MSI 安装程序选项 - 卸载应用程序 [英] MSI installer option- uninstalling an application
问题描述
如果我运行下面的代码,我很确定我应该获得应用程序的产品名称和 GUID(例如应用程序路径 | {xxx}).但我只得到了路径,没有显示 GUID.有人可以帮我吗?
If I run the code below I'm pretty sure I'm supposed to get the Product Name and GUID (ex. App Path | {xxx}) for the application. But I'm only getting the path and no GUID is shown. Can someone help me?
// search in: LocalMachine_64
key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall");
foreach (String keyName in key.GetSubKeyNames())
{
RegistryKey subkey = key.OpenSubKey(keyName);
displayName = Convert.ToString(subkey.GetValue("DisplayName"));
uninstlString = Convert.ToString(subkey.GetValue("UninstallString"));
if (p_name.Equals(displayName, StringComparison.OrdinalIgnoreCase))
{
Console.WriteLine(subkey.GetValue("UninstallString"));
//string prdctId = uninstlString.Substring((uninstlString.IndexOf("{")));
string prdctId = uninstlString.Substring(12);
uninstallProcess.StartInfo.FileName = "MsiExec.exe";
uninstallProcess.StartInfo.Arguments = " /x " + prdctId + " /quiet /norestart";
uninstallProcess.StartInfo.UseShellExecute = true;
uninstallProcess.Start();
uninstallProcess.WaitForExit();
break;
//Console.WriteLine(subkey.GetValue("UninstallString"));
}
}

推荐答案
我相信 UninstallString
值是通过 添加/删除程序
卸载应用程序时执行的值.正如您的控制台输出所示,它是可执行文件的路径.
I believe the UninstallString
value is what gets executed when uninstalling an application via Add/Remove Programs
. As your console output shows, it's the path to an executable.
您检索产品 ID 的方式...
The way you are retrieving the product ID...
string prdctId = uninstlString.Substring(12);
...因此,这是不正确的,因为您采用的是部分路径.您需要传递给 MsiExec.exe/x
的是产品代码,即注册表项名称本身,即....
...therefore, is incorrect because you are taking a partial path. What you need to pass to MsiExec.exe /x
is the product code, which is the registry key name itself, i.e....
string prdctId = keyName;
如果您从 Command Prompt
调用该命令行,我很确定大括号将需要在产品代码周围加上引号;我不确定在直接调用可执行文件时是否需要这样做,但它不会受到伤害...
If you were invoking that command line from Command Prompt
I'm pretty sure the curly brackets would necessitate putting quotes around the product code; I'm not sure if you'll need to do so when invoking the executable directly, but it can't hurt...
uninstallProcess.StartInfo.Arguments = " /x \"" + prdctId + "\" /quiet /norestart";
