Run code if no catch in Try/Catch

When I use Try/Catch, is there a way just like If/Else to run code if there is no error is detected and no Catch?

try
{
    //Code to check
}
catch(Exception ex)
{
    //Code here if an error
}

//Code that I want to run if it's all OK ?? 

finally
{
    //Code that runs always
}
