我怎样才能在formatString中使用百分比％没有它乘以100？ [英] How can I use a percent % in FormatString without it multiplying by 100?

问题描述

我想格式化整数百分比没有它乘以100，如图这里。因为我的源是一个int，首先除以100是不是有效选项。 ？这是可能的。

  [DisplayFormat（DataFormatString ={0：＃％}）] 
  

解决方案

您可以逃脱％人物：

  [DisplayFormat（DataFormatString = @{0：＃\％}）] 
  

---

请注意，有使用两种方法 \ 作为转义字符：如果一个前缀字符串和逐字符号（ @ ），那么 \ 字符包含在字符串中原来的样子，这意味着作为格式字符串的一部分的单 \ 将起作用作为转义字符。

没有 @ 逐字符号， \ s的解释为逃逸字符串的由编译器的，因此需要加以本身转义，如 \\ 。

选择一个或另一个，但不能同时：

  @{ 0：＃\％} - >右
{0：＃\\％} - >右
 @{0：＃\\％} - >错误的
  

I would like to format an integer as a percent without it multiplying by 100 as shown here. Because my source is an int, dividing it first by 100 is not a valid option. Is this possible?

[DisplayFormat(DataFormatString = "{0:#%}")]

解决方案

You can escape the % character:

[DisplayFormat(DataFormatString = @"{0:#\%}")]

---

Note that there are two ways to use \ as an escape character: if you prefix a string literal with the verbatim symbol (@), then \ characters are included in the string as-is, which means that as part of a format string a single \ will function as an escape character.

Without the @ verbatim symbol, \s are interpreted as escape strings by the compiler and as such need to be escaped themselves, as \\.

Pick one or the other, but not both:

@"{0:#\%}"  -> right
"{0:#\\%}"  -> right
@"{0:#\\%}" -> wrong
