Hello All,

I am facing problem in Windows Installer Rollback functionality using C#.net
2.0. I have created an installer class and it launches custom action
[installer type] to create database and take user inputs for application
settings, If user wants to rollback I use InstallerException with custom
message, but if I do so then in the install directory some temp files and
CreateDatabase.InstallState [CreateDatabase is the name of my application
which is launched through custom action] file are not removed and these are
supposed to be removed.
In the mentioned scenario I want to rollback in such a way that system should
be restored to its initial state as it is requirement for Windows 7 logo
certification. Any help in this regard will be highly appreciated.
Regards.

推荐答案

如果安装出现任何问题，或者发生了卸载，则需要撤消所做的任何更改.在Rollback()和Uninstall()中，您可以访问保存在stateServer中的值. Rollback()和Uninstall()都调用我自己的新方法RemoveCustomAdditions().这将获取保存的路径字符串；如果存在，则文件将被删除.

公共重写void Rollback(IDictionary stateSaver)
{
base.Rollback(stateSaver);
RemoveCustomAdditions(stateSaver);
}
公共重写void Uninstall(IDictionary stateSaver)
{
base.Uninstall(stateSaver);
RemoveCustomAdditions(stateSaver);
}
private void RemoveCustomAdditions(IDictionary stateSaver)
{
试试
{
字符串BeginLinkPath = stateSaver ["BeginLinkPath"]作为字符串；
如果(！String.IsNullOrEmpty(BeginLinkPath))
File.Delete(BeginLinkPath);

字符串InfoLinkPath = stateSaver ["InfoLinkPath"]作为字符串；
如果(！String.IsNullOrEmpty(InfoLinkPath))
File.Delete(InfoLinkPath);
}
catch(Exception){}
}

此代码可以为您提供帮助. :)

If anything goes wrong with the install, or an uninstall occurs, you need to undo any changes you have made. In Rollback() and Uninstall() you have access to the values that were saved in stateServer. Both Rollback() and Uninstall() call my own new method RemoveCustomAdditions(). This gets the saved path strings; if they are present then the file is deleted.

public override void Rollback(IDictionary stateSaver)
{
base.Rollback(stateSaver);
RemoveCustomAdditions(stateSaver);
}
public override void Uninstall(IDictionary stateSaver)
{
base.Uninstall(stateSaver);
RemoveCustomAdditions(stateSaver);
}
private void RemoveCustomAdditions(IDictionary stateSaver)
{
try
{
string BeginLinkPath = stateSaver["BeginLinkPath"] as string;
if (!String.IsNullOrEmpty(BeginLinkPath))
File.Delete(BeginLinkPath);

string InfoLinkPath = stateSaver["InfoLinkPath"] as string;
if (!String.IsNullOrEmpty(InfoLinkPath))
File.Delete(InfoLinkPath);
}
catch (Exception ) { }
}

This code may Help you. :)
