C# と VB.NET の質問掲示板

こたえ示すのは簡単なんですけどね、
わかってないと応用が効きませんからねぇ...

--- Class1.vb ---
Public Class Class1
    Public a As Integer
    Sub New()
        a = 100
    End Sub
End Class

--- Form1.vb ---
Public Class Form1
    ' ボタン押されたら"100"って書く
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim x As New Class1 ' Class1オブジェクトxを作って
        TextBox1.Text = x.a.ToString() ' x.a を表示する
    End Sub
End Class

--- Calss1.vb ---
Public Class Class1
    Public filename As String
    Public elemname As String
    Sub New(ByVal f As String, ByVal e As String)
        filename = f
        elemname = e
    End Sub
End Class

--- Form1.vb ---
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim x As New Class1("FILE", "ELEM") ' ←こゆこと?
        TextBox1.Text = x.filename & "/" & x.elemname
    End Sub
End Class

> どのような原因が考えられますでしょうか？

勉強不足。
