如何在目录中创建子目录

Question

In other words, i have temp folder where i store my extracted files. How do i create a folder in that temp folder so that all files are extracted or unzipped in this folder, which is inside the temp folder?

Answer 1

Simple

Directory.CreateDirectory(Path.Combine("<Your temp folder>", "<DirectoryName>"));

Make sure you have the proper rights given to the aspnet worker process to create the folder.

Answer 2

string tempFolderAbsolutePath = @"C:\Temp";
string subFolderRelativePath = @"SubTemp1";

DirectoryInfo tempFolder = new DirectoryInfo( tempFolderAbsolutePath );
DirectoryInfo subFolder = tempFolder.CreateSubdirectory( subFolderRelativePath );

string tempFileName = String.Concat( Guid.NewGuid().ToString(), @".tmp" );
string textData = @"Temp text data";

using (StreamWriter streamWriter = File.CreateText( Path.Combine( subFolder.FullName, tempFileName ) ))
{
        streamWriter.Write( textData );
        streamWriter.Flush();
        streamWriter.Close();
}

Answer 6

System.IO.Directory.CreateDirectory()在指定路径中创建所有目录和子目录，除非它们已经存在。

string address = Directory.CreateDirectory(newDirectory).CreateSubdirectory("SubDir").FullName;
