如何在创建子目录中应用日期格式

Question

我希望日期格式为文件夹名称（27-07-2010）..如何命名它？我希望把它作为我的子目录

Answer 1

您可以System.IO.Directory.CreateDirectory创建目录，你可以用一个日期格式指定名称字符串：

var dirName = string.Format("{0:dd-MM-yyyy}", DateTime.Now); 
System.IO.Directory.CreateDirectory(dirName); 

Answer 2

试试这个：

DateTime dateTime;  
dateTime.ToString("dd-MM-yyyy"); 

更新

// The date you want for your folder. 
// Could be: DateTime.Now 
DateTime dateTime; 

// The parent folder you want to create a subfolder in 
// Could be: AppDomain.CurrentDomain.BaseDirectory for current dir 
string parentFolder; 

Directory.CreateDirectory(Path.Combine(parentFolder, dateTime.ToString("dd-MM-yyyy")));
