What is Partial Class and its uses?

Answer:

With partial, we can physically separate a class into multiple files.

It is true that Partial Class is used in auto code generation, one use can be maintaining a large class file which might have thousand lines of code. The class might end up with 10 thousand lines and we don't want to create a new class with different name.

public partial class Product


{

// 20 business logic embedded in methods and properties..

}



public partial class Product

{

// another 30 business logic embedded in methods and properties..

}

//finally compile with product.class file.



Another possible use could be that more than one developer can work on the same class as they are stored at different places.
