按照老师的指导  解决了cm4 组合框的列值显示

 

因为文本不是固定的间隔符，新增了t3这个控件来自定义输入间隔符，下述红色代码怎么能够实现  输入的间隔符号不同  都能够正确的导入文本数据呢？

当前代码运行效果：

vbtab没有办法作为一个字符放到文本框里的，建议作成勾选，如果勾选就使用vbtab，否则使用文本框内容作为分隔符

Dim jg As WinForm.CheckBox = e.Form.Controls("是否使用tab作为间隔符")
Dim bsbs As String
if jg.checked then
bsbs = vbtab
elseif e.Form.Controls("TextBox3").text > "" 如果指定了分隔符
bsbs = e.Form.Controls("TextBox3").text
else
bsbs = "|"  如果既不勾选，也不指定了分隔符，默认使用“|”
end if

这里开始正常导入，所有使用Split分隔行数据的地方直接Split(bsbs)即可

选择文件按钮代码：【运行也得不到对应的cm4正确值了】

Dim  dlg As  new  OpenFileDialog
dlg.Filter =  "文本文件|*.txt"
Dim t2 As WinForm.TextBox = e.Form.Controls("TextBox2")
Dim t3 As WinForm.TextBox = e.Form.Controls("TextBox3")
Dim cm4 As WinForm.ComboBox = e.Form.Controls("ComboBox4")
Dim jg As WinForm.CheckBox = e.Form.Controls("是否自定义间隔符")
Dim bsbs As String

Dim Multi As String
If  dlg.ShowDialog =  DialogResult.OK Then
    t2.text=dlg.FileName
    Dim  strs As  String =  FileSys.ReadAllText(t2.text, Encoding.Default)
    Dim Values11() As String =  strs.Replace(vbcr,"").split(vblf)
    Dim  rs As  String =  Values11(0)
   
    If jg.checked Then
        bsbs = vbtab
        Dim  cs1() As  String =  rs.Split(bsbs)
        cm4.ComboList=String.join("|",cs1)
    Else  If e.Form.Controls("TextBox3").text > "" '如果指定了分隔符
        bsbs = e.Form.Controls("TextBox3").text
        Dim  cs2() As  String =  rs.Split(bsbs)
        cm4.ComboList=String.join("|",cs2)
    Else
        bsbs = "|"  '如果既不勾选,也不指定了分隔符,默认使用"|"
        Dim  cs3() As  String =  rs.Split("|")
        output.Show(cs3(0))
        Multi = cs3(0)
        cm4.ComboList=Multi
    End If
End If

运行效果如下：
