是否可以使用 StreamWriter 创建目录？
回答by Chris Hynes
No. You can't actually create a directory using a StreamWriter. Use Directory.CreateDirectoryinstead.
不可以。您实际上无法使用 StreamWriter 创建目录。请改用Directory.CreateDirectory。
If you're trying to read the directory name out of a file stream and then create a file based on that text, you'll need something like this:
如果您尝试从文件流中读取目录名称，然后根据该文本创建一个文件，您将需要如下内容：
FileStream fs; // this is the filestream from somewhere. make sure to dispose it
using (StreamReader r = new StreamReader(fs))
Directory.CreateDirectory(r.ReadToEnd());
