How to use C# List Using in Asp.Net

                     C# List

C# List class is used to collection of values add,remove,count,index conditions represent . this access Int,String,bool like datatypes supports . list add to array values and display specific order.
List class is a collection and defined in the System.Collections.Generic namespace .

Code

List class add the int datatype values

List <int> li =new List<int>();

        li.Add(100);

        li.Add(200);

        li.Add(300);

        for (int i = 0; i < li.Count; i++)

        {

            Response.Write(li[i].ToString() + "<br/>");

          

        }

 Code

List class add the String datatype values

List <string> li =new List<string>();

        li.Add("Dotnet");

        li.Add("drizzles");

        li.Add(".blogspot.in");

        foreach (string str in li)

        {

            Response.Write(str.ToString());

          

        }

 Code

List class copy the Array  values

// Array copy to list

        int[] arr=new int[3];

        arr[0]=777;

        arr[1] = 888;

        arr[2] = 999;

        List <int> li =new List<int>(arr); // arr copy to list

      

        foreach (int Value in li)

        {

            Response.Write(Value.ToString() + ",");

          

        }

Code

List class add the int datatype array values to display

        List <int> li =new List<int>(new int[] {100,1000,1000}); // array to list

        for (int i = 0; i < li.Count;i++ )

        {

            Response.Write(li[i].ToString() + ",");

        }

Code

List class check the indexof position for int,bool,string datatypes 

List <int> li =new List<int>(new int[] {100,1000,1000}); // array to list

        List <bool> bo = new List<bool> (new bool[] {true,false});

        List<string> str = new List<string>(new string[] { "Dotnet", "drizzles", ".blogspot.in" });

        int index = li.IndexOf(1000);

       

        Response.Write("Integer Index Position="+index + "<br/>");

       

        int BoolIndex =bo.IndexOf(true);

        Response.Write("Bool Index Position=" + BoolIndex + "<br/>");

        int StrIndex = str.IndexOf(".blogspot.in");

        Response.Write("String Index Position=" + StrIndex.ToString() + "<br/>");

Code

List class check the values contain from list using bool datatypes  output:false

List <int> li =new List<int>();

        li.Add(100);

        li.Add(200);

        li.Add(300);

        

        bool Value=li.Contains(400);

        Response.Write(Value.ToString() + "<br/>");
