Question

Given this class:

public class MyClass
{
    public int MyProperty {get; set;}
}

How will I be able to extract the name of MyProperty in code?

For example, I am able to get the name of the class like this

typeof(MyClass).Name

How can I do something similar for the property?

The reason for the question is that I want this particular code to be resistant against refactorizations of the names.

EDIT: With resistant I mean that I want the code at the call site to be robust in the face of changes of the propertyname. I have some stuff that is using a string representation of the property name. Sorry for the poor phrasing.
I did not include call site code in order to keep the problem clean and not wander off into other discussions on the nature of the call site code.

You do it like this, using compiler generated expression trees:

public static string GetMemberName<T, TValue>(Expression<Func<T, TValue>> memberAccess)
{
    return ((MemberExpression)memberAccess.Body).Member.Name;
}

Now call the static method from code:

class MyClass
{
    public int Field;
    public string Property { get; set; }
}

var fieldName = GetMemberName((MyClass c) => c.Field);
var propertyName = GetMemberName((MyClass c) => c.Property);
// fieldName has string value of `Field`
// propertyName has string value of `Property`

You can now also use refactoring to rename that field without breaking this code
