C# getter vs readonly

Question

Is there any difference between the following?

class C
{
    // One:
    public static readonly int ValueAsAMember = 42;

    // Two:
    public static int V         


        

Answer 1

Yes, there's a difference between the two.

A readonly field can only be set in the constructor.

A {get; private set;} or just {get;} (for short), can be set at anytime from within the class.

Example:

public class Car
{
    public readonly string Name;

    public string color {get; private set;}

    public Car()
    {
        Name = "Car";
        Color = "Red";
    }

    // will fail compilation
    public void ModifyName()
    {
        Name = "Subaru"
    }

    // perfectly ok
    public void ModifyColor()
    {
        Color = "Green"
    }
}
