更改路径保存mysettings - VB.NET 2008

Question

我使用mysettings保存的用户设置。

此配置文件被保存在这个路径：

  

C：\ Documents和   设置\ \ [本地   设置]应用   数据\\ \

有可能改变这个路径？例如，在我来说，我保存应用程序数据“ProgramData”文件夹（Vista和W7），我想保存在同一文件夹这个配置文件。是可能的？

在预先感谢

这是我的经验，如果你说你将Win XP的转移设置Vista或W7，这是不可能修复的文件夹路径。

然而，在一台PC，您可以通过标志使用SN工具修复的文件夹路径的ApplicationData \应用程序名称\ anUgLycOde \您的.exe文件。 （该uglu代码将每次重建和符号将防止这种变化）。

不过，如果你认为做一个交叉win版，我建议你不要用我的设置，但使用XML序列化。创建一个类通过使用XML序列化和反序列化来定义您的设置，加载和保存它。你可以把我的文件或* .EXE的文件夹。

下面是示例：

Imports System.Xml.Serialization

<XmlRoot("FTPSender")> _
Public Class FTPSenderConfig

    ' default file path relative to the current .exe file path.
    Const fDefaultCFGFile As String = "FTPSender.cfg"
    Public Shared ReadOnly Property DefaultFilePath() As String
        Get
            Return IO.Path.GetDirectoryName(System.Windows.Forms.Application.ExecutablePath) & "\" & fDefaultCFGFile
        End Get
    End Property

    Public Shared Function Load(Optional ByVal FilePath As String = Nothing) As FTPSenderConfig
        If FilePath Is Nothing Then FilePath = DefaultFilePath()
        If Not IO.File.Exists(FilePath) Then Return New FTPSenderConfig() ' load default settings
        Using sr As New IO.StreamReader(FilePath)
            Try
                Dim x As New XmlSerializer(GetType(FTPSenderConfig))
                Load = CType(x.Deserialize(sr), FTPSenderConfig)
                'MyLog.WriteLog("FTPSender settings loaded.")
            Finally
                If sr IsNot Nothing Then
                    sr.Close()
                    sr.Dispose()
                End If
            End Try
        End Using
    End Function

    Public Shared Sub Save(ByVal FTPSenderConfig As FTPSenderConfig, Optional ByVal FilePath As String = Nothing)
        If FilePath Is Nothing Then FilePath = DefaultFilePath()
        If FTPSenderConfig Is Nothing Then Return
        Using sw As New IO.StreamWriter(FilePath)
            Try
                Dim x As New XmlSerializer(FTPSenderConfig.GetType())
                x.Serialize(sw, FTPSenderConfig)
                'MyLog.WriteLog("FTPSender settings saved.")
            Finally
                If sw IsNot Nothing Then
                    sw.Close()
                    sw.Dispose()
                End If
            End Try
        End Using
    End Sub

        Dim fHost As String = "127.0.0.1"
        <XmlElement("Host")> _
        Public Property Host() As String
            Get
                Return fHost
            End Get
            Set(ByVal value As String)
                fHost = value
            End Set
        End Property

        Dim fUser As String = "guess"
        <XmlElement("User")> _
        Public Property User() As String
            Get
                Return fUser
            End Get
            Set(ByVal value As String)
                fUser = value
            End Set
        End Property

        Dim fPassEncrypted As String = EncDec.Encrypt("guess")
        <XmlElement("PassEncrypted")> _
        Public Property PassEncrypted() As String
            Get
                Return fPassEncrypted
            End Get
            Set(ByVal value As String)
                fPassEncrypted = value
            End Set
        End Property

        <XmlIgnore()> _
        Public Property Pass() As String
            Get
                Return EncDec.Decrypt(fPassEncrypted)
            End Get
            Set(ByVal value As String)
                fPassEncrypted = EncDec.Encrypt(value)
            End Set
        End Property

        Dim fTransferMode As String = MyFTPClient.TransferModeEnum.Passive.ToString()
        <XmlElement("TransferMode")> _
        Public Property TransferMode() As MyFTPClient.TransferModeEnum
            Get
                Return [Enum].Parse(GetType(MyFTPClient.TransferModeEnum), fTransferMode)
            End Get
            Set(ByVal value As MyFTPClient.TransferModeEnum)
                fTransferMode = value.ToString()
            End Set
        End Property

End Class

要使用它简单地为：

Dim cfg As FTPSenderConfig

cfg = FTPSenderConfig.Load() ' In Form_Load

Dim h as String = cfg.Host
cfg.Host = h

FTPSenderConfig.Save(cfg) ' In Form_FormClosed
