That's because MemberList[i] is an object not a string.

So how to return object in String return type

Solution 3

Since ArrayList is a collection of objects, you have to cast the item to a string (you could just return the input string).
However, please note: it makes more sense to return the index of the found item (or -1 is it is not found).

C#

protected List<string> FindTargetMember(ArrayList MemberList,String TargetMember)
    {
        List<string> list = new List<string>();
        for (int i = 0; i < MemberList.Count; i++)
        {
            if (TargetMember.Equals(MemberList[i]))
            {
               list.Add(MemberList[i].Name.ToString());
// Assuming Name property is there in MemberList objeect. If it's not you can modify the code by yourself.
            }
        }
        return list;
}
