如何遍历每个按钮以检查它们是否已启用？

Question

我想做一个For Each循环,我可以检查每个按钮是启用还是禁用.如果启用该按钮,则必须获取每个按钮的标签中的值.我有26个按钮,每个按钮包含不同的值(现金奖励).*重要提示:此代码需要在按钮下方,所以每按六次按钮就会检查按钮.

伪代码:

btncase1.tag = 5
Begin while statement to go through each button
   Check each button to see if it is enabled
   If button is enabled then obtain values
Next

我有实际代码,但它对我没有任何意义:

Public Class Form1
Dim button As Button
Dim totalremcases As Integer
Dim btncase As New Control
Dim btncollection As New Microsoft.VisualBasic.Collection()

Private Sub btncase1_Click()
For Each button As Button In btncollection
    If btncase.Enabled Then
        totalremcases = totalremcases + CInt(btncase.Tag)
    End If
Next

您可以尝试使用此方法解决它

  Public Sub getallcontrolls(controls As System.Web.UI.ControlCollection)
    Dim myAL As New ArrayList()
    For Each ctrl As Control In controls
        If TypeOf ctrl Is Button Then
            If ctrl.Enabled = True Then
                Dim tag As String = ctrl.Tag.ToString()
                myAL.Add(tag)
            End If

        End If
    Next
End Sub
