C# linq 分组 排序 把数据放到一个对象中

 DataSet ds = new DataSet();
            ds.ReadXml(flieurl);
            DataTable dt = ds.Tables["loginfo"];

            var querdataset =  from item in dt.AsEnumerable()
                               group item["logip"] by //分组
                              item["logip"] into newGroup//分组key放到 newGroup 中
                               orderby newGroup.Count() descending
                               select new ipcount{coungt=newGroup.Count(),ip=newGroup.Key.ToString()};
            dataGridView1.DataSource = querdataset.ToList();

 

 

 

ipcount  是个类

[Serializable]
    public class ipcount
    {
       
      public  string ip { get;set;}
      public int coungt { get; set; }
    }
