为什么要使用String.Format?[重复]

字符串输出:C#中的格式还是concat? (31个答案)
7年前关闭。
为什么有人会用String.FormatC#和VB .NET而不是串联运算符(&在VB和+C#中)?
主要区别是什么?为什么每个人都对使用如此感兴趣String.Format?我很好奇。
回答:
我可以看到许多原因:
string s = string.Format("Hey, {0} it is the {1}st day of {2}.  I feel {3}!", _name, _day, _month, _feeling);vs:
string s = "Hey," + _name + " it is the " + _day + "st day of " + _month + ".  I feel " + feeling + "!";(这包括您可以编写自定义格式符的事实)
string s = string.Format("Invoice number: {0:0000}", _invoiceNum);vs:
string s = "Invoice Number = " + ("0000" + _invoiceNum).Substr(..... /*can't even be bothered to type it*/)如果我要将字符串模板存储在数据库中怎么办?使用字符串格式:
_id         _translation  1         Welcome {0} to {1}.  Today is {2}.
  2         You have {0} products in your basket.
  3         Thank-you for your order.  Your {0} will arrive in {1} working days.
vs:
_id         _translation  1         Welcome
  2         to
  3         .  Today is
  4         . 
  5         You have
  6         products in your basket.
  7         Someone
  8         just shoot
  9         the developer.
