如何格式化字符串

在我的應用程序中，我確定網絡更改發生時。我有，我用一些示例代碼，但我想結果字符串以一定的方式格式化如何格式化字符串

string change = string.Empty; 
     switch (e.NotificationType) 
     { 
      case NetworkNotificationType.InterfaceConnected: 
       change = "Connected to "; 
       break; 
      case NetworkNotificationType.InterfaceDisconnected: 
       change = "Disconnected from "; 
       break; 
      case NetworkNotificationType.CharacteristicUpdate: 
       change = "Characteristics changed for "; 
       break; 
      default: 
       change = "Unknown change with "; 
       break; 
     } 

     string changeInformation = String.Format(" {0} {1} {2} ({3})", 
        DateTime.Now.ToString(), change, e.NetworkInterface.InterfaceName, 
        e.NetworkInterface.InterfaceType.ToString()); 

     // We are making UI updates, so make sure these happen on the UI thread. 
     Dispatcher.BeginInvoke(() => 
     { 
      Changes.Add(changeInformation); //Changes contains the changeInformation 
     });

目前的結果看起來像

但這不是在格式化好所有，而且往往會有時混亂。我希望能夠對其進行格式化，以使DateTime.Now.ToString()位於最上面，然後是change位於下一行，然後是e.NetworkInterface.InterfaceName和e.NetworkInterface.InterfaceType.ToString()。我怎麼能這樣做？

使用換行符...（ \ n幫助） – Vogel612

'String.Format（「{0} \ n {1} \ n {2}（{3}）」，...' –

使用明確\r\n或更好，Environment.NewLine，例如，

String.Format(" {0}{1}{2}{3}{4}({5})", 
       DateTime.Now, Environment.NewLine, 
       change, Environment.NewLine, 
       e.NetworkInterface.InterfaceName, 
       e.NetworkInterface.InterfaceType);

還要注意的是，你不需要在參數赤裸裸.ToString() - 這是在String.Format()

暗示我認爲你必須添加新行

string changeInformation = String.Format(" {0} {1} {2} {3} ({4})", 
        DateTime.Now.ToString(), Environment.NewLine, change, e.NetworkInterface.InterfaceName, 
        e.NetworkInterface.InterfaceType.ToString());
