如果已存在于文件夹中，如何重命名文件 [英] How to rename file if exist in the folder already

问题描述

我在计时器中使用此功能

每次打勾它会将文件复制到目标路径但是这会覆盖现有文件所以任何人都可以帮助我



我的尝试：

i am using this function in the timer
every tick it will copy the files to the target path but by this it is overwriting the existing files so can any one help me

What I have tried:

<pre> public static void Copy(string sourceDirectory, string targetDirectory)
    {
        DirectoryInfo diSource = new DirectoryInfo(sourceDirectory);
        DirectoryInfo diTarget = new DirectoryInfo(targetDirectory);

        CopyAll(diSource, diTarget);
    }

    public static void CopyAll(DirectoryInfo source, DirectoryInfo target)
    {
        Directory.CreateDirectory(target.FullName);

        // Copy each file into the new directory.
        foreach (FileInfo fi in source.GetFiles())
        {
            Console.WriteLine(@"Copying {0}\{1}", target.FullName, fi.Name);
            fi.CopyTo(Path.Combine(target.FullName, fi.Name), true);
        }

        // Copy each subdirectory using recursion.
        foreach (DirectoryInfo diSourceSubDir in source.GetDirectories())
        {
            DirectoryInfo nextTargetSubDir =
                target.CreateSubdirectory(diSourceSubDir.Name);
            CopyAll(diSourceSubDir, nextTargetSubDir);
        }
    }

    public static void Main()
    {
        string sourceDirectory = @"F:\\payload_Data\\File_Splitted_1";
        string targetDirectory = @"c:\targetDirectory";

        Copy(sourceDirectory, targetDirectory);
    }

    // Output will vary based on the contents of the source directory.
}

推荐答案

这并不复杂：

It's not complex:

if (File.Exists(originalPath))
    {
    File.Move(originalPath, newPath);
    }
