你如何编写反斜杠的代码？



我想要像回车一样的代码：



a = b + vbcrlf + c;



除了BackSlash。



我遇到了麻烦使用此代码：

  var  localpathandfile = TextBox2.Text +   \+ System.IO.Path.GetFileName（FileUpload1.FileName）.ToString（）;  

我收到错误\



当我离开\ out时没有错误。

解决方案

只需使用两个反斜杠：\\

第一个用作转义字符允许字符串常量中的控制字符。

由于反斜杠被视为转义字符，因此必须使用两个反斜杠才能得到一个反斜杠（\\）。

<块引用>试试2反斜杠（\\）



它将反斜杠编码为反斜杠。单个反斜杠启动代码，例如\ n for newline

How do you write the code for a Backslash?

I want the code like carriage return:

a = b + vbcrlf + c;

except with BackSlash.

I am having trouble with this code:

var localpathandfile = TextBox2.Text + "\" + System.IO.Path.GetFileName(FileUpload1.FileName).ToString();

I get the error at \

When I leave \ out there is no error.

解决方案

Just use two backslashes thus: "\\"
The first one is used as the escape character to allow control characters in string constants.

Since backslash is treated as an escape character you must use two backslashes to get a single one ("\\").

try 2 Backslash ( "\\" )

it's coding the Backslash to be a backslash. a single backslash starts a code like \n for newline
