删除字符串中的空格

Question

嘿伙计们，我有这样的字符串

  

“THIS_的 ___ is_a _ _string。”

，我想把所有多个空格都变成一个。 C＃中是否有任何可以执行此操作的功能？

谢谢

Answer 1

var s = "This   is    a     string    with multiple    white   space";

Regex.Replace(s, @"\s+", " "); // "This is a string with multiple white space"

Answer 2

Regex r = new Regex(@"\s+");
string stripped = r.Replace("Too  many    spaces", " ");

Answer 3

这是没有正则表达式的好方法。有了Linq。

var astring = "This           is      a       string  with     to     many   spaces.";
astring = string.Join(" ", astring.Split(' ').Where(m => m != string.Empty));

输出"This is a string with to many spaces"

Answer 4

此页面上的正则表达式示例可能不错，但这是一个没有正则表达式的解决方案：

string myString = "This   is a  string.";
string myNewString = "";
char previousChar = ' ';
foreach(char c in myString)
{
  if (!(previousChar == ' ' && c == ' '))
    myNewString += c;
  previousChar = c;
}
