Question

I would expect there to be three lines of output from this code, but there are none:

[AttributeUsage( AttributeTargets.Property )]
public class FieldAttribute : System.Attribute
{
  public String FieldName
  {
    get;
    set;
  }
}

public class Host
{

  [Field]
  public String FieldOne
  {
    get;
    set;
  }

  [Field(FieldName="Foo")]
  public String FieldTwo
  {
    get;
    set;
  }

  [FieldAttribute]
  public String FieldThree
  {
    get;
    set;
  }

  public String FieldFour
  {
    get;
    set;
  }
}


class Program
{
  static void Main( string[] args )
  {
    Type t = typeof(Host);
    foreach ( Object att in t.GetCustomAttributes( typeof(FieldAttribute), true ) )
    {
      Console.WriteLine( att.ToString() );
    }
  }
}

Am I missing soemthing obvious?

Answer 1

t.GetCustomAttributes returns the attributes declared on the class itself.

You need to loop through t.GetProperties() and call GetCustomAttributes on the individual PropertyInfos.
