我想用c#将一个目录的全部内容从一个位置复制到另一个位置。
使用System似乎没有办法做到这一点。没有大量递归的IO类。
如果我们添加对Microsoft的引用,VB中有一个方法可以使用。VisualBasic:
new Microsoft.VisualBasic.Devices.Computer().
FileSystem.CopyDirectory( sourceFolder, outputFolder );
这似乎是一个相当丑陋的黑客。有没有更好的办法?

下面的代码是微软建议如何复制目录 由亲爱的@iato分享 但是它只是递归地复制源文件夹的子目录和文件,而不复制源文件夹本身(如右键单击->复制)。
但在这个答案下面有一个棘手的方法:
private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs = true)
{
// Get the subdirectories for the specified directory.
DirectoryInfo dir = new DirectoryInfo(sourceDirName);
if (!dir.Exists)
{
throw new DirectoryNotFoundException(
"Source directory does not exist or could not be found: "
+ sourceDirName);
}
DirectoryInfo[] dirs = dir.GetDirectories();
// If the destination directory doesn't exist, create it.
if (!Directory.Exists(destDirName))
{
Directory.CreateDirectory(destDirName);
}
// Get the files in the directory and copy them to the new location.
FileInfo[] files = dir.GetFiles();
foreach (FileInfo file in files)
{
string temppath = Path.Combine(destDirName, file.Name);
file.CopyTo(temppath, false);
}
// If copying subdirectories, copy them and their contents to new location.
if (copySubDirs)
{
foreach (DirectoryInfo subdir in dirs)
{
string temppath = Path.Combine(destDirName, subdir.Name);
DirectoryCopy(subdir.FullName, temppath, copySubDirs);
}
}
}
如果你想递归复制源文件夹和子文件夹的内容,你可以像这样简单地使用它:
string source = @"J:\source\";
string dest= @"J:\destination\";
DirectoryCopy(source, dest);
但是如果你想复制源目录自己(类似于你右键单击源文件夹,然后单击复制,然后在目标文件夹中单击粘贴),你应该像这样使用:
string source = @"J:\source\";
string dest= @"J:\destination\";
DirectoryCopy(source, Path.Combine(dest, new DirectoryInfo(source).Name));

试试这个:
Process proc = new Process();
proc.StartInfo.UseShellExecute = true;
proc.StartInfo.FileName = Path.Combine(Environment.SystemDirectory, "xcopy.exe");
proc.StartInfo.Arguments = @"C:\source C:\destination /E /I";
proc.Start();
你的xcopy参数可能会有所不同,但你知道的。
使用这个类。
public static class Extensions
{
public static void CopyTo(this DirectoryInfo source, DirectoryInfo target, bool overwiteFiles = true)
{
if (!source.Exists) return;
if (!target.Exists) target.Create();
Parallel.ForEach(source.GetDirectories(), (sourceChildDirectory) =>
CopyTo(sourceChildDirectory, new DirectoryInfo(Path.Combine(target.FullName, sourceChildDirectory.Name))));
foreach (var sourceFile in source.GetFiles())
sourceFile.CopyTo(Path.Combine(target.FullName, sourceFile.Name), overwiteFiles);
}
public static void CopyTo(this DirectoryInfo source, string target, bool overwiteFiles = true)
{
CopyTo(source, new DirectoryInfo(target), overwiteFiles);
}
}
下面的代码复制所有文件从源到目标给定的模式在相同的文件夹结构:
public static void Copy()
{
string sourceDir = @"C:\test\source\";
string destination = @"C:\test\destination\";
string[] textFiles = Directory.GetFiles(sourceDir, "*.txt", SearchOption.AllDirectories);
foreach (string textFile in textFiles)
{
string fileName = textFile.Substring(sourceDir.Length);
string directoryPath = Path.Combine(destination, Path.GetDirectoryName(fileName));
if (!Directory.Exists(directoryPath))
Directory.CreateDirectory(directoryPath);
File.Copy(textFile, Path.Combine(directoryPath, Path.GetFileName(textFile)), true);
}
}
容易得多
private static void CopyFilesRecursively(string sourcePath, string targetPath)
{
//Now Create all of the directories
foreach (string dirPath in Directory.GetDirectories(sourcePath, "*", SearchOption.AllDirectories))
{
Directory.CreateDirectory(dirPath.Replace(sourcePath, targetPath));
}
//Copy all the files & Replaces any files with the same name
foreach (string newPath in Directory.GetFiles(sourcePath, "*.*",SearchOption.AllDirectories))
{
File.Copy(newPath, newPath.Replace(sourcePath, targetPath), true);
}
}
你可以一直使用这个,摘自微软网站。
static void Main()
{
// Copy from the current directory, include subdirectories.
DirectoryCopy(".", @".\temp", true);
}
private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
// Get the subdirectories for the specified directory.
DirectoryInfo dir = new DirectoryInfo(sourceDirName);
if (!dir.Exists)
{
throw new DirectoryNotFoundException(
"Source directory does not exist or could not be found: "
+ sourceDirName);
}
DirectoryInfo[] dirs = dir.GetDirectories();
// If the destination directory doesn't exist, create it.
if (!Directory.Exists(destDirName))
{
Directory.CreateDirectory(destDirName);
}
// Get the files in the directory and copy them to the new location.
FileInfo[] files = dir.GetFiles();
foreach (FileInfo file in files)
{
string temppath = Path.Combine(destDirName, file.Name);
file.CopyTo(temppath, false);
}
// If copying subdirectories, copy them and their contents to new location.
if (copySubDirs)
{
foreach (DirectoryInfo subdir in dirs)
{
string temppath = Path.Combine(destDirName, subdir.Name);
DirectoryCopy(subdir.FullName, temppath, copySubDirs);
}
}
}
