如何回滚我的安装 [英] How can I Rollback My Installation

问题描述

我在C#& amp;中开发了应用程序我创建了它的设置& amp;部署.我想在我的应用程序设置中添加序列号.当该串行密钥正确时，请安装我的应用程序，否则回滚我的应用程序.我一直在通过用户界面(添加对话框)添加文本框.
请检查以下代码

公共重写void Install(System.Collections.IDictionary stateSaver)
{
base.Install(stateSaver);
试试
{
布尔值卸载= true;
字符串serialKey = Context.Parameters ["PathValue"];
如果(serialKey！="abcd")
{
卸载=假;
}
使用(var inst = new AssemblyInstaller(typeof(LicenseViewer.Program).Assembly，new string [] {}))
{
IDictionary状态= new Hashtable();
inst.UseNewContext = true;
试试
{
如果(卸载)
{
//inst.Uninstall(state);
inst.Rollback(state);
}
其他
{
inst.Install(状态);
inst.Commit(state);
}
}
赶上
{
试试
{
inst.Rollback(state);
}
catch(Exception e){MessageBox.Show(e.Message); }
投掷;
}
}

}
catch(ex ex例外)
{MessageBox.Show(ex.Message); }
}
当串行密钥在回滚之前的那个时间出错时，出现异常错误1001.找不到"namespace.installstate"".


我想检查文本框上的序列号(添加对话框).如果那次键不正确，那时候只显示消息无效键就不要转到下一页，如Microsoft Office安装程序.

I developed application in C# & I create its setup & deployment. I want to add serial key in setup of my application. When this serial key is right that time install my application otherwise rollback my application. I have been adding the textbox through User Interface (add dialog).
Please check the following code

public override void Install(System.Collections.IDictionary stateSaver)
{
base.Install(stateSaver);
try
{
Boolean uninstall = true;
string serialKey = Context.Parameters["PathValue"];
if (serialKey!= "abcd")
{
uninstall = false;
}
using (var inst = new AssemblyInstaller(typeof(LicenseViewer.Program).Assembly, new string[] { }))
{
IDictionary state = new Hashtable();
inst.UseNewContext = true;
try
{
if (uninstall)
{
// inst.Uninstall(state);
inst.Rollback(state);
}
else
{
inst.Install(state);
inst.Commit(state);
}
}
catch
{
try
{
inst.Rollback(state);
}
catch (Exception e) { MessageBox.Show(e.Message); }
throw;
}
}

}
catch (Exception ex)
{ MessageBox.Show(ex.Message); }
}
When the Serial key is wrong that time before rollback I got the exception "Error 1001. Could not find the ''namespace.installstate'' ".


I want to check serial key on textbox(add dialog).If key is wrong that time just show message invalid key not go to the next page like Microsoft Office setup.

推荐答案

在此代码触发之前，您尚未启动安装->

You have not started an Install before this code fires ->

if (uninstall)
  {
  //   inst.Uninstall(state);
  inst.Rollback(state);
}

因此，您会收到错误消息.

Thus you get an error.

当您尝试通过双击Setup.msi文件在Windows Vista或2008上安装PR-Tracker时，将发生这些错误.改为运行Setup.exe.

These errors occur when you try to install PR-Tracker on Windows Vista or 2008 by double-clicking the Setup.msi file. Run Setup.exe instead.
