compiler showing different errors for unassigned struct object field and property

In the below code in line:1, the compiler shows error :"Use of possibly unassigned field 'IntField' " but for line: 2 the error is "Use of possibly unassigned local variable 'structObj' " . Why different error?

class Program
{
    static void Main(string[] args)
    {

        StructA structObj;

        Console.WriteLine(structObj.IntField); //Line :1
        Console.WriteLine(structObj.IntProperty); //Line :2            

        Console.ReadKey();
    }
}


struct StructA
{
    public int IntField;
    public int IntProperty { get; set; }
}
Solution

  • Because StructA is a struct and IntField is a field.

    Try StructA structObj = new StructA() before you use it.

    I think the reason of the difference between the errors is that the property is converted to methods. And calling a method on a not initialize object is not possible.
