How to uninstall MSI using its Product Code in c#

I know We can uninstall a windows application using its MSI by passing command arguments as follows,

Process p = new Process(); 
p.StartInfo.FileName = "msiexec.exe"; 
p.StartInfo.Arguments = "/x \"C:\\MyApplication.msi\"/qn"; 
p.Start(); 

But what i want to know is how can we uninstall the application without using MSI ? In the above scenario I should have the MSI in the specific location to uninstall this application, If i could unstaill using product code then I dont need to have the MSI in the target machine.

How do I manually uninstall MSI?

Uninstalling an MSI from the command line using the msiexec.exe. If you have access to the original MSI, then you can use the msiexec /x <path to the MSI file> command to uninstall your application. Windows Installer technology uses msiexec.exe for both the installation and uninstallation of MSI packages.

According to MSDN, You can uninstall it using the product code:

msiexec.exe /x {your-product-code-guid}

When you use the product code, it uses the cached MSI from C:\WINDOWS\Installer.
