Partial classes C# with Example

Partial classes provide an ability to split class declaration (usually into separate files). A common problem that can 
be solved with partial classes is allowing users to modify auto-generated code without fearing that their changes 
will be overwritten if the code is regenerated. Also multiple developers can work on same class or methods. 
using System; 
namespace PartialClassAndMethods 
{ 
public partial class PartialClass 
{ 
public void ExampleMethod() { 
Console.WriteLine("Method call from the first declaration."); 
} 
} 
public partial class PartialClass 
{ 
public void AnotherExampleMethod() 
{ 
Console.WriteLine("Method call from the second declaration."); 
} 
} 
class Program 
{ 
static void Main(string[] args) 
{ 
PartialClass partial = new PartialClass(); 
partial.ExampleMethod(); //  outputs  "Method  call from  the  first declaration." 
partial.AnotherExampleMethod(); // outputs "Method call from the second declaration." 
} 
} 
}
