Linq查询:这个数组是否包含这个字符串？

Question

有一个更好的方法吗？

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

比较中的不区分大小写非常重要.

Answer 1

使用Anylinq扩展方法:

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

这样一旦找到匹配,执行就会停止.

Answer 2

尝试:

return services.Any(s =>
            s.Equals(serviceName, StringComparison.InvariantCultureIgnoreCase));
