I'm still learning ASP.NET and I often see code like this throughout parts of our framework:
我还在学习ASP.NET,我经常在框架的各个部分看到这样的代码:
Public MustInherit Class DBFileManager(Of F As IDBFile, FC As IDBFileContent, FT As IDBFileThumb)
Can anybody tell me what this means? Much thanks!
谁能告诉我这意味着什么?非常感谢!

Its a generic. That means a DBFileManager can be created that acts on 3 classes that implement the 3 named Interfaces
它是通用的。这意味着可以创建一个DBFileManager,它对3个实现3个命名接口的类起作用

To build on what @Jimmy said: It is also an Abstract Class, which means it acts as a base class - you can't use it directly, you must sub class it to use. That subclass must implement the 3 types in the class header.
构建@Jimmy所说的:它也是一个抽象类,这意味着它充当基类 - 你不能直接使用它,你必须对它进行子类化才能使用它。该子类必须在类头中实现3种类型。
