C#
string myString = @"'Key:Apple
'Key:Apple123";
string pattern = "('Key:Apple)|('Key: Apple)";
int count = Regex.Matches(myString, pattern).Count;
Console.WriteLine(count); //displaying count as 2
Console.ReadLine();
我只搜索Apple(而不是Apple123),但仍然是2。我如何只搜索特定单词“ Apple”,然后显示为1?
我尝试了以下方法:
string myString = @"'Key:Apple
'Key:Apple123";
string pattern = "(\\b'Key:Apple\\b)|(\\b'Key: Apple\\b)";
int count = Regex.Matches(myString, pattern).Count;
Console.WriteLine(count); //displaying count as 0
Console.ReadLine();
使用上述方法,我们将计数设为零。
请咨询。谢谢!

替换您的图案:
string pattern = @"(Key:\bApple\b)|(Key: \bApple\b)";
\b
会检查单词边界,并能够在您的示例中将count评估为1。
