C# 将整个可移动磁盘复制到共享文件夹

Question

在我的应用程序中，我需要将整个 XDCam 磁盘（教授广播记录磁盘）复制到我们的文件服务器。但是以下功能似乎只有在源驱动器不是根目录时才会起作用。

不工作

    FileSystem.CopyDirectory("E:\", serverPath + this.targtetDirectory + "\", UIOption.AllDialogs);

工作

FileSystem.CopyDirectory("E:\Clip\", serverPath + this.targtetDirectory + "\", UIOption.AllDialogs);

如何将整个磁盘复制到我的目标目录？

Answer 1

我以前是这样的：

void CopyAppFiles(string SourcePath, string )
{
    foreach (string dirPath in Directory.GetDirectories(SourcePath, "*", SearchOption.AllDirectories))
    {
        Directory.CreateDirectory(dirPath.Replace(SourcePath, DestinationPath));
    }

    foreach (string newPath in Directory.GetFiles(SourcePath, "*.*", SearchOption.AllDirectories))
    {
        File.Copy(newPath, newPath.Replace(SourcePath, DestinationPath), true);
    }
}

随着进步，你可以做类似的事情

void CopyAppFiles(string SourcePath, string )
{
    string[] dirs = Directory.GetDirectories(SourcePath, "*", SearchOption.AllDirectories);
    string[] files = Directory.GetFiles(SourcePath, "*.*", SearchOption.AllDirectories)

    int totalOperations = dirs.length + files.length;

    for(int i = 0; i < dirs.length; i++)
    {
        Directory.CreateDirectory(dirs[i].Replace(SourcePath, DestinationPath));

        ReportProgress(i, totalOperations);
    }

    for(int i = 0; i < files.length; i++)
    {
        File.Copy(files[i], files[i].Replace(SourcePath, DestinationPath), true);

        ReportProgress(i + dirs.length, totalOperations);
    }
}

void ReportProgress(int currentOperation, int totalOperations)
{
    //TODO
}

最适合小文件

不要以根目录为目标，而是尝试获取根目录的所有子目录并单独复制它们：

string destinationDir = serverPath + this.targetDirectory + @"\";
foreach (var file in Directory.GetFiles(@"E:\", "*.*", System.IO.SearchOption.AllDirectories))
{
    File.Copy(file, destinationDir + file.Substring(targetDirectory.Length));
}
