我有2个列表框。 listbox1包含可变帐户名，

John
James
Matt

第二个列表框包含一个非变量脚本

Dear <account name>
Thank you for contacting us.

我将通过帐户名称循环。我有代码。但是如何在第3个列表框或文本框中获得输出，如下所示;

Dear John

Dear James

We will get back to you soon.

Dear Matt

我不确定您为什么使用ListBox作为静态文本，但此代码应该按照您希望的方式执行。我正在使用For Each遍历两个Listbox的Object Collections，将结果对象转换为字符串，然后将修改后的行添加到List（Of String），然后将其分配给TextBox的Lines属性。看看这是否适合你。

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim result As List(Of String) = New List(Of String)
    For Each item As Object In ListBox1.Items
        For Each line As Object In ListBox2.Items
            result.Add(CStr(line).Replace("<account name>", CStr(item))) 'Modify line and add to List
        Next
        result.Add("") 'Add seperator
        TextBox1.Lines = result.ToArray() 'Have to convert to String Array since that is what Lines is
    Next
End Sub
