How to access protected member in an inherited class

I have 2 classes: 

public class Access
{
    public class Job
    {
        public int Id { get; set; }
        protected string JobName { get; set; }
    }
}

Class2.cs

public class Full: Access.Job
{

}

Full ful = new Full();

Why I'm not able to access the ful.JobName member?

Because You are trying to access protected method from outside the class. Only public methods are available. You can access the property/variably/method that is protected, only in the inherited class, but not from outer code:

public class Full: Access.Job
{
    public void mVoid()
    {
        Console.WriteLine(this.JobName);
    }

    protected void mProtVoid()
    {
        Console.WriteLine(this.JobName);
    }

    private void mPrivateVoid()
    {
        Console.WriteLine("Hey");
    }
}

Full myFull = new Full();
myFull.mVoid();  //will work
myFull.mProtVoid(); //Will not work
myFull.mPrivateVoid(); //Will not work

If You need to get to the protected property, there are 2 ways (3 actually, but Reflection is the dirty way and should be avoided):

1. Make it public

If it will be set to public, it will be stil inherit and You can directly access it:

Full nFull = new Full();
Console.Write(nFull.JobName);

2. Make a "wrapper"/"facade"

Create new property or method, that will just access the hidden property and return it in expected format.

public class Full: Access.Job
{
    public string WrappedJobName { get { return this.JobName; } }
    public string WrappedJobName => this.JobName; //C# 6.0 syntax
}

Full mFull = new Full();
Console.WriteLine(mFull.WrappedJobName);
