提问by Nemo
As suggested here, I need to iterate through entries in
正如这里所建议的，我需要遍历中的条目
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
to find out the installed path of my application. How to iterate so that I can find out the InstallLocationvalue given the DisplayName. How to do it efficiently in C#.

Below is code to achieve your goal:
以下是实现目标的代码：
class Program
{
static void Main(string[] args)
{
RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Uninstall");
foreach (var v in key.GetSubKeyNames())
{
Console.WriteLine(v);
RegistryKey productKey = key.OpenSubKey(v);
if (productKey != null)
{
foreach (var value in productKey.GetValueNames())
{
Console.WriteLine("\tValue:" + value);
// Check for the publisher to ensure it's our product
string keyValue = Convert.ToString(productKey.GetValue("Publisher"));
if (!keyValue.Equals("MyPublisherCompanyName", StringComparison.OrdinalIgnoreCase))
continue;
string productName = Convert.ToString(productKey.GetValue("DisplayName"));
if (!productName.Equals("MyProductName", StringComparison.OrdinalIgnoreCase))
return;
string uninstallPath = Convert.ToString(productKey.GetValue("InstallSource"));
// Do something with this valuable information
}
}
}
Console.ReadLine();
}
}
Edit:See this method for a more comprehensive way to find an Applications Install Path, it demonstrates the usingdisposing as suggested in the comments.

using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"Whater\The\Key"))
{
if (key != null)
{
foreach (string ValueOfName in key.GetValueNames())
{
try
{
bool Value = bool.Parse((string)key.GetValue(ValueOfName));
}
catch (Exception ex) {}
}
}
}
With a bool cast :D - so the string is expected to be True or False.
使用 bool cast :D - 所以字符串应该是 True 或 False。
For the user registry hive use Registry.CurrentUserinstead of Registry.LocalMachine
对于用户注册表配置单元使用Registry.CurrentUser而不是 Registry.LocalMachine
