关键代码：

        public static void Bind<T>(this RepositoryItemComboBox combox, ICollection source)        {            /*说明：             *所涉及的列叙设定FieldName，否则会出现无法选中的问题；             *eg:             *List<PersonInfo> _source = new List<PersonInfo>();             *_source.Add(new PersonInfo("Sven", "Petersen"));             *_source.Add(new PersonInfo("Cheryl", "Saylor"));             *_source.Add(new PersonInfo("Dirk", "Luchte"));             *repositoryItemComboBox1.Bind<PersonInfo>(_source);              */            if (source != null)            {                try                {                    combox.BeginUpdate();                    combox.Items.AddRange(source);                    combox.ParseEditValue += combox_ParseEditValue;                }                finally                {                    combox.EndUpdate();                }            }        }        //解决‘对象必须实现iconvertible’问题        private static void combox_ParseEditValue(object sender, ConvertEditValueEventArgs e)        {            e.Value = http://www.mamicode.com/e.Value.ToString();"kwrd">true;        }代码使用：

            string[] test = new string[3] { "aa", "bb", "cc" };            repositoryItemComboBox1.Bind<PersonInfo>(test);
