vb.net实现一个自定义类数组的排序

核心提示:今天下午做东西时碰到这样的问题: 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,vb.net实现一个自定义类数组的排序,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
今天下午做东西时碰到这样的问题:   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
     Dim mycell1 As New UI.WebControls.TableCell
     Dim mycol1 As New Color
     mycell1.Text = "员工"
     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;
         myspan.Style.Add("HEIGHT", "40px") ' HEIGHT: 100px;: bold; FONT-SIZE: 18pt;COLOR: #ffffff;
         myspan.Style.Add("BACKGROUND-COLOR", "#949294")
         myspan.Style.Add("FONT-WEIGHT", "bold")
         myspan.Style.Add("FONT-SIZE", "18pt")
         myspan.Style.Add("COLOR", "#ffffff")
         begin_myrow.Cells(1).Controls.Add(myspan)
       End If
     Next
     mytable.Rows.Add(begin_myrow)
     For i As Integer = 0 To rows_num - 2
       pay_width = (500 * myarr(i).pay / total_comm_num) \ 1 '给维护宽度进行赋值
       go_back_width = (500 * myarr(i).go_back / total_comm_num) \ 1 '给回访宽度进行赋值
       Dim myrow As New Web.UI.WebControls.TableRow
       myrow.Width = Unit.Pixel(700)
       Dim j As Integer
       '以下循环是添加维护情况
       For j = 0 To pay_width
         If j = 0 Then '在第一列要写进用户的名称
           Dim mycell As New UI.WebControls.TableCell
           mycell.Text = myarr(i).name
           mycell.Width = WebControls.Unit.Pixel(60)
           Dim mycol As New Color
           mycell.BorderColor = mycol.DeepPink
           myrow.Cells.Add(mycell)
           Dim mycell2 As New UI.WebControls.TableCell
           myrow.Cells.Add(mycell2)
         Else '在第二列添加图片信息
           myspan = New HtmlControls.HtmlGenericControl
           myimage = New HtmlControls.HtmlImage
           myimage.Src = "Images/navbar.gif" '要显示的中间图片
           myspan.Controls.Add(myimage)
           myrow.Cells(1).Controls.Add(myspan)
         End If
       Next
       '以下循环是添加回访情况
       For j = 0 To go_back_width
         myspan = New HtmlControls.HtmlGenericControl
         myimage = New HtmlControls.HtmlImage
         myimage.Src = "Images/navbar2.gif" '要显示的中间图片
         myspan.Controls.Add(myimage)
         myrow.Cells(1).Controls.Add(myspan)
       Next
       mytable.Rows.Add(myrow)
     Next
     mytable.Width = Unit.Pixel(700)
   End Sub后记:以上代码在win2000+vs.net 中运行通过,由于是刚刚测试完成,代码有点乱(变量名称也是随意的,有点不能代表意思!)
