Use of Params Modifier in C#.NET

While victimization the perform member, any numbers of parameter (including none) might seem within the job perform supported want. thus to possess a versatile perform we are able to use params modifier whereas writing the definition of functions.

params keyword specify a way parameter that takes AN argument wherever the numbers of arguments become variable means that parameter arrays enable a variable numbers of arguments to be passed in to a perform. it's additionally sort compatible with the parameters. for instance we are able to send integers , characters, strings at a time to the perform that has the params modifier declared.

private void ParamsUsed()
        {
            ArrayList   listForObject = new ArrayList();
            ArrayList   listForInt = new ArrayList();

            int[] myarray = new int[] { 10, 11, 12 ,13, 14, 15, 16 };
            
            listForObject = UseParams2(100, 200, 'A', "amit");
            listForInt = UseParams(myarray);

            DropDownList1.DataSource = listForObject;
            DropDownList1.DataBind();

            DropDownList2.DataSource = listForInt;
            DropDownList2.DataBind();

        }

public static ArrayList UseParams2(params object[] list)

        {
            ArrayList listT = new ArrayList();
            for (int i = 0; i < list.Length; i++)
            {
                listT.Add(list[i]);
            }
            return listT;
         
        }

public static ArrayList UseParams(params int[] list)
        {
            ArrayList listT = new ArrayList();
            for (int i = 0; i < list.Length; i++)
            {
                listT.Add(list[i]);
            }
            return listT;
        }
