从.NET程序集中获取ProgID(Get ProgID from .NET Assembly)

从.NET程序集中获取ProgID(Get ProgID from .NET Assembly)

我想编写一个程序来查找所有可见的.NET类，以及它们来自.NET程序集的ProgID。 最好的方法是什么？

I want to write a program to find all the com visible .NET classes, and their ProgIDs from a .NET assembly. What's the best way to do this?

这将获得ProgId而不是ClassId，并且如果整个程序集标记为可见，则也可以工作：

Assembly assembly = Assembly.LoadFile("someassembly.dll"); bool defaultVisibility; object[] assemblyAttributes = assembly.GetCustomAttributes(typeof(ComVisibleAttribute),false); if (assemblyAttributes.Length == 0) defaultVisibility = false; else defaultVisibility = (assemblyAttributes[0] as ComVisibleAttribute).Value; foreach(Type type in assembly.GetTypes()) { bool isComVisible = defaultVisibility; object []attributes = type.GetCustomAttributes(typeof(ComVisibleAttribute),true); if (attributes.Length > 0) isComVisible = (attributes[0] as ComVisibleAttribute).Value; if (isComVisible) { attributes = type.GetCustomAttributes(typeof(ProgIdAttribute),true); if (attributes.Length >0) { Console.WriteLine(String.Format("Type {0} has ProgID {1}",type.Name,(attributes[0] as ProgIdAttribute).Value)); } } }

This will get the ProgId rather than the ClassId, and also work if the whole assembly is marked visible:

Assembly assembly = Assembly.LoadFile("someassembly.dll"); bool defaultVisibility; object[] assemblyAttributes = assembly.GetCustomAttributes(typeof(ComVisibleAttribute),false); if (assemblyAttributes.Length == 0) defaultVisibility = false; else defaultVisibility = (assemblyAttributes[0] as ComVisibleAttribute).Value; foreach(Type type in assembly.GetTypes()) { bool isComVisible = defaultVisibility; object []attributes = type.GetCustomAttributes(typeof(ComVisibleAttribute),true); if (attributes.Length > 0) isComVisible = (attributes[0] as ComVisibleAttribute).Value; if (isComVisible) { attributes = type.GetCustomAttributes(typeof(ProgIdAttribute),true); if (attributes.Length >0) { Console.WriteLine(String.Format("Type {0} has ProgID {1}",type.Name,(attributes[0] as ProgIdAttribute).Value)); } } }
