    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim EachAccounts(4) As SturAccount

        EachAccounts(0).Name = "123"
        EachAccounts(0).Pw = "123"

        EachAccounts(1).Name = "fai"
        EachAccounts(1).Pw = "789"

        For i As Integer = 0 To 1
            List(i).Caption = 10
            For j As Integer = 0 To 1
                   'Error here. i dont know why.
              List(i).Accounts(j).Name = EachAccounts(j).Name
             List(i).Accounts(j).Pw = EachAccounts(j).Pw
            Next

推荐答案

如果您告诉我们错误是什么，它将有所帮助.但是，我会说Accounts(j)为null，需要先创建Accounts(j)，然后才能对其设置值.

If you told us what the error was, it would help. But, I''d say that Accounts(j) is null and needs to be created before you can set values on it.
