不保留自定义类中属性值的更改

问题描述

我创建了此函数，以从自定义类的属性值中删除vbCrLf:(vTransaction)

I created this function to remove vbCrLf from the values of properties in a Custom Class:(vTransaction)

Public Function ValidateTransaction(ByRef vTransaction)            Dim property1 As String
        Dim value1 As String

        For Each p As System.Reflection.PropertyInfo In vTransaction.GetType().GetProperties()
            If p.CanRead Then
                property1 = p.Name ''// FOR TESTING to identify Property Name
                value1 = p.GetValue(vTransaction, Nothing)
                If (TypeOf value1 Is String) Then
                    If value1 <> " " And value1 <> "" Then
                        ''MsgBox("Before .Replace:" & vbNewLine & value1.ToString) ''// FOR TESTING.
                        value1 = value1.ToString.Replace(vbCrLf, " ")
                        ''MsgBox("After .Replace:" & vbNewLine & value1.ToString) ''// FOR TESTING.
                    End If
                End If
            End If
        Next

        Return vTransaction

    End Function

在整个测试中，我可以验证vbCrLf是否已按预期替换为空格.当我重新检查vTransaction时，更改尚未保留，并且vbCrlf仍然存在.
我需要做些什么来保留对vTransaction中的值所做的更改.

Throughout testing I can verify that vbCrLf is being replaced with a space as expected. When I re-examine vTransaction the changes have not been retained and the vbCrlf''s are still there.
What do I need to do to retain the changes being made to values in vTransaction.

推荐答案

Public Function ValidateTransaction(ByRef vTransaction)
    Dim property1 As Object
    Dim value1 As Object

    For Each p As System.Reflection.PropertyInfo In vTransaction.GetType().GetProperties()
        If p.CanRead Then
            property1 = p.Name '// FOR TESTING to identify Property Name
            value1 = p.GetValue(vTransaction, Nothing)
            If (TypeOf value1 Is String) Then
                If value1 <> " " And value1 <> "" Then
                    'MsgBox("Before .Replace:" & vbNewLine & value1.ToString) '// FOR TESTING.
             p.SetValue(sTransaction, value1 = value1.ToString.Replace(vbCrLf, " "), Nothing)
                    'MsgBox("After .Replace:" & vbNewLine & value1.ToString) '// FOR TESTING.
                End If
            End If
        End If
    Next

    Return sTransaction

End Function
