如何在C＃中使用字符串中的特殊字符？ [英] How to use special characters in strings like in C#?

问题描述

是否可以在VB.NET

字符串中使用特殊字符，如\ n或\t，就像在C＃？我的猜测是否定的，但也许我有什么东西我不知道。


如果不可能，有人知道吗一个VB.NET函数（有人

必须已经编码）这将解释包含

这些特殊字符的字符串，并处理它们与在C＃中处理它们一样？ />

谢谢！

不，这是不受支持的。这是一个罕见的情况，你真的需要一个字符串文字中的\\\


。相反，使用''ControlChars.NewLine''将

包含特定于平台的新行字符串。 ''ControlChars''提供其他

字符，如''Cr''，''Lf''和''Tab''。


\\ \\\\

Dim s As String = _

" Hello" &安培; ControlChars.NewLine& _

" World"

///

必须已经编码了这个，它会解释包含这些特殊字符的字符串，并在C＃中处理它们吗？

支持C＃字符串文字中的转义字符是一个编译器

功能，这意味着它只能在编译时工作。编译器

将用转义字符替换转义序列。 C＃没有

提供了一种在运行时执行unescaping的方法。

我倾向于做的是：


Dim nl As String = ControlChars.NewLine等。至少它会缩短

你的代码很多

Mhm ...我更喜欢常数：


\\\

Const NL As String = ControlChars.NewLine

///

Hi,

Is it possible to use special characters like \n or \t in a VB.NET
string, just like in C#? My guess is NO, but maybe there''s something I
don''t know.

If it''s not possible, does anybody know of a VB.NET function (somebody
must have coded this already) that will interpret strings containings
those special characters, and handle them the same as in C#?

Thanks!

No, that''s not supported. It''s a rare case that you really need a "\n"
inside a string literal. Instead, use ''ControlChars.NewLine'' which will
contain a platform-specific new-line string. ''ControlChars'' provides other
characters like ''Cr'', ''Lf'', and ''Tab'' too.

\\\
Dim s As String = _
"Hello" & ControlChars.NewLine & _
"World"
///

The support for escaped characters in C# string literals is a compiler
feature, which means that it will only work at compile time. The compiler
will replace the escape sequence with the escaped character. C# doesn''t
provide a way to perform the unescaping at runtime.

What I tend to do is say:

Dim nl As String = ControlChars.NewLine etc. At least then it will shorten
your code quite a lot

Mhm... I prefer a constant:

Const NL As String = ControlChars.NewLine
