Can partial classes be in different assemblies?
No, you cannot have two partial classes referring to the same class in two different assemblies (projects). Once the assembly is compiled, the meta-data is baked in, and your classes are no longer partial. Partial classes allows you to split the definition of the same class into two files.
What are partial classes?
Partial classes are portions of a class that the compiler can combine to form a complete class. Although you could define two or more partial classes within the same file, the general purpose of a partial class is to allow the splitting of a class definition across multiple files.
Why would you use partial classes?
Partial Classes
- When working on large projects, spreading a class over separate files enables multiple programmers to work on it at the same time.
- When working with automatically generated source, code can be added to the class without having to recreate the source file.
Can partial class be inherited?
Inheritance cannot be applied to partial classes.
In what scenarios do we use partial classes?
The biggest use of partial classes is in technologies where there is code generation. The Microsoft team themselves use partial classes in ASP.NET, LINQ, and EF code generation. For instance, when we look at ASP.NET there are two parts, one is the auto-generated code of a page and the other is the code you write.
Do partial classes have to be in the same namespace?
All parts of a partial class should be in the same namespace. Each part of a partial class should be in the same assembly or DLL, in other words you can’t create a partial class in source files of a different class library project. Each part of a partial class has the same accessibility.
What is a partial class and what are its advantages?
With partial classes, we can spread the definition of a class over multiple files. Partial classes attempt to solve the problem of separation of designer code and implementation code. In Whidbey, partial classes are used to separate these ideas by having the designer code in one file, and the user code in another.
Can partial classes be in different namespaces?
All parts of a partial class should be in the same namespace. Each part of a partial class should be in the same assembly or DLL, in other words you can’t create a partial class in source files of a different class library project.
Can we create object of partial class?
Can we create Object of partial class?
Is a partial class an abstract class?
An abstract class is a class with at least one method defined as abstract. This type of class cannot be instantiated. An abstract class can have one or more abstract methods and properties and other methods and properties like normal classes. A class defined in two or more files is called a partial class.
