我正在实现一个自定义哈希函数,如果我在HashMap桶中发生了多次冲突,我怎么知道桶中存储了多少元素？

假设我有这种结构,

[StructLayout(LayoutKind.Explicit)]
public struct Chapter4Time
{
    [FieldOffset(0)]
    public UInt16 Unused;
    [FieldOffset(2)]
    public UInt16 TimeHigh;
    [FieldOffset(4)]
    public UInt16 TimeLow;
    [FieldOffset(6)]
    public UInt16 MicroSeconds;
}

而这个结构.

[StructLayout(LayoutKind.Explicit)]
public struct IEEE_1588Time
{
    [FieldOffset(0)]
    public UInt32 NanoSeconds;
    [FieldOffset(4)]
    public UInt32 Seconds;
}

我如何从一个结构转换到另一个结构？
