C# 无法复制c中的文件夹#

问题在于，将netscan.zip文件中的文件复制到usb时。 它将所有文件解压缩到root

以下是KHTEM文件夹中文件的外观：

c:\Data\install\     <-  Files
c:\Data\info         <-  Files
c:\Knowhow.exe

我不知道我做错了什么

您需要确定循环中的当前项是文件还是目录。

如果它是一个文件，那么写一个复制代码，如果它是一个目录，那么使用

System.IO.directory.CreateDirectory（“”）手动创建它
您还需要复制每个文件夹-类似这样的方法可以工作：

public static void CopyFolder(string sourcePath, string destinationPath)
{
     Directory.CreateDirectory(destinationPath);
     // Copy files first.
     foreach(var sourceFile in Directory.GetFiles(sourcePath))
     {
          string destFile = Path.Combine(destinationPath, Path.GetFileName(sourceFile));
          File.Copy(sourceFile, destFile, true);
     }
     foreach(var sourceSubPath in Directory.GetDirectories(sourcePath))
     {
          string destPath = Path.Combine(destinationPath, Path.GetFileName(sourceSubPath));
          CopyFolder(sourceSubPath, destPath);
     }
}

您应该调用CopyFolder（tempFolder，root）

请注意，未对其进行测试，您需要调试CopyFolder方法以验证文件夹名称中是否有
？您是否收到任何抛出的异常或警告？不，此代码从头到尾都有效。但是我不会复制c:\khtemp中的子文件夹。这些子文件夹的名称@Tobbe中是否有
？在移动文件夹时有类似的问题，因为System.IO.File似乎有问题，并将这些文件夹视为文件…在这个例子中，当使用这个文件夹时，我称之为“数据”和“信息”的文件夹将把文件夹和子文件夹复制到usb的根目录下。所以我会得到一个F:\info，但它看起来像是C:\KHtemp\data\info。
public static void CopyFolder(string sourcePath, string destinationPath)
{
     Directory.CreateDirectory(destinationPath);
     // Copy files first.
     foreach(var sourceFile in Directory.GetFiles(sourcePath))
     {
          string destFile = Path.Combine(destinationPath, Path.GetFileName(sourceFile));
          File.Copy(sourceFile, destFile, true);
     }
     foreach(var sourceSubPath in Directory.GetDirectories(sourcePath))
     {
          string destPath = Path.Combine(destinationPath, Path.GetFileName(sourceSubPath));
          CopyFolder(sourceSubPath, destPath);
     }
}
