复制一个文件夹的内容，代码参考

``` cs
    public static void CopyDirectory(string sourceDir, string targetDir)
    {
        DirectoryInfo dir = new DirectoryInfo(sourceDir);
        DirectoryInfo[] dirs = dir.GetDirectories();
 
        // If the source directory does not exist, throw an exception.
        if (!dir.Exists)
        {
            throw new DirectoryNotFoundException($"Source directory does not exist or could not be found: {sourceDir}");
        }
 
        // If the destination directory does not exist, create it.
        if (!Directory.Exists(targetDir))
        {
            Directory.CreateDirectory(targetDir);
        }
 
        // Get the files in the directory and copy them to the new location.
        FileInfo[] files = dir.GetFiles();
        foreach (FileInfo file in files)
        {
            string tempPath = Path.Combine(targetDir, file.Name);
            file.CopyTo(tempPath, false);
        }
 
        // If copying subdirectories, copy them and their contents to the new location.
        foreach (DirectoryInfo subdir in dirs)
        {
            string tempPath = Path.Combine(targetDir, subdir.Name);
            CopyDirectory(subdir.FullName, tempPath);
        }
    }
```

如果是需要整个文件夹替换，执行上述操作之前，可以先判空，然后删除文件夹

``` cs
        if (Directory.Exists(RemoteHotUpdateRootPath))
        {
            Directory.Delete(RemoteHotUpdateRootPath, true);
        }
```

完整调用，就是删除文件夹，然后再复制文件夹过去即可
