卸载前获取应用程序的安装路径 [英] get the installation path of the application before uninstall

问题描述

大家好，
卸载之前如何获取应用程序的安装路径?我的意思是用户选择卸载应用程序的时间.

我已经创建了一个安装程序类，并在BeforeUninstall事件中使用以下代码来查找应用程序路径，但它在Windows驱动器(C:\ Windows \ ...)中返回错误的路径:

Hi all,
How can i get the installation path of my application before uninstall it? I mean the time that the user select to uninstall the application.

I have create an Installer Class and use the following code in BeforeUninstall event to find application path but it returns a wrong path in Windows drive(C:\Windows\...):

using Microsoft.Win32;

RegistryKey key = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Installer\Assemblies");
string regfilepath="";
if (key!=null)       // Make sure there are Assemblies
{
    foreach(string Keyname in key.GetSubKeyNames())
    {
        if (Keyname.IndexOf("YOUR_EXE_FILE.EXE")>0)
        {
    regfilepath=Keyname;
    break;
        }
   }
}
string fullpath="";
for (int a=0;a<regfilepath.Length;a++)
{
  if (regfilepath.IndexOf("|",a,1)>0)
   fullpath+="\\";
 else
  fullpath+=regfilepath.Substring(a,1);
}
