what is the concept of partial class in .net2.0?

Partial class allows developers to split a class into multiple files.


ex:

public partial class A
{
    A()
   
    {
        //constructor here

    }

}

Suppose another developer needs to add a new function to it called updated A , the other developer can creat a new file call it A1.cs and it should be look something like this.

public partial cllass A

{
  public void update A()
  {
     // function code goes here
    }
}


while using partial classes ,if we have declared a constructor or a function in one source file, we can not define the same in the other partial source file.

  The .NET runtime executes  these two classes it treats  two or multiple source file as one single class A.
