C # Common algorithms: Dynamic Object

The Dynamic object is contained in. Net4.0, which allows us to change its type at runtime, with this snake balm. What are the problems we can't solve? Let's take a look at some examples of its use:

var type and dynamic type

public static void Testdynamicobject ()  
{   
    //var object and dynamic Object  
    var varobj = ' This is a var object '; C4/>dynamic Dyobj = "This is a dynamic object";  
      
    Console.WriteLine (varobj);  
    Console.WriteLine (dyobj);  
      
    Dyobj = new string[] {dyobj, "I also can do it liking this!"};  
    Console.WriteLine (Dyobj[0]);  
    Console.WriteLine (Dyobj[1]);  
      
    /*out the ' is ' 
        a var object is a 
        dynamic object 
        I also can do it Liki ng this! 
     */
}

Expandobject

 public static void Testexpandobject () {Dynamic Data = new ExpandoObject (); Data.  
            FirstAttribute = "FirstAttribute"; Data.  
            Secondattribute = "Secondattribute"; Data.  
      
            Thirdattribute = "Thirdattribute";  
            ArrayList nums = new ArrayList (); for (int i = 1; I <= i++) {nums.  
            ADD (i); } data.  
      
            Nums = Nums; foreach (int tmp in data.)  
            Nums) {Console.WriteLine (TMP); } Console.WriteLine (data.  
            FirstAttribute); Console.WriteLine (data.  
            Secondattribute); Console.WriteLine (data.  
      
            Thirdattribute);  
            Action GB = () => {Console.WriteLine ("This was dynamic method."); Data.  
            MYMETHOD2 = GB; Data.  
      
            MYMETHOD2 (); Action<string> ghostbear = a => COnsole.  
            WriteLine (a); Data.  
            MyMethod = Ghostbear; Data. MyMethod ("go! Go!  
      
            Fighting! "); 
                /*out put 1 2 3 4 5 
                6 7 8 9 FirstAttribute 
                Secondattribute Thirdattribute this are dynamic method. Go! Go! 
     
             fighting! */
        }
