C#获取指定目录下某种格式文件集并备份到指定文件夹

1.获取文件的路径和移动到文件夹信息

string fileName = "";
          string sourceFile = @"F:\Test文件夹\CSV";
          string bakFilePath = @"F:\Test文件夹\CSV\bak";

2.获取文件夹下文件信息，并移动到Bak操作。

//匹配.csv的文件路径地址集合
          string[] FullfillfilesList = Directory.GetFiles(sourceFile, "*.csv", 0);
          if (FullfillfilesList.Length > 0)
          {
              foreach (string Fullfillfiles in FullfillfilesList)
              {
                  //每一个文件名称
                  fileName = Fullfillfiles.Substring(Fullfillfiles.LastIndexOf('\\') + 1);
                  //移动到Bak文件夹
                  ExecutionResult res = MoveFileToBak(sourceFile + "/" + fileName, bakFilePath, fileName);
              }
          }

3.文件移动到Bak方法

public static ExecutionResult MoveFileToBak(string sourceFile, string bakFilePath, string bakFileName)
      {
          ExecutionResult result;
          FileInfo tempFileInfo;
          FileInfo tempBakFileInfo;
          DirectoryInfo tempDirectoryInfo;

          result = new ExecutionResult();
          tempFileInfo = new FileInfo(sourceFile);
          tempDirectoryInfo = new DirectoryInfo(bakFilePath);
          tempBakFileInfo = new FileInfo(bakFilePath + "\\" + bakFileName);
          try
          {
              if (!tempDirectoryInfo.Exists)
                  tempDirectoryInfo.Create();
              if (tempBakFileInfo.Exists)
                  tempBakFileInfo.Delete();
              //move file to bak
              tempFileInfo.MoveTo(bakFilePath + "\\" + bakFileName);

              result.Status = true;
              result.Message = "Move File To Bak OK";
              result.Anything = "SEND OK";
          }
          catch (Exception ex)
          {
              result.Status = false;
              result.Anything = "SEND Fail";
              result.Message = ex.Message;      
          }

          return result;
      }
