How to return List of Array


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


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.
