1.More than one Programmer or developer can simultaneously write the code for class. 2. Partial class allows a clean separation of business logic layer and the user interface.
Microsoft has introduced a new feature in .NET 2.0. 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. At compile time, these files are merged together.
HI,
partical class is a new concept,introduced in .net 2.0.
the purpose of partial class it to make more than one developer to work on same class name prefixing with partial keyword. more than one developer can write code on same class but at runtime complier will make ther class as one entity.
