override property in csharp

To override a property in C#, you can use the "override" keyword in the derived class to declare a property with the same name and signature as the base class property. Here's an example:

main.cs
public class BaseClass
{
    public virtual int MyProperty { get; set; }
}

public class DerivedClass : BaseClass
{
    private int _myProperty;

    public override int MyProperty
    {
        get { return _myProperty; }
        set { _myProperty = value + 1; }
    }
}

In this example, we have a base class with a virtual property called "MyProperty". The derived class overrides this property by declaring a new property with the same name and signature, and using the "override" keyword to indicate that it is overriding the base class property. The derived class property adds 1 to the value before setting it, effectively overriding the behavior of the base class property.

Note that you can only override virtual or abstract properties in C#, and you must use the same accessibility level in the derived class property as in the base class property. Also, if you're overriding a property with a public get accessor, you must use the "new" keyword instead of "override" if you want to change the accessibility level of the setter.
