使用C#,如何在文本块中搜索和输入超链接?

"(http://([^ ]+))" 具有 "<a href=\"$1\">$2</a>"

  string input = "Why don't you use http://www.google.com for that?";
  string pattern = "(http://([^ ]+))";
  string replacement = "<a href=\"$1\">$2</a>";
  Regex rgx = new Regex(pattern);
  string result = rgx.Replace(input, replacement);
  Console.WriteLine("Original String: {0}", input);
  Console.WriteLine("Replacement String: {0}", result)

使用正则表达式。您可以在此处找到表达式: http://regexlib.com/Search.aspx?k=url

然后这样做:

Regex regex = new Regex("YOUR PATTERN");
regex.Replace(
   textBlock, 
   delegate (Match m) { 
       return string.Format(@"<a href=""{0}"">{0}</a>", m.Groups[0]); 
   });

注意,您应该用符合您需要的正则表达式替换“您的模式”。
