字符串变量奇怪的行为 [英] String variable strange behavior

问题描述

我在变量中有一些字符串str_tmp =" C：\ TMP \"

我想在文本框中显示它（@ -quoted），所以我正在使用tbx .Text =

@str_tmp;但由于一些奇怪的原因，这不起作用。它处理

转义序列。有什么问题???

I have some string in variable str_tmp = "C:\TMP\"
I want to display it in textbox (@-quoted), so I''m using tbx.Text =
@str_tmp; but for some strange reason this does not work. it processes
escape sequence. What is the problem???

推荐答案

您使用了错误的转义字符，在声明您的

var时使用它：

string srt_tmp = @" c：\ tmp" ;;

分配时不必使用它：

tbx.Text = @str_tmp;

你刚才这样做

tbx.Text = str_tmp;

干杯，

Hi,

You are using incorrectly the escape char, use it when you declare your
var:
string srt_tmp = @"c:\tmp";
you don''t have to use it when you assign it:
tbx.Text = @str_tmp;
you just do
tbx.Text = str_tmp;
Cheers,

Do没有帮助。

我有一个类似的结构：


public struct SomeStringStruct

{

public string A_String;

public SomeStringStruct（string a_string）

{

A_String = a_string;

}

}

现在我应该在哪里添加@以便能够接收@ -quoted字符串，例如。

SomeStringStruct a = new SomeStringStruct（" \\ \\ n \\ n \\ n \\ n \\ n\\ n）

Console.WriteLine（a.A_String）; //应该返回\ n \ n \ n而不是< CR>< CR>< CR>

您想要dot.NET吗？只需询问：

"请， www.dotnet.us

：eu ************* @ TK2MSFTNGP11.phx.gbl ...

Do not helps.
I have a struct like:

public struct SomeStringStruct
{
public string A_String;
public SomeStringStruct(string a_string)
{
A_String = a_string;
}
}
Now where should I add @ in order to be able to recieve @-quoted strings eg.
SomeStringStruct a = new SomeStringStruct ("\n\n\n")
Console.WriteLine(a.A_String); // Should return \n\n\n and not <CR><CR><CR>

你错误地使用了转义字符，当你声明你的字符串时使用它
var：
字符串srt_tmp = @" c：\ tmp" ;;
你不要必须在分配时使用它：
tbx.Text = @str_tmp;
你刚才做的
tbx.Text = str_tmp;

干杯，

@只是对于源代码中的文字硬编码字符串非常有用。


如果要将不可打印的字符转换为文本

表示其转义序列（例如< CR>到''\ n''），你将需要自己进行替换，例如


string s2 = s1。替换（\ n，@" \ n"）; // ...依此类推


P.

@ is only useful for literal hard-coded strings in your source code.

If you want to convert non-printable characters to the text
representation of their escape sequences (e.g. <CR> to ''\n''), you will
have to do the replacements yourself, e.g.

string s2 = s1.Replace("\n", @"\n"); // ... and so on
