WPF 怎么将查询出来的几个值绑定到 telerik:RadGridView 上显示出来

页面代码 ：
TextAlignment="Center"
DataMemberBinding="{Binding Query_TC}"
IsReadOnly="True"/>
TextAlignment="Center"
DataMemberBinding="{Binding Query_MC}"
IsReadOnly="True"/>
TextAlignment="Center"
DataMemberBinding="{Binding Query_QC}"
IsReadOnly="True"/>

后台代码：
public class Query
{
public string Query_NAME { get; set; }
public long Query_TC { get; set; }
public long Query_MC { get; set; }
public long Query_QC { get; set; }
public long Query_WC { get; set; }
public long Query_CC { get; set; }
public long Query_EC { get; set; }
public long Query_PC { get; set; }
}

    //public void Query()
    //{
    //    DataTable dt = new DataTable();
    //    DataColumn dc1 = new DataColumn("NAME", Type.GetType("System.String"));
    //    DataColumn dc2 = new DataColumn("TC", Type.GetType("System.Int16"));
    //    DataColumn dc3 = new DataColumn("MC", Type.GetType("System.Int16"));
    //    DataColumn dc4 = new DataColumn("QC", Type.GetType("System.Int16"));
    //    DataColumn dc5 = new DataColumn("WC", Type.GetType("System.Int16"));
    //    DataColumn dc6 = new DataColumn("CC", Type.GetType("System.Int16"));
    //    DataColumn dc7 = new DataColumn("EC", Type.GetType("System.Int16"));
    //    DataColumn dc8 = new DataColumn("PC", Type.GetType("System.Int16"));
    //    dt.Columns.Add(dc1);
    //    dt.Columns.Add(dc2);
    //    dt.Columns.Add(dc3);
    //    dt.Columns.Add(dc4);
    //    dt.Columns.Add(dc5);
    //    dt.Columns.Add(dc6);
    //    dt.Columns.Add(dc7);
    //    dt.Columns.Add(dc8);
    //}

    public void QueryInventoryInfo(string areaId)
    {
        Query qu = new Query();
        string locType = "2";
        qu.Query_TC = this.WMSServiceContext.MD_LOCATION.Where(c => c.LOC_TYPE != locType && c.AREA_ID.StartsWith(areaId)).LongCount();
        qu.Query_MC = this.WMSServiceContext.MD_LOCATION.Where(c => c.LOC_TYPE != locType && c.AREA_ID.StartsWith(areaId)
                                                                 && c.STATUS.Contains("m")).LongCount();
        qu.Query_QC = this.WMSServiceContext.MD_LOCATION.Where(c => c.LOC_TYPE != locType && c.AREA_ID.StartsWith(areaId)
                                                                 && c.STATUS.Contains("q")).LongCount();
        qu.Query_WC = this.WMSServiceContext.MD_LOCATION.Where(c => c.LOC_TYPE != locType && c.AREA_ID.StartsWith(areaId)
                                                                 && c.STATUS.Contains("w")).LongCount();
        qu.Query_CC = this.WMSServiceContext.MD_LOCATION.Where(c => c.LOC_TYPE != locType && c.AREA_ID.StartsWith(areaId)
                                                                 && c.STATUS.Contains("c")).LongCount();
        qu.Query_EC = this.WMSServiceContext.MD_LOCATION.Where(c => c.LOC_TYPE != locType && c.AREA_ID.StartsWith(areaId)
                                                                 && c.STATUS.Contains("e")).LongCount();
        qu.Query_PC = this.WMSServiceContext.MD_LOCATION.Where(c => c.LOC_TYPE != locType && c.AREA_ID.StartsWith(areaId)
                                                                 && c.STATUS.Contains("p")).LongCount();
    }

Query是自己建的实体类 qu.Query_TC 、qu.Query_MC .... 接收了查询结果。刚开始是想绑定实体类
