what are partial classes and their use?..

This is a feature of 2005,when we have large and unwildly
classes instead of writing all the methods in same program
we will divide the class into number of programs with the
same class name,these classes are preceeded with partial
keyword,when we compile all this partial classes only one
dll with the same class name will be created.

class with some 20 methods:
Example.cs
class classA{
m1( );
m2( );
.
.
.
m20( );
}

Apply partial concept:

Example1.cs
partial class classA
{
m1( );
m2( );
.
.
m8( );
}
example2.cs
partial class classA
{
m9( );
m10( );
.
.
m15( );
}
Example3.cs
partial class classA
{
m16( );
.
.
m20( );
}

if we compile Examle1.cs,Example2.cs,Example3.cs it will
create only one dll

Answer / vikas kant

Partial Class is the class whose definition is present in
two or more files.All these files combined with each other
at the compile time.
e.g :---

public partial class Employee
{
public void DoWork()
{
}
}

public partial class Employee
{
public void GoToLunch()
{
}
}

so while using the partial classes coders can work in
different files and at compile time all the code can be
combined.it saves the time and also provides the better
security bcoz code is present in more than one file.

Answer / arunajyothi.m

“partial” keyword can be used to split a single class,
interface, or struct into multiple, separate files in
ASP.NET (using C# as the language). This permits multiple
developers to works on these files, which can later be
treated as a single unit by the compiler at the time of
compilation and compiled into MSIL code.

1.Partial classes can improve code readability and
maintainability by providing a powerful way to extend the
behavior of a class and attach functionality to it.

2.The partial modifier can only appear immediately before
the keywords class, struct, or interface.

3.Nested partial types are allowed in partial-type
definitions.

4.Using partial classes helps to split your class
definition into multiple physical files.

5.Note that the partial keyword applies to classes,
structs, and interfaces, but not enums
