在开始之前,请注意,我read almost所有相关问题都在此处,并且没有找到解决方案。因此,问题的目标与以前的问题相同:
如何正确删除应用程序使用WiX工具时正在创建的临时文件夹和misc文件?
到目前为止,我想出了以下方法:
使用 CustomAction (例如,在C#中编写),它将删除所有文件和文件夹(这很有用,但这种解决方法在我看来无效,因为没有支持从MSI方面回滚。)
使用 WixUtilExtension 中的 util:RemoveFolderEx 标记。我无法完成这项工作。
使用 CustomAction (再次在C#中编写)将填充MSI数据库的表格(目录和删除文件)在UnInstall发生之前。这将强制MSI以自己的方式正确地卸载所有枚举的文件和文件夹(理论上它应该这样做)通过 RemoveFiles 默认操作。
我专注于第三种方式并在此向您提供一些帮助。
关于应用程序布局的几点说明
我构建的MSI与 ProgramFiles ,快捷方式,注册表以及所有这些功能相得益彰。但是在安装过程中,我将一些配置文件放入C:\ProgramData\MyApp\
文件夹(它们也被删除,没有任何问题)。
但是当应用程序工作时,它会在C:\ProgramData\MyApp\
中生成其他文件和目录,用于在新版本可用时更新应用程序。假设用户在更新过程中关闭应用程序并想要卸载应用程序。以下是我们目前在C:\ProgramData\MyApp
文件夹中的内容:
C:\ ProgramData \ MyApp的\
C:\ ProgramData \ MyApp的\ TEMP \
C:\ ProgramData \ MyApp的\ TEMP \ tool.exe
C:\ ProgramData \ MyApp的\ TEMP \ somelib.dll
C:\ ProgramData \ MyApp的\温度\< UniqueFolderNameBasedOnGUID> \ someliba.dll
C:\ ProgramData \ MyApp \ Temp \< UniqueFolderNameBasedOnGUID< \ somelibb.dll
在卸载过程结束时,我想看到没有C:\ProgramData\MyApp\
文件夹。如果没有创建临时目录/文件,我可以看到这个。
请注意,我不知道放在C:\ProgramData\MyApp\Temp\
文件夹中的文件夹和文件的名称,因为最终文件夹名称是使用GUID自动生成的。
让我专注于项目最重要的部分,并向您展示我到目前为止完成任务所做的工作(请记住,我选择了第三种方式:通过 CustomAction ) :
Main MyApp.wxs file
<Product Id=...>
...
<!-- Defines a DLL contains the RemoveUpdatesAction function -->
<Binary Id="RemoveUpdatesAction.CA.dll" src="RemoveUpdatesAction.CA.dll" />
<CustomAction Id="RemoveUpdatesAction"
Return="check"
Execute="immediate"
BinaryKey="RemoveUpdatesAction.CA.dll"
DllEntry="RemoveUpdatesAction" />
...
<InstallExecuteSequence>
<!-- Perform custom CleanUp only on 'UnInstall' action - see condition -->
<Custom Action='RemoveUpdatesAction' Before='RemoveFiles'>
(NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL")
</Custom>
</InstallExecuteSequence>
...
</Product>
稍后在文件中,我为 ProgramData 目录定义 Folder Layout
:
<Fragment>
<Directory Id="TARGETDIR" Name="SourceDir">
....
<!-- ...\Program Files\MyApp\ -->
<Directory Id="ProgramFilesFolder">
<Directory Id="APPINSTALLFOLDER" Name="MyApp" />
</Directory>
....
<!-- This is it! ...\ProgramData\MyApp\ -->
<Directory Id="CommonAppDataFolder">
<Directory Id="SETTINGSINSTALLFOLDER" Name="MyApp" />
</Directory>
....
</Directory>
</Fragment>
... a lot of different stuff here ...
<Fragment>
<Component Id="AddConfigurationFilesFolder" ...>
...
<!-- This component just serves as a bound point - see below -->
...
</Fragment>
到目前为止一切顺利。
现在, RemoveUpdatesAction.cs file
包含自定义操作:
public class CustomActions
{
[CustomAction]
public static ActionResult RemoveUpdatesAction(Session session)
{
try
{
// Provide unique IDs
int indexFile = 1;
int indexDir = 1;
// Begin work
session.Log("Begin RemoveUpdatesAction");
// Bind to the component that for sure will be uninstalled during UnInstall action
// You can see this component mentioned above
const string componentId = "AddConfigurationFilesFolder";
// Get '..\{ProgramData}\MyApp' folder
// This property (SETTINGSINSTALLFOLDER) is mentioned too
string appDataFolder = session["SETTINGSINSTALLFOLDER"];
// Populate RemoveFile table in MSI database with all files
// created in '..\{ProgramData}\MyApp\*.*' folder - pls see notes at the beginning
if (!Directory.Exists(appDataFolder))
{
session.Log("End RemoveUpdatesAction");
return ActionResult.Success;
}
foreach (var directory in Directory.GetDirectories(appDataFolder, "*", SearchOption.AllDirectories))
{
session.Log("Processing Subdirectory {0}", directory);
foreach (var file in Directory.EnumerateFiles(directory))
{
session.Log("Processing file {0}", file);
string keyFile = string.Format("CLEANFILE_{0}", indexFile);
// Set values for columns in RemoveFile table:
// {1}: FileKey => just unique ID for the row
// {2}: Component_ => reference to a component existed in Component table
// In our case it is already mentioned 'AddConfigurationFilesFolder'
// {3}: FileName => localizable name of the file to be removed (with ext.)
