Iterate through all the classes in the project

Does that help This is exactly what interfaces are for -- you have common functionality in your objects and are guaranteed at compile time that that member is implemented. So long as each one of your classes objects implement a common interface, you can easily create a container for your objects, e.g.
code :
// Ensure your objects implement a common interface.
Dogs : ISaveable
Cats : ISaveable

...

// The interface (not shown) has a SaveOrder
Dogs.SaveOrder = 1;
Cats.SaveOrder = 2;

...

// Create a container that is capable of holding items implementing ISaveable 
List<ISaveable> saveItems = new List<ISaveable>();

...

// Add your items to your container
saveItems.Add(Dogs);
saveItems.Add(Cats);

...

// When it's time to save, simply enumerate through your container
foreach(var item in saveItems.OrderBy(q=>q.SaveOrder))
{
   // The interface guarantees that a Save method exists on each object
   item.Save();
}

How to iterate through nested classes?

help you fix your problem Another simple one! , I am guessing you are looking for something like the following.
code :
public class ClsMessage 
{
    public String username = "";
    public String password = "";
    public String request = "";

    public List<Parameters> parameters = new ArrayList<Parameters>();

    public static class Parameters {
        public String name = "";
        public String value = "";
    }
}

for(ClsMessage.Parameters param : clsMessage.parameters)
{
    ....
}

Iterate over an enum, which saves classes, then init the classes and put them into a map

will help you Use an upper bound on the wildcard:
code :
Class<? extends YourInterface>

iterate text file in php, multiple lines as one iteration or sub iterate perhaps

Does that help I am trying to convert a text based accounting file to an array using php. The structure of each verification line is the following: , I would go for regular expressions:
code :
$fileContent = file_get_contents($filePath);
if( preg_match_all('/^#VER(.*)\n{\n((^#TRANS.*\n)+)}/m', $fileContent, $matches) ){
   foreach($matches[0] as $i=>$match){
      echo 'VER    : '.$matches[1][$i].PHP_EOL;
      echo 'TRANSes: '.$matches[2][$i].PHP_EOL;
   }
}
$fileContent = file_get_contents($filePath);
if( preg_match_all('/^#VER(.*)\n{\n((^#TRANS.*\n)+)}/m', $fileContent, $matches) ){
   foreach($matches[0] as $i=>$match){
      echo 'VER:'.$matches[1][$i].PHP_EOL;
      if( preg_match_all('/^#TRANS (\d+) {} (-?\d+\.\d+) (\d{8}) "(.*)"/m', $matches[2][$i], $matches2) ){
         foreach($matches2[0] as $j=>$match2){
            $trans = array( 'account' => $matches2[1][$j]
                          , 'amount'  => $matches2[2][$j]
                          , 'date'    => $matches2[3][$j]
                          , 'text'    => $matches2[4][$j]
                          );
            print_r($trans);
         }
      }
   }
}

Iterate over classes with different structure

it fixes the issue Start by identifying common properties of your concepts when creating your model. You can create an abstract base class (in my example named "Vehicle") with the common properties, and then inherit in in the sub classes:
code :
public abstract class Vehicle
{
    public string Name { get; set; }
    public float Speed { get; set; }
}

public class Bus : Vehicle { }
public class Tram : Vehicle { }
public class Car : Vehicle { }
public class Bike : Vehicle
{
    public double Width { get; set; }
    public double Height { get; set; }
}
var vehicles = new List<Vehicle>
{
    new Bus { Name = "Bus", Speed = 180 },
    new Bus { Name = "Bus", Speed = 179 },
    new Bike { Name = "Bus", Speed = 180, Height = 23, Width = 32 },
    new Tram { Name = "Bus", Speed = 23 }
};

foreach (var vehicle in vehicles)
{
    // ..Output vehicle.Name & vehicle.Speed
    if (vehicle is Bike bike)
    {
        // Output bike.Height & bike.Width
    }
}
