mingxis:
[{"规格":"30*20cm","单位":"张","产品ID":"1c3710391809490cb56db732848b84b7","产品类别一":"办公用品","产品类别二":"印刷品","产品名称":"广告海报","产品编码":"2019-10-290535","GUID":"ET8iNyTqNTrRxeGHzRkIfS5PkfHPPpEy","入库ID":"M1mZm8cxzTezv3yYVJxAPzkZiw9KgoOX","品牌":"3M","产品图片":"045.png","出库ID":"K6oOcXcBhZi6z9SZzSuE8EAgw6WTfFAx","目前库存":"10"},{"规格":"20ml","单位":"瓶","产品ID":"2a2a016760444ccf9efefb437575b675","产品类别一":"医疗耗材","产品类别二":"常规耗材","产品名称":"碘甘油","产品编码":"10WZ170727004","GUID":"S5b4A3JKdYBAIwQjj8ShxFC30oIcXkpB","入库ID":"M1mZm8cxzTezv3yYVJxAPzkZiw9KgoOX","品牌":"","产品图片":"004.png","出库ID":"K6oOcXcBhZi6z9SZzSuE8EAgw6WTfFAx","目前库存":"20"}]
这个动态生成的json,我想拼接成插如数据库的语句
For Each ep As JToken In JArray.Parse(mingxis)
cmd.CommandText = "Insert Into 产品出库明细 (规格,单位,产品ID,产品类别一,产品类别二,产品名称,产品编码,GUID,出库ID,品牌,出库数量,产品图片,入库ID,目前库存,说明) Values(\'" & ep("规格").ToString() & "\',\'" & ep("单位").ToString() & "\',\'" & ep("产品ID").ToString() & "\',\'" & ep("产品类别一").ToString() & "\',\'" & ep("产品类别二").ToString() & "\',\'" & ep("产品名称").ToString() & "\',\'" & ep("产品编码").ToString() & "\',\'" & ep("GUID").ToString() & "\',\'" & ep("出库ID").ToString() & "\',\'" & ep("品牌").ToString() & "\',\'" & ep("出库数量").ToString() & "\',\'" & ep("产品图片").ToString() & "\',\'" & ep("入库ID").ToString() & "\',\'" & ep("目前库存").ToString() & "\',\'" & ep("说明").ToString() & "\')"
index += cmd.ExecuteNonQuery()
Next
但是这个语句发现动态进来的json进来的键值对,会变,所以生成错误

想怎么处理？

按照{} 一对 根据键值对生成一条 插入数据的语句

For Each ep As JToken In JArray.Parse(mingxis)
dim sql as string = "Insert Into 产品出库明细 ("
dim sqlvalue as string = "Values("
for each jp as object in ep
sql = sql & jp.name & ","
sqlvalue = sqlvalue & "\'" & jp.value & "\',"
next
dim sql2 as string = sql.trim(",") & ") " & sqlvalue.trim(",") & ")"
msgbox(sql2)

我靠 我犯了一个低级错误,我把插入语句 嵌套进去了.笨死了
