我有以下格式的日志文件:

我尝试的代码是:
StreamReader reader = new StreamReader("test file path");
string x = reader.ReadToEnd();
List<string> users = new List<string>();
int numberOfUsers;
Regex regex = new Regex(@"User:(?<username>.*?) appGUID");
MatchCollection matches = regex.Matches(x);
foreach (Match match in matches)
{
if (!users.Contains(match.ToString())) users.Add(match.ToString());
}
Regex regex2 = new Regex(@"User: (?<username>.*?) appGUID");
matches = regex2.Matches(x);
foreach (Match match in matches)
{
if (!users.Contains(match.ToString())) users.Add(match.ToString());
}
numberOfUsers = users.Count;
Console.WriteLine(numberOfUsers);
// keep screen from going away
// when run from VS.NET`
答案 0 :(得分:2)
见下面的代码:
StreamReader reader = new StreamReader(@"test file path");
string x = reader.ReadToEnd();
List<string> users = new List<string>();
Regex regex = new Regex(@"User:\s*(?<username>.*?)\s+appGUID");
MatchCollection matches = regex.Matches(x);
foreach (Match match in matches) {
var user = match.Groups["username"].Value;
if (!users.Contains(user)) users.Add(user);
}
int numberOfUsers = users.Count;
Console.WriteLine(numberOfUsers);
我做了以下两个修改:
username
组。
