本文探讨了当.NET类型尝试访问传统COM类型时，运行时包装类(RCW)如何负责在COM类型和.NET类型间进行翻译。例如，COM SAFEARRAY映射到.NET System.Array类，COM BSTR类型映射到System.String等。同样地，当.NET类型利用传统COM类型时，使用中间COM调用包装类(CCW)进行操作。

When a .NET type attempts to access a legacy COM type, an intermediate object (termed a Runtime Callable Wrapper, or simply RCW) is responsible for translating between COM types and .NET types. For example, COM SAFEARRAY types map into the .NET System.Array class, COM BSTR types map into System.String, and so on. A similar operation occurs when a .NET type makes use of a legacy COM type (using an intervening COM Callable Wrapper, or simply CCW).
