C#中的命名字符串格式 [英] Named string formatting in C#

问题描述

有没有办法在 C# 中按名称而不是位置来格式化字符串?

在 python 中，我可以做类似这个例子的事情(无耻地从 here):

<预><代码>>>>打印 '%(language)s 有 %(#)03d 个引号类型.'% {'语言':Python"，#":2}Python 有 002 种引用类型.

在 C# 中有没有办法做到这一点?比如说:

String.Format("{some_variable}: {some_other_variable}", ...);

能够使用变量名来做到这一点会很好，但字典也是可以接受的.

解决方案

没有处理这个的内置方法.

这是一种方法

string myString = "{foo} is {bar} and {yadi} is {yada}".Inject(o);

这是另一个

Status.Text = "{UserName} 最后登录时间为 {LastLoginDate}".FormatWith(user);

部分基于上述两种方法的第三种改进方法，来自 Phil Haack

Is there any way to format a string by name rather than position in C#?

In python, I can do something like this example (shamelessly stolen from here):

>>> print '%(language)s has %(#)03d quote types.' % 
      {'language': "Python", "#": 2}
Python has 002 quote types.

Is there any way to do this in C#? Say for instance:

String.Format("{some_variable}: {some_other_variable}", ...);

Being able to do this using a variable name would be nice, but a dictionary is acceptable too.

解决方案

There is no built-in method for handling this.

Here's one method

string myString = "{foo} is {bar} and {yadi} is {yada}".Inject(o);

Here's another

Status.Text = "{UserName} last logged in at {LastLoginDate}".FormatWith(user);

A third improved method partially based on the two above, from Phil Haack
