Question

我想将员工ID增加为E1，E2，E3等等如何做到这一点.... Val（TextBox19.Text）+ 1我这样做是为了增加1,2,3但是如何追加E在VB.net中每个数字的开头

Answer 1

我通过偷偷摸摸地做到这一点...... 但我认为这就是你正在寻找的东西。每次点击按钮，你都会得到E＆＃34; E＆＃34; +递增的数字。

对这个想法很感兴趣，我最终坚持了5个小时:)（没什么好做的）

Public Class Form1

'When Form1 loads.
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    'We hide TextBox1
    TextBox1.Hide()

End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

    'This will increment +1 in the hidden textbox.
    Dim i As Integer

    i = Val(TextBox1.Text) + 1

    TextBox1.Text = i

    'We dim the result of the hidden textbox as string, then finally connect "Add" with "Result"
    Dim Add As String
    Add = "E"

    Dim Result As String
    Result = TextBox1.Text

    TextBox2.Text = Add & Result

End Sub

End Class
