Class Extension D365FO


In this blog I will show you class extension in D365 and add new method in the existing class without any over-layer..


There are two way to create Extension of the existing class...

1. Static Class
2. ExtensionOf

Static class

Create a new public static class use the name pattern ClassName + _Extension

You can use the following code for reference....
publicstaticclassSLD_PaymFee_Extension
{

publicstaticvoid paymfeeFind(PaymFee _this)
{
/// You can write your code here


_this.findFees(); //Use _this to call methods from the base class;
}



}




ExtensionOf

Create new class add the annotation of ExtensionOf and enter the class name... In this type of extension add final keyword.

[ExtensionOf(classStr(PaymFee))]
finalclass SLD_PaymFee_Extension
{

publicstaticvoid paymfeeFind(PaymFee _this)
{
/// You can write your code here


_this.findFees(); //Use _this to call methods from the base class;
}



}


For verification you can use the below code

classSLD_DemoClass
{



publicstaticvoid main(Args _args)
{
PaymFee obj =new PaymFee();
obj.paymfeeFind();
}

}
