vb.net - 使用 vb.net 从多个表单读取、写入数据的替代方式

Question

我正在处理一份工作申请。我们使用 excel 文件来创建报告。我对编码很生疏，真的没有遇到过这么大的要求。该应用程序的工作方式是有标准工具栏。当用户打开应用程序时，他会看到一个空白表单。他们必须首先创建一个新文件并将其保存到他们选择的文件夹中。我使用了流读取器/写入器，但问题是用户必须填写大量数据，所以我的代码很糟糕而且像怪物一样，我想知道有没有更简单的方法？

     ToolStripLabel1.Text = FileDataStorage.OpenFileTextBox1.Text
     If ToolStripLabel1.Text = ("C:\Temp\New QCA.qca") Then
        MsgBox("Must Save New file first ACCESS DENIED!")
        End If
     Dim FILE_NAME As String = FileDataStorage.OpenFileTextBox1.Text
    Try
        If System.IO.File.Exists(FILE_NAME) = True Then

            Dim objWriter As New System.IO.StreamWriter(FILE_NAME)

如果你的意思是让代码更优雅？您可以执行以下操作。

    ToolStripLabel1.Text = FileDataStorage.OpenFileTextBox1.Text

    If ToolStripLabel1.Text = ("C:\Temp\New QCA.qca") Then
        MsgBox("Must Save New file first ACCESS DENIED!")
    End If

    Dim FILE_NAME As String = FileDataStorage.OpenFileTextBox1.Text

    Try
        If System.IO.File.Exists(FILE_NAME) = True Then

            Dim objWriter As New System.IO.StreamWriter(FILE_NAME)
            For Each c As Control In Form.Controls
                If TypeOf c Is TextBox Or TypeOf c Is ComboBox Then
                    objWriter.WriteLine(c.Text)
                End If
            Next

            objWriter.Close()
            MsgBox("Data written to file")

         Else
            'Do Nothing
         End If
    Catch ex As Exception
         Throw
    End Try

与您已有的保持一致，类似的外部功能可能对您有用。它遍历传递给它的表单，然后找到某种类型的对象，然后将它们打印给您在那里创建的编写器。你必须让它与你已经拥有的东西一起工作，但这样的事情会节省很多行。

它所做的是获取表单上控件的数量，然后遍历每个控件以获取其类型。如果类型正确，那么它只是将其内容写入文件。

Private sub writeToFile(formFrom as Form)
    Dim controls As Control
    For Each controls In formFrom.Controls
        If TypeOf (controls) Is TextBox Then
            objWriter.WriteLine(formFrom.controls.text)
        elseif TypeOf (controls) is ComboBox then
            objWriter.WriteLine(formFrom.controls.text)
        End If
    Next
end sub
