Question

Hi I am trying to create the array of a class and assigning values to it’s fields. My code is like

        RecordRef[] referLocation = new RecordRef[1];
        referLocation[0].type = RecordType.location;
        referLocation[0].internalId = "6";

But I am getting Exception Error : Object reference not set to an instance of an object.
What is wrong in the code?

Answer 1

You have created array of RecoredRef objects, but you haven’t created any object inside it.
You need to create instance of objects you want to use:

RecordRef[] referLocation = new RecordRef[1];
// create new instance of RecordRef, which is held inside your array
referLocation[0] = new RecordRef();  
referLocation[0].type = RecordType.location;
referLocation[0].internalId = "6";

You may also use object initializer:

referLocation[0] = new RecordRef
{ 
    type = RecordType.location,
    internalId = "6"
};
