What Is Partial Public Class?


What Is Partial Public Class? A partial class is a special feature of C#. It provides a special ability to implement the functionality of a single class into multiple files and all these files are combined into a single class file when the application is compiled. A partial class is created by using a partial keyword.

What is the meaning of partial class? 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.

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.

Are partial classes useful? The biggest use of partial classes is to make life easier for code generators / designers. Partial classes allow the generator to simply emit the code they need to emit and they do not have to deal with user edits to the file.

What will happen if there is an implementation of partial method without defining partial?

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.
