How to create multiple directories from a single full path in C#?
提问by Joan Venge
If you have a full path like: "C:\dir0\dir1\dir2\dir3\dir4\"how would you best implement it so that all directories are present?
如果您有一个完整的路径，例如："C:\dir0\dir1\dir2\dir3\dir4\"您将如何最好地实现它以便所有目录都存在？
Is there a method for this in the BCL? If not, what's the most elegant way to do this?
BCL中是否有这种方法？如果不是，那么最优雅的方法是什么？

I would call Directory.CreateDirectory(@"C:\dir0\dir1\dir2\dir3\dir4\").
我会打电话给Directory.CreateDirectory(@"C:\dir0\dir1\dir2\dir3\dir4\")。
Contrary to popular belief, Directory.CreateDirectorywill automatically create whichever parent directories do not exist.
In MSDN's words, Creates all directories and subdirectories as specified by path.
与流行的看法相反，Directory.CreateDirectory将自动创建不存在的父目录。
用 MSDN 的话来说，Creates all directories and subdirectories as specified by path.
If the entire path already exists, it will do nothing. (It won't throw an exception)
如果整个路径已经存在，它将什么都不做。（它不会抛出异常）

Create directories from complete filepath
从完整的文件路径创建目录
private String EvaluatePath(String path){
try
{
String folder = Path.GetDirectoryName(path);
if (!Directory.Exists(folder))
{
// Try to create the directory.
DirectoryInfo di = Directory.CreateDirectory(folder);
}
}
catch (IOException ioex)
{
Console.WriteLine(ioex.Message);
return "";
}
return path;
}
