如何获取应用程序的 AppData VirtualStore 路径？

Question

我想在VirtualStore 中获取应用程序的路径。

例如，我需要的文件在这个目录下（我从注册表中获取这个路径）

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

我怎样才能得到这个路径？

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

更新：

此路径不在我的应用程序中。

我问只知道程序文件中的winodows用户名和路径时如何获取应用程序数据中的路径

Answer 1

假设Example App 是运行代码的应用程序，则使用检索第一个目录

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

第二个乍一看并不像一个固定的位置，但为此您可以尝试Application 和Environment 类。尝试类似

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

我希望这会有所帮助。

过去，一些应用程序读写ini配置文件在当前的安全状态下是不可取的，微软windows操作系统（os）是相当满意的。在 Windows 7、8 和 10 中，操作系统会保护这些文件夹，将新版本存储在用户配置文件 VirtualStore 下。

下面的 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'不存在，检查原始位置（“C：\ Program Files（x86）\ Example App”）。 CheckFile() 将返回文件的完整文件路径。

FullFilePath = CheckFile("C:\Program Files (x86)\Example App", "data.ini"));

它也适用于您的旧代码可能会尝试弄乱的其他文件夹（例如“C:\Windows”）。

下面是 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;
    }
}

下面是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
