C Sharp (C#) - Properties and Encapsulation

Identify the error in this property setter code:

private string name;
public string Name {
  get { return name; }
  set {
    if (value == null || value == "")
      throw new ArgumentException("Name cannot be empty");
    name = value;
  }
}

AThe setter does not assign the value to the field

BThe setter should use 'value.Equals("")' instead of 'value == ""'

CThe setter does not check for whitespace-only strings

DThe setter should not throw exceptions in property setters

Step-by-Step Solution

Solution:

Step 1: Review validation logic
The setter checks if value is null or empty string but does not check if value is whitespace only.
Step 2: Understand missing validation
Strings like " " (spaces) pass the check but are usually invalid for a name.
Final Answer:
The setter does not check for whitespace-only strings -> Option C
Quick Check:
Missing whitespace check in setter validation [OK]

Quick Trick: Check for whitespace with string.IsNullOrWhiteSpace [OK]
