动态增加SqlParameter[]中的元素，自己的记录

                sqlsp = "BlogArticle_Update";
                SqlParameter[] param = {
                                        new SqlParameter("Content",Content.Value),
                                    };
                //重构数组
                SqlParameter[] param2;
                if (IsDefineWeight == "1")
                {
                    int newNum = param.Length + 1;
                    param2 = (SqlParameter[])Redim(param, newNum);
                    param2[newNum - 1] = new SqlParameter("Weight", weight.Text);
                }
                else
                {
                    param2 = param;
                }

                DAL.dbsp.ExecuteNonQuery(sqlsp, param2);

自己的记录

        public static Array Redim(Array origArray, Int32 desiredsize)
        {
            //确定每个元素类 型    
            Type t = origArray.GetType().GetElementType();
            //创建一个含有期望元素个数的新数组  
            //新数组的类型必须匹配原数组的类型  
            Array newArray = Array.CreateInstance(t, desiredsize);
            //将原数组中的元素拷贝到新数组中  
            Array.Copy(origArray, 0, newArray, 0, Math.Min(origArray.Length, desiredsize));
            return newArray;
        }
