C#，将时间从 float 表示形式转换为字符串表示形式

Question

我有一个时间表示为 float (以秒为单位)。我需要一个函数来将此表示形式转换为字符串格式。像这样的东西:

    /// <summary>
    /// Get time from a float representation.
    /// </summary>
    /// <param name="f">Time in a floating-point number.</param>
    /// <returns>Time in a string format.</returns>
    string GetTime(float f)
    {
        return f.ToString(); // string format is hh:mm:ss (h-hours, m-minutes, s-seconds)
    }

例如10.0转换为00:00:10，67.0转换为00:01:07

Answer 1

那将是 TimeSpan.FromSeconds :

Returns a TimeSpan that represents a specified number of seconds, where the specification is accurate to the nearest millisecond.
