy（k，Path.Combine（backupfile，Path.GetFileName（k））） ）; 
 filesDT.ToList（）。ForEach（k = >  File.Copy（k，Path.Combine（backupfile，Path.GetFileName（k））） ）; 
 filesTD.ToList（）。ForEach（k = >  File.Copy（k，Path.Combine（backupfile，Path.GetFileName（k））） ）; 
 
 Console.WriteLine（  done）; 

注意：照顾验证:)



参考：文件 - >复制，删除，移动 [ ^

string date = DateTime.Today.ToString("yyyyMMdd");
            string dirPath = @\\path;
            string backup = @\\path;
            string backupfile = Path.Combine(backup,date);
            string filepattern1 = "LS_*.txt";
            string filepattern2 = "PS_*.txt";
            string filepattern3 = "MS_*.txt";

string[] filesHD = Directory.GetFiles(dirPath, filepattern1);
           string[] filesDT = Directory.GetFiles(dirPath, filepattern2);
           string[] filesTD = Directory.GetFiles(dirPath, filepattern3);

here I want to copy all the files from filesHD Array, filesDT Array and filesTD Array to the backup file. How could it be possible ?

解决方案

Try like this..

string date = DateTime.Today.ToString("yyyyMMdd");
            string dirPath = @"D:\Files\";
            string backup = @"D:\Files\output\";
           string backupfile = Path.Combine(backup,date);
           string filepattern1 = "LS_*.txt";
           string filepattern2 = "PS_*.txt";
           string filepattern3 = "MS_*.txt";

           string[] filesHD = Directory.GetFiles(dirPath, filepattern1);
           string[] filesDT = Directory.GetFiles(dirPath, filepattern2);
           string[] filesTD = Directory.GetFiles(dirPath, filepattern3);
           Directory.CreateDirectory(backupfile); ;
           filesHD.ToList().ForEach(k => File.Copy(k, Path.Combine(backupfile, Path.GetFileName(k))));
           filesDT.ToList().ForEach(k => File.Copy(k, Path.Combine(backupfile, Path.GetFileName(k))));
           filesTD.ToList().ForEach(k => File.Copy(k, Path.Combine(backupfile, Path.GetFileName(k))));

           Console.WriteLine("done");

note: Take care of validations :)
