如何替换文件名 [英] How to Replace File Name

问题描述

朋友，

我已替换了文件名..

Hi Friends ,

I have replace the file name..

string pfname = @"E:\Image\" + filename + ".jpg";
           string BackUp=@"E:\BackupImage\" + filename + "1.jpg";
           MemoryStream ms = new MemoryStream(image);
           Image returnImage = Image.FromStream(ms);
           FileInfo ffi = new FileInfo(pfname);
           if (ffi.Exists)
           {
               //System.IO.FileInfo file = new System.IO.FileInfo(pfname);
               //System.IO.FileInfo f = file.CopyTo(pfname, true);
               //file.Delete();
              ReplaceFile(pfname, pfname, BackUp);
              // System.IO.File.Delete(pfname);
               //System.IO.F
           }
           returnImage.Save(@"E:\Image\" + filename + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

public static void ReplaceFile(string FileToMoveAndDelete, string FileToReplace, string BackupOfFileToReplace)
    {
        File.Replace(FileToMoveAndDelete, FileToReplace, BackupOfFileToReplace, false);

    }

推荐答案

处理内存流，然后调用delete函数.

dispose the memory stream then call delete function.

if (ffi.Exists)
          {
ms.Close();
              //System.IO.FileInfo file = new System.IO.FileInfo(pfname);
              //System.IO.FileInfo f = file.CopyTo(pfname, true);
              //file.Delete();
             ReplaceFile(pfname, pfname, BackUp);
             // System.IO.File.Delete(pfname);
              //System.IO.F
          }
