在C#中移动目录及其所有内容(文件或文件夹)的最佳方式是什么?
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
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:,您将得到IOException
试图将目录移动到其他卷。
destDirName已存在。
sourceDirName和destDirName参数引用同一个文件或目录。
因此,请验证以上任何一项是否导致错误。
此外,您可能会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造成的,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.
}
你可以试试这个
DirectoryInfo dir = new DirectoryInfo(source);
dir.MoveTo(newLocation);
使用系统。Io.
string source = @"c:'new";
string dest = @"c:'newnew";
Directory.Move(source, dest);
这里有一个例子。。。您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
}
下面的解决方案如何,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);
}
