How to check if a particular version of flash player is installed or not in C#.?

Question

I want to check from my code if a particular version of flash player is installed or not. I used the following code

using Microsoft.Win32

RegistryKey RK = R

Adobe's old (pre 10) IE Flash detection code used to test in VBScript if it could instantiate object ShockwaveFlash.ShockwaveFlash.. If it's just the major version you want to test, you can check for those keys under HKCR, e.g. HKEY_CLASSES_ROOT\ShockwaveFlash.ShockwaveFlash.10.

SWFObject instantiates the version-less object name, ShockwaveFlash.ShockwaveFlash, and queries its $version property. To do this in C#:

// Look up flash object type from registry
var type = Type.GetTypeFromProgID("ShockwaveFlash.ShockwaveFlash");
if (type == null)
{
  // No flash
  return;
}

// Create a flash object to query
// (should probably try/catch around CreateInstance)
var flashObject = Activator.CreateInstance(type);
var versionString = flashObject.GetType()
                      .InvokeMember("GetVariable", BindingFlags.InvokeMethod,
                                    null, flashObject, new object[] {"$version"})
                    as string;
// e.g. "WIN 10,2,152,26"

// Clean up allocated COM Object
Marshal.ReleaseComObject(flashObject);
