[mono-cecil] CustomAttributes of Methods

[storki]

Hi!

I'm working with Cecil and .NET CF to implement an OR-Mapper for a
practical exercise during my academic studies.
Everything worked fine, but now I encountered a Problem:

I want to extract all CustomAttributes of an Method, but
MethodDefinition.CustomAttributes always returns an empty
Collection...

Here is what I have done

AttributeClass:

    [AttributeUsage(AttributeTargets.Property, AllowMultiple=true)]
    public class ColumnAttribute : Attribute
    {
        public const string DEFAULTTARGET =
"e6e8fc76-9939-40a2-9ee9-168b8a52bc93";
        private string _columnMapping;
        private string _target;

        public ColumnAttribute() {
            _target = DEFAULTTARGET;
            _columnMapping = null;
        }

        /// <summary>
        /// Initializes a new instance of the <see
cref="ColumnAttribute"/> class.
        /// </summary>
        /// <param name="columnMapping">The name of the column in the
data base.</param>
        public ColumnAttribute(string columnMapping) {
            _target = DEFAULTTARGET;
            ColumnMapping = columnMapping;
        }


        public string Target { get { return _target; } set { _target =
value; } }

        public string ColumnMapping { get { return
this._columnMapping; } internal set { this._columnMapping = value; } }
    }

A Type Using the Attribute:

    public class CollectionEvent : SerializableObject
    {
         ...

        [Column(Target="replication")]
        [Column]
        public int? SeriesID { get { return _SeriesID; } set
{ _SeriesID = value; } }

        ...
     }

And now the Fragment using Cecil
    ...

    _assemby = AssemblyFactory("DivMobi Collection Data Layer.dll");

    foreach(TypeDefinition typeDef in _assembly.MainModule.Types) {
         if(typeDef.Name != "<Module>")
         {
              foreach(MethodDefinition mDef in typeDef.Methods)
              {
                   foreach(CustomAttribute ca in
mDef.CustomAttributes)
                   {
                         //do something with ca ....
                   }
              }
         }
    }

The problem is that no CustomAttribute is returned...

Extracting CustomAttributes of Assemblies and TypeDefinitions works
fine ...

Thanks in advance,
storki!
