先写一个静态类:

    /// <summary>
/// 公用基础函数库
/// <remarks>作者: YangYxd</remarks>
/// </summary>
public static class Common {
/// <summary>
/// 返回一个以毫秒为单位的时间 (0001-01-01 00:00:00.000 算起)
/// </summary>
public static long Ticks {
get {
return (long) (System.DateTime.UtcNow.Ticks * 0.0001f) ;
}
} public delegate bool CondDelegate(); /// <summary>
/// 等待指定的毫秒
/// </summary>
public static IEnumerator WaitForMillis(long millis, CondDelegate cond = null) { }
}

调用方法:

yield return Common.WaitForMillis ();
