How do you find only properties that have both a getter and setter?

Question

C#, .NET 3.5

I am trying to get all of the properties of an object that have BOTH a getter and a setter for the instance. The code I thought should work is

PropertyInfo[] infos = source.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public | BindingFlags.SetProperty | BindingFlags.GetProperty); 

However, the results include a property that does not have a setter. To give you a simple idea of my inheritance structure that might be affecting this (though I don't know how):

public interface IModel {     string Name { get; } }  public class BaseModel<TType> : IModel {     public virtual string Name { get { return "Foo"; } }      public void ReflectionCopyTo(TType target)     {         PropertyInfo[] infos = this.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public | BindingFlags.SetProperty | BindingFlags.GetProperty);         foreach (PropertyInfo info in infos)             info.SetValue(target, info.GetValue(this, null), null);     } }  public class Child : BaseModel<Child> {     // I do nothing to override the Name property here } 

I end up with the following error when working with Name:

System.ArgumentException: Property set method not found. 

EDIT: I would like to know why this does not work, as well as what I should be doing to not get the error.

Answer 1

Call GetGetMethod and GetSetMethod on the property - if both results are non-null, you're there :)

(The parameterless versions only return public methods; there's an overload with a boolean parameter to specify whether or not you also want non-public methods.)
