Array in Asp.Net C#


Single - Dimensional Array


//---- Integer Datatype Array ----//



      int[] num = new int[5];

        num[0] = 0;
        num[1] = 1;
        num[2] = 2;
        num[3] = 3;
        num[4] = 4;

      Response.Write(num[3].ToString());


 OUTPUT



      ////   -------  String Datatype Array  ----- /////


        string[] week = new string[3] { "Sun""Mon""Tus" };
        for (int i = 0; i < week.Length; i++)
        {
            Response.Write(week[i] + ",");
        }



OUTPUT

                      
////   ------- For Loop   Integer Datatype Array   ----- /////


        int[] array = new int[4] { 10, 20, 30, 40 };

        array[0] = 10;
        array[1] = 20;
        array[2] = 30;
        array[3] = 40;

        for (int i = 0; i < array.Length; i++)
        {
            Response.Write(array[i] + ",");
        }



OUTPUT

 
////   -------  Boolean Datatype Array  ----- /////


        Array a = Array.CreateInstance(typeof(int), 5);

        a.SetValue(100, 0);
        a.SetValue(109, 1);
        a.SetValue(150, 2);
        a.SetValue(250, 3);
        a.SetValue(300, 4);

        int b = 5;

        Response.Write(Convert.ToBoolean(a.Length.Equals(b).ToString()));


           OUTPUT

 


         /// --- Sorting Array   ---  ///

        int[] numbers = { 9, 1, 5, 0, 9 };

        Array.Sort(numbers);

        foreach (int i in numbers)

            Response.Write (i+",");



            OUTPUT


 


        //  Create an Array with different data types //

        object[] Mix = new object[4];
        Mix[0] = 10;
        Mix[1] = "Dotnetdrizzles";
        Mix[2] = DateTime.Now;
        Mix[3] = DateTime.Now.AddDays(1).ToString();
        for (int i = 0; i < Mix.Length; i++)
        {
            Response.Write(Mix[i] + " , ");
        }


        
             OUTPUT


 
 ////   -------  Calculation in Integer Datatype Array  ----- /////


        int[] array11 = { 10, 20, 30 };

        Response.Write(array11[1] * 5);



             OUTPUT

                  
////   ------- Index  Find  String Datatype Array  ----- /////



        string[] array2 = new string[] { "A""B""C" };

        int Getindex = Array.IndexOf(array2, "B");

        Response.Write(Getindex.ToString());


        OUTPUT


             

            
////   -------   Array  Index Length ----- /////


        string[] array3 = new string[] { "A""B""C" };

        Response.Write(array3.Length + " "); // Empty Last Index Display

        Response.Write(array3.Length - 1); // Correct Index Length Display


         OUTPUT


             

 ////   -------  Resize Array Index Char Datatype Array  ----- /////


        char[] array4 = new char[5] { 'A''B''C''D''E' };
       
        Array.Resize(ref array4, 3);

        for (int i = 0; i < array4.Length; i++)
        {
            Response.Write(array4[i].ToString()+",");
        }

           
                 OUTPUT


                
////   -------  Foreach in Integer Datatype Array  ----- /////


        int[] array5 = new int[3] { 10, 30, 50 }; //array declaration
        foreach (int element in array5)
        {
            Response.Write(element);
        }


               OUTPUT

                
 ////   ------- Finding  Array  ----- /////


        string Check = "Drizzles";
