C Sharp (C#) - Properties and Encapsulation

Identify the error in this C# code snippet:

class Account {
    private string _pin;
    public string Pin {
        get { return _pin; }
        set { _pin = value; }
    }
}

var acc = new Account();
acc.Pin = "1234";
Console.WriteLine(acc.Pin);

The goal is to make Pin write-only.

AThe private field _pin should be public.

BThe set accessor should return a value.

CThe property has both get and set accessors, so it is not write-only.

DThe property should be static.

Step-by-Step Solution

Solution:

Step 1: Check property accessors
The property has both get and set accessors, allowing reading and writing.
Step 2: Understand write-only requirement
Write-only properties must have only a set accessor and no get accessor.
Final Answer:
The property has both get and set accessors, so it is not write-only. -> Option C
Quick Check:
Write-only = set only, no get [OK]

Quick Trick: Write-only means no get accessor allowed [OK]

Common Mistakes:

MISTAKES

Leaving both get and set for write-only
Changing field visibility instead of property
Expecting set to return a value
