ObjectDescriber

Purpose

Small expression-based helpers implemented in ObjectDescriber.cs. Provides GetName(...) overloads that extract member or method names from expression trees.

API

• string GetName(Expression<Action> e)
• string GetName<TResult>(Expression<Func<TResult>> selector)
• string GetName<TArg, TResult>(Expression<Func<TArg, TResult>> selector)
• string GetName<TArg>(Expression<Action<TArg>> selector)

Examples

class Person { public string Name { get; set; } public void Update() { } }

var propName = ObjectDescriber.GetName<Person, string>(x => x.Name); // "Name"
var methodName = ObjectDescriber.GetName(() => new Person().Update()); // "Update"

Remarks

• The helper expects simple member or method call expressions and throws NotSupportedException when passed expressions it cannot analyze.
• Useful in logging, test assertions, and scenarios where code-based member name retrieval avoids string literals.
