C# Application Scanning

问题

I want to scan and get all the Application files in my computer.
I know how to get them, but I want only the applications which are Executable (except for Installers).

Basically, what I want is the same function steam uses. Example:

回答1:

If you want to get the list of installed applications on your system, you can query the registry. Refer to Get installed applications in a system for an example.

回答2:

You can use this code to find all exes recursively in a directory

    DirectoryInfo dirInfo = new DirectoryInfo(@"C:\Program Files");
    var exeFiles = dirInfo.EnumerateFiles("*.exe", SearchOption.AllDirectories);

    foreach ( var exeFile in exeFiles )
    {
        Console.WriteLine( exeFile );
    }

Depending on you definition of executable you might have to also do *.com , *.bat etc etc. There is no way to distinguish between an installer exe vs regular exe file though. You might have to apply some heuristics
