在c#中将文件夹从一个驱动器移动到另一个驱动器[关闭]

Question

Here is my source file and destination file";

Source :  E:\\Test\Test_Content\\ABC12
Destination: F:\\Test\GetContent

我想将文件夹 ABC12 从 E 盘移动到 GetContent 文件夹中的目标路径，但是 ABC12 包含不同的子文件夹。 ABC12 文件夹应与子文件夹一起完全移动到目标文件夹。请帮助我。

我收到以下错误：我收到这样的错误“源路径和目标路径必须具有相同的根。移动无法跨卷工作。”

 string sfolder="Path of the folder to move which is in project directory in E drive";
 string path = "~/UContent" + "/" + sfolder;
                string extractfiles = Server.MapPath("UContent"+"/");
               System.IO.Directory.Move(extractfiles+"/"+sfolder,@"F:/GetContent/");

Answer 1

你需要这个：

static public void CopyFolder(string sourceFolder, string destFolder )
{
    Directory.CreateDirectory( destFolder );
    string[] files = Directory.GetFiles( sourceFolder );
    foreach (string file in files)
    {
        string name = Path.GetFileName( file );
        string dest = Path.Combine( destFolder, name );
        File.Copy( file, dest );
    }
    string[] folders = Directory.GetDirectories( sourceFolder );
    foreach (string folder in folders)
    {
       string name = Path.GetFileName( folder );
       string dest = Path.Combine( destFolder, name );
        CopyFolder( folder, dest );
    }
}

Answer 2

移动功能仅在源和目的地位于同一驱动器中时才有效

在这种情况下，您可以先使用“复制”，然后再使用“删除”

请参阅以下链接将目录复制到另一个驱动器

将目录复制到不同的驱动器

然后使用

Directory.Delete(source_path);

Answer 3

你必须使用文件复制

public class CopyFiles {

internal event EventHandler Successful;

internal event EventHandler Failed;

private string Reason;

private string mstrSource;

private string mstrDestination;

internal void StartCopying() {
    try {
        CopyDirectory(mstrSource, mstrDestination);
        Successful();
    }
    catch (Exception ex) {
        Failed(ex.Message);
    }
}

private bool CopyDirectory(string Src, string Dest) {
    // add Directory Seperator Character (\) for the string concatenation shown later
    if ((Dest.Substring((Dest.Length - 1), 1) != Path.DirectorySeparatorChar)) {
        Dest = (Dest + Path.DirectorySeparatorChar);
    }
    // If Directory.Exists(Dest) = False Then Directory.CreateDirectory(Dest)
    string[] Files = Directory.GetFileSystemEntries(Src);
    foreach (string element in Files) {
        if ((Directory.Exists(element) == true)) {
            // if the current FileSystemEntry is a directory,
            // call this function recursively
            Directory.CreateDirectory((Dest + Path.GetFileName(element)));
            CopyDirectory(element, (Dest + Path.GetFileName(element)));
        }
        else {
            // the current FileSystemEntry is a file so just copy it
            File.Copy(element, (Dest + Path.GetFileName(element)), true);
        }
    }
}

internal string Source {
    get {
        return mstrSource;
    }
    set {
        mstrSource = value;
    }
}

internal string Destination {
    get {
        return mstrDestination;
    }
    set {
        mstrDestination = value;
    }
}

}

Answer 4

您必须手动执行此操作，因为正如您在评论中提到的，您无法将其复制到两个不同的卷中。这是有据可查的事实。

Stream fs = File.OpenRead(@"C:\tools\a.csv");
Stream target = File.OpenWrite(@"D:\mystuff\a.csv");
fs.CopyTo(target);
target.Close();
fs.Close();

注意：自 .NET 4.0 起，

CopyTo()

被添加到

Stream

类型

完成后，您可以删除原始文件。

File.Delete(@"C:\tools\a.csv");

Answer 5

使用中有什么问题？

Directory.Move(sourceDirectory, destinationDirectory);

或者

DirectoryInfo di = new DirectoryInfo("TempDir");

if (di.Exists == false)
    di.Create();

DirectoryInfo dis = di.CreateSubdirectory("SubDir");


if (Directory.Exists("NewTempDir") == false)
    di.MoveTo("NewTempDir");
