如何在創建子目錄中應用日期格式

Question

我希望日期格式爲文件夾名稱（27-07-2010）..如何命名它？我希望把它作爲我的子目錄

Answer 1

您可以System.IO.Directory.CreateDirectory創建目錄，你可以用一個日期格式指定名稱字符串：

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

Answer 2

試試這個：

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")));
