在 C# 中移动目录及其所有内容（文件或文件夹）的最佳方法？

Question

在 C# 中移动目录及其所有内容（文件或文件夹）的最佳方法是什么？

我使用了以下代码，但它抛出了The Directory is not empty异常：

Microsoft.VisualBasic.FileIO.FileSystem.MoveDirectory(sourceFullName, destFullName, true);
Directory.Move(sourceFullName, destFullName); //Added in edit

Answer 1

MSDN示例就足够了。

        string sourceDirectory = @"C:\source";
        string destinationDirectory = @"C:\destination";

        try
        {
            Directory.Move(sourceDirectory, destinationDirectory);  
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }

甚至，正如 MSDN 所说，如果出现以下情况，您将收到 IOException：

• 试图将目录移动到不同的卷。

• destDirName 已经存在。

• sourceDirName 和 destDirName 参数引用相同的文件或目录。

因此，请验证上述任何一项是否导致错误。

此外，您可以考虑在移动之前删除现有目录。 如果错误是由于上面提到的第二个选项引起的，这将避免引发错误。

    if(Directory.Exists(destinationDirectory) == false)
    {
         Directory.Move(sourceDirectory, destinationDirectory);
    }
    else
    {
         //Delete existing directory
         //But make sure you really want to delete.
    }

Answer 2

你可以试试这个

    DirectoryInfo dir = new DirectoryInfo(source);
    dir.MoveTo(newLocation);

Answer 3

使用 System.Io。

string source = @"c:\new";
string dest = @"c:\newnew";
Directory.Move(source, dest);

Answer 4

这是一个例子......你应该在移动目录之前移动所有文件

 string fileName = "test.txt";
        string sourcePath = @"C:\Users\Public\TestFolder";
        string targetPath =  @"C:\Users\Public\TestFolder\SubDir";

        // Use Path class to manipulate file and directory paths. 
        string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
        string destFile = System.IO.Path.Combine(targetPath, fileName);

        // To copy a folder's contents to a new location: 
        // Create a new target folder, if necessary. 
        if (!System.IO.Directory.Exists(targetPath))
        {
            System.IO.Directory.CreateDirectory(targetPath);
        }

        // To copy a file to another location and  
        // overwrite the destination file if it already exists.
        System.IO.File.Copy(sourceFile, destFile, true);

        // To copy all the files in one directory to another directory. 
        // Get the files in the source folder. (To recursively iterate through 
        // all subfolders under the current directory, see 
        // "How to: Iterate Through a Directory Tree.")
        // Note: Check for target path was performed previously 
        //       in this code example. 
        if (System.IO.Directory.Exists(sourcePath))
        {
            string[] files = System.IO.Directory.GetFiles(sourcePath);

            // Copy the files and overwrite destination files if they already exist. 
            foreach (string s in files)
            {
                // Use static Path methods to extract only the file name from the path.
                fileName = System.IO.Path.GetFileName(s);
                destFile = System.IO.Path.Combine(targetPath, fileName);
                System.IO.File.Copy(s, destFile, true);
            }
        }
        else
        {
            Console.WriteLine("Source path does not exist!");
        }

使用它可以帮助您：

        string sourceDir = @"c:\test";
        string destinationDir = @"c:\test1";

        try
        {
            // Ensure the source directory exists
            if (Directory.Exists(sourceDir) == true )
            {
                // Ensure the destination directory doesn't already exist
                if (Directory.Exists(destinationDir) == false)
                {
                    // Perform the move
                    Directory.Move(sourceDir, destinationDir);
                }
                else
                {
                    // Could provide the user the option to delete the existing directory
                    // before moving the source directory
                }
            }
            else
            {
                // Do something about the source directory not existing
            }
        }
        catch (Exception)
        {
            // TODO: Handle the exception that has been thrown
        }

下面的解决方案怎么样，它运行良好：

public static void DeleteDirectory(string targetDir)
{
    string[] files = Directory.GetFiles(targetDir, "*", SearchOption.AllDirectories);
    foreach (string file in files)
        File.Delete(file);
    new Microsoft.VisualBasic.Devices.Computer().FileSystem.DeleteDirectory(targetDir, DeleteDirectoryOption.DeleteAllContents);
}

public static void MoveDirectory(string source, string dest)
{
    new Microsoft.VisualBasic.Devices.Computer().FileSystem.CopyDirectory(source, dest, true);
    DeleteDirectory(source);
}
