No it is not possible. When the assembly is compiled the class needs to be finished.

blocks|key|912212|text|不是的。分部类是一种纯语言特性。编译程序集时，将组合这些文件以创建该类型。不可能将这些文件展开到不同的程序集中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|912213|不过，根据您想要做的事情，您也许能够使用extension+methods来完成所需的任务。|offset|length|912214|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/bb383977.aspx^0|0|K|H|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

No. Partial classes are a purely language feature. When an assembly is compiled, the files are combined to create the type. It isn't possible to spread the files out into different assemblies.

Depending on what you want to do, though, you might be able to use <a href="http://msdn.microsoft.com/en-us/library/bb383977.aspx" rel="noreferrer">extension methods</a> to accomplish what you need.

blocks|key|912227|text|问题是，为什么要在另一个程序集中创建一个分部类？您可以跨程序集定义抽象类和接口，也许您需要研究一下这一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|912228|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The question is why would you want to make a partial class in another assembly? You can define abstract classes and interfaces across assemblies, maybe you need to look into that.

blocks|key|912255|text|当您要将方法添加到不同dll中的类时，可以使用扩展方法。这种方法的一个缺点是你不能添加静态方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|912256|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You can use extension methods when you want to add a method to a class in a different dll.
The one drawback of this method is that you cant add static methods.

blocks|key|1127312|text|虽然其他答案确实提供了令人不快的“不”，这是任何人在这个页面上都不想看到或听到的，但我被另一个还没有在这里提到的想法所震撼。如果允许跨程序集使用分部类，则可以访问不是由他编写的现有类型的私有成员，从而允许他以原始作者不想要的方式操作它们，从而危及所有继承类的功能。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1127313|不仅如此，其他程序集中的那些类(以及它们的子类)需要重新编译才能正常工作。因此，在逻辑上不可能允许将一个类拆分到不同的程序集中。|1127314|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

While other answers do provide the unpleasant "No" that anyone landing on this page didn't want to see or hear, I was struck by another thought that hasn't been mentioned here yet. If partial classes were allowed across assemblies, one would get access to private members of existing types that were not written by him, thus allowing him to manipulate them in ways that were not intended by the original author, thus jeopardizing the functionality of all inheriting classes too.

Not only that, those classes in other assemblies (and their children) would need to be recompiled to make it work. Thus it is logically not possible to allow splitting a class over different assemblies.

blocks|key|1127343|text|您可能只想在自己的库中创建一个包装器类，围绕第三部分库中的类。然后向包装器类添加任何功能。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1127344|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You probably just want to create a Wrapper class within you own library, around the class in the 3rd part library. Then add whatever functionality to the wrapper class.

Is it possible to have two parts (same namespace, same class name) to a partial class in separate DLLs?

Partial classes in separate dlls

在不同的DLL中，一个分部类可以有两个部分(相同的名称空间，相同的类名)吗？
