vb.net实现一个自定义类数组的排序

今天下午做东西时遇到这样的问题：

把公司所有员工的业绩（回访数量，收费情况）用一个柱型图表示出来，要求：

A：Y轴表示公司的所有员工且业绩为0的员工不显示出来，X轴表示业绩数量（回访数量+收费情况）；

B：按要求对柱图实现升序或着降序

按以上要求所得思路为：

首先建立一个类（也可以通过结构来实现），类中包含的属性（或字段）为员工ID属性（或字段），员工回访数量属性（或字段），员工收费情况属性（或字段），员工业绩属性等等。（为了能利用Array中的sort需要实现一个接口，会在原码中说明）

接着通过一个table来通过颜色或着图片表现出来。下面是实现的原码：

Public Class wordload
    Implements IComparable'一定要实现这个接口，才能利用下面的：Array.Sort
    Public pay As Integer '维护数量
    Public go_back As Integer '回访数量
    Public name As String '用户名称
    Public total_ As Integer '维护数量+回访数量

'以下是想通过那个属性（或字段），来进行排序
    Public Function CompareTo(ByVal obj As Object) As Integer Implements System.IComparable.CompareTo
        Dim other As wordload = CType(obj, wordload)
        Return total_.CompareTo(other.total_)
    End Function

    Public Sub New(ByVal pay_value As Integer, ByVal go_back_value As Integer, ByVal name_value As String)
        pay = pay_value
        name = name_value
        go_back = go_back_value
        total_ = pay + go_back
    End Sub
End Class

Public Sub creat_test(ByVal myarr() As wordload, ByVal mytable As System.Web.UI.WebControls.Table)
        Array.Sort(myarr)'说明利用Array进行排序
        Dim rows_num As Integer = myarr.Length + 1 '说明：人员做为y轴，即人员的个数做为行数，其中为了写表头，要加一行，所以表的总行数为，人员个数+1
        Dim total_comm_num As Integer = myarr(myarr.Length - 1).total_ '说明：列数为工作量加1，因为人员的名字要占一列
        Dim pay_width As Integer '定义维护宽度
        Dim go_back_width As Integer '定义回访宽度
        Dim myimage As HtmlControls.HtmlImage
        Dim myspan As HtmlControls.HtmlGenericControl

        Dim begin_myrow As New Web.UI.WebControls.TableRow

        mycell1.BackColor = mycol1.Green
        mycell1.Style.Add("BACKGROUND-COLOR", "#949294")
        mycell1.Style.Add("FONT-WEIGHT", "bold")
        mycell1.Style.Add("FONT-SIZE", "18pt")
        mycell1.Style.Add("COLOR", "#ffffff")
        mycell1.Width = WebControls.Unit.Pixel(60)
        begin_myrow.Cells.Add(mycell1)
        begin_myrow.Width = Unit.Pixel(700)
        For b As Integer = 0 To 7 '写第一行的列
            Dim mycol As New Color
            If b = 0 Then
                Dim mycell As New UI.WebControls.TableCell
                'mycell.BackColor = mycol.LightGreen
                begin_myrow.Cells.Add(mycell)
            Else
                myspan = New HtmlControls.HtmlGenericControl
                myspan.InnerText = ((total_comm_num * (b - 1) / 7) \ 1).ToString
                myspan.Style.Add("WIDTH", "80px") 'WIDTH: 100px;
