因为nobugz说，你不能明确实现IDisposable。

As nobugz says, you can't explicitly implement IDisposable.

所以，假设你的问题的标题是准确的，你想明确实现接口成员（或在C ++ / CLI中支持的显式覆盖，但我不认为在C＃中可能，C ++ / CLI还提供更多的灵活性来覆盖具有相同功能的多个v表槽），参见：

So, assuming that the title of your question is accurate, and you want to have explicit implementation of interface members (or explicit overrides which are supported in C++/CLI but I don't think are possible in C#, C++/CLI also provides more flexibility to override multiple v-table slots with the same function), see:
