问题描述
我尝试获取已安装的应用程序密钥的列表:
I try to get a list of installed application keys:
RegistryKey RegKeyUninstallList = Registry.LocalMachine;
string strUninstallList = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
string[] test = RegKeyUninstallList.OpenSubKey(strUninstallList).GetSubKeyNames();
我只能从以下位置获得钥匙:
I get only the Keys from:
但我还需要以下密钥:
我的程序应该能够在64Bit
和32Bit
机器上运行.
My program should be able to run on a 64Bit
and on a 32Bit
machine.
好的,我已经尝试过检查应用程序是否已安装在注册表中以及来自tHiNk_OuT_oF_bOx的解决方案.
edit: Ok I have tried Check if application is installed in registry and the solution from tHiNk_OuT_oF_bOx.
但没有任何方法可以解决问题!
But nothing has solved the Problem!
问题是我得到了与test和test2完全相同的列表:
The problem is i get exactly the same list for test and test2:
RegistryKey RegKeyUninstallList = Registry.LocalMachine;
string strUninstallList = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
string strUninstallList2 = @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall";
string[] test = RegKeyUninstallList.OpenSubKey(strUninstallList).GetSubKeyNames();
string[] test2 = RegKeyUninstallList.OpenSubKey(strUninstallList2).GetSubKeyNames();
推荐答案
解决方案是在注册表中搜索3个位置:
The solution is to search for 3 places in registry:
- SOFTWARE \ Microsoft \ Windows \ CurrentVersion \在CurrentUser中卸载
- SOFTWARE \ Microsoft \ Windows \ CurrentVersion \在LocalMachine中卸载
- SOFTWARE \ Wow6432Node \ Microsoft \ Windows \ CurrentVersion \在LocalMachine中卸载
下面的代码适合您的需求.
the code below suits you needs.
public static bool IsApplicationInstalled(string p_name)
{
string displayName;
RegistryKey key;
// search in: CurrentUser
key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall");
foreach (String keyName in key.GetSubKeyNames())
{
RegistryKey subkey = key.OpenSubKey(keyName);
displayName = subkey.GetValue("DisplayName") as string;
if (p_name.Equals(displayName, StringComparison.OrdinalIgnoreCase) == true)
{
return true;
}
}
// search in: LocalMachine_32
key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall");
foreach (String keyName in key.GetSubKeyNames())
{
RegistryKey subkey = key.OpenSubKey(keyName);
displayName = subkey.GetValue("DisplayName") as string;
if (p_name.Equals(displayName, StringComparison.OrdinalIgnoreCase) == true)
{
return true;
}
}
// 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 = subkey.GetValue("DisplayName") as string;
if (p_name.Equals(displayName, StringComparison.OrdinalIgnoreCase) == true)
{
return true;
}
}
// NOT FOUND
return false;
}
