如何获取应用程序的AppData VirtualStore路径？

Question

我想获取在VirtualStore中应用程序的路径。

例如，我需要的文件在这个目录中（我从注册表中获取这个路径）：

C:\Program Files (x86)\Example App\data.ini

如何获取这个路径？

C:\Users\User388\AppData\Local\VirtualStore\Program Files (x86)\Example App\data.ini

更新： 这些路径不是我的应用程序。

我想知道如何在只知道Windows用户名和程序文件路径的情况下获取应用程序数据路径。

你可以像文件仍在 C:\Program Files (x86)\Example App\data.ini 中一样访问它。Windows文件虚拟化将为您完成此工作。有关文件虚拟化的更多详细信息，请参见http://www.codeproject.com/Articles/66275/Windows-Vista-File-and-Registry-Virtualization。 - Harvey Kwok

Answer 1

假设正在运行该代码的应用程序是Example App，则第一个目录是使用以下方式检索的：

string strFilePath = Path.Combine(Application.ExecutablePath, "Data.ini");

第二个位置乍一看不像是一个固定位置，但你可以尝试使用Application和Environment类进行实验。可以尝试类似于以下的操作：

string strFilePath = Path.Combine(Application.UserAppDataPath, "Data.ini");

希望这可以帮到你。

过去，一些应用程序在当前安全状态下不建议的位置读取和写入ini配置文件，而微软Windows操作系统（OS）非常满意。在Windows 7、8和10中，OS保护这些文件夹，将新版本存储在用户配置文件VirtualStore下。

以下C#和VB.net代码检查文件是否存在于VirtualStore路径中（即“C:\Users\\AppData\Local\VirtualStore\Program Files (x86)\Example App”），如果不存在，则在原始位置（“C:\Program Files (x86)\Example App”）中进行检查。CheckFile()将返回文件的完整路径。

它还可以处理其他文件夹（如“C:\Windows”），以防您的旧代码可能会出错。

以下是C#代码：

public void Main()
{
    string Path = "";
    string File = "data.ini";
    string FullFilePath = "";

    // we can get
    Path = System.Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
    //Path = "C:\Program Files (x86)\Example App"
    FullFilePath = CheckFile(Path, File);

    Interaction.MsgBox("FullFilePath: " + FullFilePath, MsgBoxStyle.Information + MsgBoxStyle.OkOnly, "Example Debug");
}

/// <summary>
/// CheckFile() - Check the String with Path and Filename. Make sure path is padded to the right with a \
/// </summary>
/// <param name="FilePath">Path of the file</param>
/// <param name="FileName">File name</param>
/// <returns>String with Path and Filename</returns>
/// <remarks>
/// Support the file search in user VirtualStore first and original path later.
/// </remarks>
public string CheckFile(string FilePath, string FileName)
{
    string OriginalPath = "";
    string VirtualStorePath = "";

    // Make sure path is padded to the right with a \
    if (FilePath.EndsWith("\\")) {
        OriginalPath = FilePath;
    } else {
        OriginalPath = FilePath + "\\";
    }

    VirtualStorePath = System.Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\\VirtualStore\\" + OriginalPath.Substring(3);
    //MsgBox("VirtualStorePath: " & VirtualStorePath & vbNewLine & "OriginalPath: " & OriginalPath,
    //       MsgBoxStyle.Information + MsgBoxStyle.OkOnly, "AIMS Debug")

    // return first VirtualStorePath if the file exists in user VirtualStore
    if (IO.File.Exists(VirtualStorePath + FileName)) {
        FilePath = VirtualStorePath;
        return VirtualStorePath + FileName;
    }
    if (IO.File.Exists(OriginalPath + FileName)) {
        return OriginalPath + FileName;
    } else {
        Interaction.MsgBox("No file in CheckFile(FilePath: " + FilePath + Constants.vbNewLine + "FileName: " + FileName + ")", MsgBoxStyle.Information + MsgBoxStyle.OkOnly, "Example Debug");
        // we don't have this file
        return OriginalPath + FileName;
    }
}

以下是VB.net代码：

Sub Main()
        Dim Path As String = ""
        Dim File As String = "data.ini"
        Dim FullFilePath As String = ""

        ' we can get
        Path = System.Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData)
        'Path = "C:\Program Files (x86)\Example App"
        FullFilePath = CheckFile(Path, File)

        MsgBox("FullFilePath: " & FullFilePath, MsgBoxStyle.Information + MsgBoxStyle.OkOnly, "Example Debug")
    End Sub

    ''' <summary>
    ''' CheckFile() - Check the String with Path and Filename. Make sure path is padded to the right with a \
    ''' </summary>
    ''' <param name="FilePath">Path of the file</param>
    ''' <param name="FileName">File name</param>
    ''' <returns>String with Path and Filename</returns>
    ''' <remarks>
    ''' Support the file search in user VirtualStore first and original path later.
    ''' </remarks>
    Function CheckFile(ByVal FilePath As String, ByVal FileName As String) As String
        Dim OriginalPath As String = ""
        Dim VirtualStorePath As String = ""

        ' Make sure path is padded to the right with a \
        If FilePath.EndsWith("\") Then
            OriginalPath = FilePath
        Else
            OriginalPath = FilePath & "\"
        End If

        VirtualStorePath = System.Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) & "\VirtualStore\" & OriginalPath.Substring(3)
        'MsgBox("VirtualStorePath: " & VirtualStorePath & vbNewLine & "OriginalPath: " & OriginalPath,
        '       MsgBoxStyle.Information + MsgBoxStyle.OkOnly, "AIMS Debug")

        ' return first VirtualStorePath if the file exists in user VirtualStore
        If IO.File.Exists(VirtualStorePath & FileName) Then
            FilePath = VirtualStorePath
            Return VirtualStorePath & FileName
        End If
        If IO.File.Exists(OriginalPath & FileName) Then
            Return OriginalPath & FileName
        Else
            MsgBox("No file in CheckFile(FilePath: " & FilePath & vbNewLine & "FileName: " & FileName & ")",
                   MsgBoxStyle.Information + MsgBoxStyle.OkOnly, "Example Debug")
            ' we don't have this file
            Return OriginalPath & FileName
        End If
    End Function
