TESTSTRING\\\
 
  

我怎么能轻易删除呢？

 海峡= str.Substring（2，STR 。长度-4）
  

当然，你必须测试该字符串包含超过4个字符在此之前。另外，在你的情况似乎\\\
是一个换行符。如果你想要做的是去除前导和尾部空格，你应该使用

  str.Trim（）

Is there an easy way to remove the first 2 and last 2 chars in a string?

I have this string:

\nTESTSTRING\n

How could I easily delete them?

解决方案

str = str.Substring(2,str.Length-4)

Of course you must test that the string contains more than 4 chars before doing this. Also in your case it seems that \n is a single newline character. If all you want to do is remove leading and trailing whitespaces, you should use

str.Trim()
