Question

StackOverflow user jolson had a very nice piece of code that exemplifies how one can register menthods without using strings, but expression trees here.

Is it possible to have something similar for properties instead of methods? To pass a property (not the name of the property) and inside the method to obtain the property name?

Something like this:

     RegisterMethod(p => p.Name)      void RegisterMethod(Expression??? propertyExpression) where T : Property ???     {         string propName = propertyExpression.Name;     } 

Thanks.

You can write something along this:

static void RegisterMethod<TSelf, TProp> (Expression<Func<TSelf, TProp>> expression) {     var member_expression = expression.Body as MemberExpression;     if (member_expression == null)         return;      var member = member_expression.Member;     if (member.MemberType != MemberTypes.Property)         return;      var property = member as PropertyInfo;     var name = property.Name;      // ... }
