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;
        }