// {4}: DirProperty => reference to a full dir path
// {5}: InstallMode => 3 means remove on Install/Remove stage
var fieldsForFiles = new object[] { keyFile, componentId, Path.GetFileName(file), directory, 3 };
// The following files will be processed:
// 1. '..\ProgramData\MyApp\Temp\tool.exe'
// 2. '..\ProgramData\MyApp\Temp\somelib.dll'
// 3. '..\ProgramData\MyApp\Temp\<UniqueFolderNameBasedOnGUID>\someliba.dll'
// 4. '..\ProgramData\MyApp\Temp\<UniqueFolderNameBasedOnGUID>\somelibb.dll'
InsertRecord(session, "RemoveFile", fieldsForFiles);
indexFile++;
}
string keyDir = string.Format("CLEANDIR_{0}", indexDir);
// Empty quotes mean we we want to delete the folder itself
var fieldsForDir = new object[] { keyDir, componentId, "", directory, 3 };
// The following paths will be processed:
// 1. '..\ProgramData\MyApp\Temp\'
// 2. '..\ProgramData\MyApp\Temp\<UniqueFolderNameBasedOnGUID>\'
InsertRecord(session, "RemoveFile", fieldsForDir);
indexDir++;
}
session.Log("End RemoveUpdatesAction");
return ActionResult.Success;
}
catch (Exception exception)
{
session.Log("RemoveUpdatesAction EXCEPTION:" + exception.Message);
return ActionResult.Failure;
}
}
// Took completely from another SO question, but is accoring to MSDN docs
private static void InsertRecord(Session session, string tableName, Object[] objects)
{
Database db = session.Database;
string sqlInsertSring = db.Tables[tableName].SqlInsertString + " TEMPORARY";
View view = db.OpenView(sqlInsertSring);
view.Execute(new Record(objects));
view.Close();
}
}
注意:我从here获取的条件((NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL")
)。
这几乎就是我所做的全部,在安装/卸载循环之后,我在msi日志文件和RemoveFile表中看到(通过枚举记录)确实插入了所有这些条目。
但..\ProgramData\MyApp\Temp\...
中的文件和文件夹仍然无论我做什么。
任何人都可以澄清我做错了什么吗?
我认为问题可能在于如何在Custom Action类中定义 DirProperty 。我在那里放了一个目录路径,但我知道(使用Orca)在目录表中没有我通过Directory.GetDirectories
发现的临时文件夹的记录。
所以 RemoveFile 表正在填充对目录表有无效引用的记录(是吗?)。我尝试手动将这些发现的文件夹添加到目录表中但失败了 - 每次我尝试引用目录表时都会出现异常。在MSI中填充目录表的正确方法是什么?根本填充目录表是否有意义?
例如,如果我需要放置以下路径:
..\ProgramData\MyApp\Temp\
..\ProgramData\MyApp\Temp\<UniqueFolderNameBasedOnGUID>\
我该怎么做?
无论如何,请提出建议 - 任何建议,提示或意见将不胜感激!
非常感谢!

正如您所看到的,我有 2727 错误代码。 That means对于以下文件夹,目录表中没有记录:
C:\ ProgramData \ MyApp的\温度
C:\ ProgramData \ MyApp的\ TEMP \ 48574917-4351-4d4c-a36c-381f3ceb2e56
那么,也许我的建议是正确的?
所提到的标签,MSI表等引用:
Creating WiX Custom Actions in C# and Passing Parameters
MSI DB's RemoveFile table description
MSI DB's Directory table description
RemoveFiles Action
WiX CustomAction Element
答案 0 :(得分:0)
据我所知,你没有正确填充RemoveFile表。如果你记录了那个确切的SQL插入字符串,看看它到底有什么用,这会有所帮助。我认为你得到错误2727因为你插入的第四件事应该是一个引用MSI文件中的目录表的目录属性。它不是字面上的目录名 - 它应该是MSI文件目录表中的一个键 - 据我所知,它是一个实际目录,而不是Directory表中的值。
