C# Properties (Get and Set)

Properties in C# provide controlled access to class fields.
They are special methods called getters and setters that allow you to read and write data safely.

🔹 Basic Property Syntax

class Person
{
private string name; // private field

public string Name // property
{
get { return name; } // getter
set { name = value; } // setter
}
}




Person p = new Person();
p.Name = "Vipul"; // Calls set
Console.WriteLine(p.Name); // Calls get

class Person

{

private string name; // private field

public string Name // property

{

get { return name; } // getter

set { name = value; } // setter

}

Person p = new Person();

p.Name = "Vipul"; // Calls set

Console.WriteLine(p.Name); // Calls get

🔹 Auto-Implemented Properties

Simpler syntax without explicit field:

🔹 Read-Only Property

Use only get to make property read-only:

✔ Can be initialized in constructor.

🔹 Write-Only Property

Use only set to make property write-only:

🔹 Property with Logic

You can add validation or computation in get/set:

🔹 Expression-Bodied Properties (C# 6+)

🔹 Benefits of Properties

✔ Encapsulate fields
✔ Add validation logic
✔ Control read/write access
✔ Improve code readability

🔹 Common Mistakes

❌ Making fields public instead of properties
❌ Forgetting to use value in setter
❌ Accessing private fields directly from outside

🔹 Summary

Properties are accessors for fields
Use get to read and set to write
Supports validation, read-only, write-only, computed values
Auto-implemented properties simplify code
