组装json对象

public string strTree(DataTable dt, string type, string state)
        {
            string strjosn = "";
            foreach (DataRow dr in dt.Rows)
            {
                if (string.IsNullOrEmpty(strjosn))
                {
                    strjosn = "{"id":"" + dr[1] + "","text":"" + dr[0] + "","state":"" + state +
                              "","attributes":{"type":"" + type + ""}}";
                }
                else
                {
                    strjosn += "," + "{"id":"" + dr[1] + "","text":"" + dr[0] + "","state":"" + state +
                               "","attributes":{"type":"" + type + ""}}";
                }
            }
            strjosn = "[" + strjosn + "]";
            return strjosn;
        }
