How to return List of Array

Introduction:-

                     Here I have explained how to return array list in webmethod.

Description:-

                  In my previous article I have explained AutoComplete text using Jquery and web services , How to bind state by selecting country dropdownlist using webmethod in Asp.net , How to select, update, insert data in database using Json, Jquery and Webservices , Ajax tab inside a gridview , Data binding in dropdownlist using Jquery , How to calculate differencebetween two dates using JQuery?

Here I am going to explain how return array list. If you are using Ajax method to bind a

dropdownlist or any grid controls, then you have to return some value from webmethod.  

Where as you must return a list value to your ajax success function to bind that control.

For this I am using here array list as return value.

Here is the web method I have used for this example:-

 [WebMethod(EnableSession = true)]

    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]

    public ArrayList GetBranchForClassCourse(int classCourseId)

    {

        instituteBO iBO = new instituteBO();

        iBO.Operation = "GetSyllabusBranchNm";

        iBO.ClsCrsID = Convert.ToInt32(classCourseId);

        DataTable dataTable = iBO.GetSyllabusBranchNm(iBO);

        ArrayList list = new ArrayList();

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

        {

            list.Add(new ListItem(dataTable.Rows[i][1].ToString(), dataTable.Rows[i][0].ToString()));

        }

        return list;

}

 Here is the image which will shows that it is returning 4 records as array list during debug mode.
