C# Partial Class Meaning

C# Partial Class is a special feature of C# that incorporates a special feature to implement the functionality of a single class into several files which are united into a single unit as a class file when the specific application is compiled. 

In simple words, C# – Partial Classes and Methods allows the programmer to split the implementation of a class. A programmer programming in C# can gain the advantage of working much faster and on a smoother-scale by splitting the definition of a class over various source files.

Such source files may have a section of the definition of class. Here, all such parts are joined or combined when the final application is compiled. 

It usually contains a partial method. 

Significant Points of C# Partial Class

• The practical utility of it arises when a programmer, working on a large project, requires a split class definition.
• This is beneficial for developing programmes as partial keywords can be applied to specify other parts of the same class identifiable by its namespace.
• In the partial method, the following things are important: partial keyword, return type void, implicitly private and it cannot be virtual.
• A separate file with a .cs extension is important as every class in C# resides there.
• A programmer can take the help of a partial modifier to a class, interface, or structure.

The Conclusion:

In C#partial class several developers can function in one run time with a single class in separate files. And each code can be added to their respective class without any need to recreate or freshly generate the source file.
