我目前有一个巨大的IF语句,并希望尽量减少它。在VB中实现标签名称中的变量?
我有一个数据网格,我从SQL查询填充,然后从这个数据网格我将值传递到单独的标签。
我能够创建一个For Each循环,在该循环中,我循环查看变量,直到计数器达到7.但是,当我需要将标签名称值增加1时,会出现问题。每次,所以基本上我需要在标签名称中添加一个计数器变量。
,我需要最小化的代码是:
result73 = DataGridView1.Rows(0).Cells(0).Value.ToString
result74 = DataGridView1.Rows(0).Cells(1).Value.ToString
result75 = DataGridView1.Rows(1).Cells(0).Value.ToString
result76 = DataGridView1.Rows(1).Cells(1).Value.ToString
result77 = DataGridView1.Rows(2).Cells(0).Value.ToString
result78 = DataGridView1.Rows(2).Cells(1).Value.ToString
result79 = DataGridView1.Rows(3).Cells(0).Value.ToString
result80 = DataGridView1.Rows(3).Cells(1).Value.ToString
result81 = DataGridView1.Rows(4).Cells(0).Value.ToString
result82 = DataGridView1.Rows(4).Cells(1).Value.ToString
result83 = DataGridView1.Rows(5).Cells(0).Value.ToString
result84 = DataGridView1.Rows(5).Cells(1).Value.ToString
result85 = DataGridView1.Rows(6).Cells(0).Value.ToString
result86 = DataGridView1.Rows(6).Cells(1).Value.ToString
result87 = DataGridView1.Rows(7).Cells(0).Value.ToString
result88 = DataGridView1.Rows(7).Cells(1).Value.ToString
If result73 = "Monday" Then
DaySalesLbl1.Text = result74
ElseIf result73 = "Tuesday" Then
DaySalesLbl2.Text = result74
ElseIf result73 = "Wednesday" Then
DaySalesLbl3.Text = result74
ElseIf result73 = "Thursday" Then
DaySalesLbl4.Text = result74
ElseIf result73 = "Friday" Then
DaySalesLbl5.Text = result74
ElseIf result73 = "Saturday" Then
DaySalesLbl6.Text = result74
ElseIf result73 = "Sunday" Then
DaySalesLbl7.Text = result74
End If
这个if语句继续针对以上声明的每个变量。我创建
的循环看起来是这样的:
Dim cou As Integer
Dim n As Integer
cou = 0
n = 1
Do Until result74 <> ""
If result73 = cou Then
DaySalesLbl +n = result74
End If
cou = cou + 1
n = n + 1
Loop
但部分DaySalesLbl +n = result74
带来了一个错误,因为它会查找生成的方法。
这太好了,谢谢你的帮助。有效 :) –
