c# - Linq 查询 : does this array contain this string?

Question

有更好的方法吗？

    public bool IsServiceRunning(string serviceName)
    {
        string[] services =  client.AllServices();
        return (from s in services
                where s.Equals(serviceName, StringComparison.InvariantCultureIgnoreCase)
                select s).Count() > 0;
    }

比较中不区分大小写很重要。

Answer 1

使用 Any linq扩展方法:

public bool IsServiceRunning(string serviceName)
{
    string[] services =  client.AllServices();
    return services.Any(s => 
        s.Equals(serviceName, StringComparison.InvariantCultureIgnoreCase));
}

这种方式一旦找到匹配项，就会停止执行。
