某个实体类如下：

public class Trans    {        public int Id { get; set; }        public string TimeStr { get; set; }        public string SeqID { get; set; }        public bool Equals(Trans other)        {            return SeqID.Equals(other.SeqID);        }        //重载自定义类的Equals方法        public override bool Equals(object obj)        {            if (obj is Trans) return Equals((Trans)obj);            return base.Equals(obj);        }    }

List<Trans> list = new List<Trans>();的数据如下

10:00:00   20140504000001
10:00:00   20140504000001
10:00:01   20140504000002
10:00:01   20140504000002
10:00:01   20140504000003
10:00:01   20140504000003
10:01:02   20140504000004
10:01:02   20140504000004
10:10:03   20140504000005
10:10:03   20140504000005

现要去重复，代码如下：

List<Trans> listNew = new List<Trans>();foreach (var x in list){   if (!listNew.Contains(x))   {      listNew.Add(x);   }}

执行结果：

10:00:00   20140504000001
10:00:01   20140504000002
10:00:01   20140504000003
10:01:02   20140504000004
10:10:03   20140504000005
