[英]C# what is the regex expression for Special characters
What is the regex expression for the special characters that is greater than 128 in the ASCII extended table? ASCII扩展表中大于128的特殊字符的正则表达式是什么?
I have a line with special characters like below, and every special char should be replaced with a space. 我在一行中包含特殊字符,如下所示,每个特殊字符都应替换为一个空格。
input ---> "H€ELLOŠŠŠŠWorld$"
output --> "H ELLO World$"
NB: $ is special character that has ASCII<128 注意:$是具有ASCII <128的特殊字符
To know ASCII<128 characters http://www.ascii-code.com/ 要了解ASCII <128个字符的http://www.ascii-code.com/
Please try the following: 请尝试以下操作:
var re = new Regex(@"[\u0080-\uFFFF]");
var s = re.Replace("H€ELLOŠŠŠŠWorld. This is a sample 1234 $.", " ");
Console.WriteLine(s);
OUTPUT OUTPUT
H ELLO World. This is a sample 1234 $.
Why bother with regexes for this task? 为什么要为正则表达式打扰呢?
var str = "H€ELLOŠŠŠŠWorld$";
var sb = new StringBuilder(str.Length);
foreach(var c in str)
sb.Append(c <= 128 ? c : ' ');
var result = sb.ToString();
