[英]The best way to move a directory with all its contents(files or folders) in C#?
在 C# 中移動目錄及其所有內容(文件或文件夾)的最佳方法是什么?
我使用了以下代碼,但它拋出了The Directory is not empty
異常:
Microsoft.VisualBasic.FileIO.FileSystem.MoveDirectory(sourceFullName, destFullName, true);
Directory.Move(sourceFullName, destFullName); //Added in edit
MSDN示例就足夠了。
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 所說,如果出現以下情況,您將收到 IOException:
試圖將目錄移動到不同的卷。
destDirName 已經存在。
sourceDirName 和 destDirName 參數引用相同的文件或目錄。
因此,請驗證上述任何一項是否導致錯誤。
此外,您可以考慮在移動之前刪除現有目錄。 如果錯誤是由於上面提到的第二個選項引起的,這將避免引發錯誤。
if(Directory.Exists(destinationDirectory) == false)
{
Directory.Move(sourceDirectory, destinationDirectory);
}
else
{
//Delete existing directory
//But make sure you really want to delete.
}
你可以試試這個
DirectoryInfo dir = new DirectoryInfo(source);
dir.MoveTo(newLocation);
使用 System.Io。
string source = @"c:\new";
string dest = @"c:\newnew";
Directory.Move(source, dest);
這是一個例子......你應該在移動目錄之前移動所有文件
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!");
}
使用它可以幫助您:
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
}
下面的解決方案怎么樣,它運行良好:
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);
}
