简述：DataGrid控件显示List集合数据信息，将开始、结束时间、其他查询字段通过POST接口获取接口返回的List集合数据；代码如下：

DataGrid列表页：

 private void BindData()
 {
     Dictionary<string, string> addParames = new Dictionary<string, string>();
    
     addParames.Add("beginDate", begin_date.SelectedDate.Value.ToString("yyyy-MM-dd"));

     addParames.Add("endDate", end_date.SelectedDate.Value.AddDays(1).ToString("yyyy-MM-dd"));

     addParames.Add("ChePai", chepai.Text.Trim());

     addParames.Add("Lydh", lydh.Text.Trim());

     try
     {
         string PostUrl = "http://192.168.1.150:8089/api/RiZhi/GetRiZhiInfoByModel";
         string sendData = JsonConvert.SerializeObject(addParames);//发送集合
         RecordLog(sendData);
         string resultData = Post(sendData, PostUrl);
         List<Sys_RiZhi> riZhiList = JsonConvert.DeserializeObject<List<Sys_RiZhi>>(resultData);//josn集合转成list集合
         dataGrid1.ItemsSource = riZhiList;
         //RecordLog(resultData);

     }
     catch (Exception ex)
     {
         MessageBox.Show(string.Format("局域网链接失败：{0}", ex.Message));
        
     }
 }

接口：

public List<RiZhi> GetRiZhiInfoByModel(dynamic myRequest)
{
    DateTime begin_date = DateTime.Now;
    DateTime endDate_date = DateTime.Now;
    if (!string.IsNullOrEmpty(myRequest.beginDate.ToString())) { begin_date = Convert.ToDateTime(myRequest.beginDate.ToString()); }
    if (!string.IsNullOrEmpty(myRequest.endDate.ToString())) { endDate_date = Convert.ToDateTime(myRequest.endDate.ToString()); }

    string sqlStr = "select * from Sys_RiZhi where CreateTime>='" + begin_date.ToString("yyyy-MM-dd") + "' and CreateTime<='" + endDate_date.AddDays(1).ToString("yyyy-MM-dd") + "'";

    if (!string.IsNullOrEmpty(myRequest.ChePai.ToString()))
    {
        sqlStr += " and ChePai like '%" + myRequest.ChePai + "%'";
    }

    if (!string.IsNullOrEmpty(myRequest.Lydh.ToString()))
    {
        sqlStr += " and Lydh like '%" + myRequest.Lydh + "%'";
    }

    DataTable dt = SQLiteHelper.ExecuteDataTable(sqlStr, null);

    List<RiZhi> riZhiList = SQLiteHelper.ToList<RiZhi>(dt);

    return riZhiList;
}
