将SPList.Items转化成Json格式。
 1 public static string GetJsonFormSplistItem(SPListItem item, string[] strArr)
 2         {
 3             string json = "{";
 4             for (int i = 0; i < item.ParentList.Fields.Count - 1; i++)
 5             {
 6                 string fieldName = item.ParentList.Fields[i].InternalName;
 7                 ArrayList ar = new ArrayList();//实例化一个ArrayList
 8                 ar.AddRange(strArr);//把数组赋到Arraylist对象
 9                 if (ar.Contains(fieldName))
10                 {
11                     if (item[i] != null)
