Question

I have a class with a property like this:

public class MyClass
{
   private int MyProp { get; set; }

and several methods that use MyProp. One methods sets it and all other methods read the value. What I’d like to do is once the value is set, make it so that other methods can’t change its value.

Thanks for your suggestions.

Answer 1

You can add a private field that is set when the property value changes:

public class MyClass
{
    private bool myPropSet = false;

    private int myProp;
    public int MyProp
    {
        get
        {
            return myProp;
        }
        set
        {
            if (!myPropSet)
            {
                myPropSet = true;
                myProp = value;
            }
        }
    }
