Question

我正在申请工作。我们使用excel文件来创建报告。我编码生锈，真的没有遇到如此大的要求。应用程序的工作方式是标准工具栏。当用户打开应用程序时，他会看到空白表单。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。我已经使用了流读取器/写入器，但问题是用户必须填写大量数据，因此我的代码很糟糕且像怪物一样，我想知道有更简单的方法吗？

     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

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

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

与您已有的一致，与此类似的外部功能可能对您有用。它遍历传递给它的表单，然后查找某种类型的对象，然后将它们打印到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，但是像这样的东西可以节省很多行。

它的作用是获取表单上的控件数量，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

使用vb.net从多个表单中读取，写入数据的替代方式
