c# - 使用 C# 和存储过程解析文本文件并将其加载到数据库中

Question

我有一个持续错误的问题

“寻找过程或函数‘Cup_INSFuneralHome’需要参数‘@funeralhomename’，但未提供。”

我做了很多修改，但没有任何效果，所以我不得不从我在错误的区域寻找。

当我调试时，它似乎以正确的顺序提取了正确的信息。原始文本文件格式为:

公司名称
地址
城邦 zip
电话

我很纠结于此。我浏览了其他帖子，但未能找到我需要的内容，或者无法从众多“有点”相似的帖子中提取我需要的内容。恐怕问题就在我面前，但我就是看不到它。我需要一双全新的眼睛。所以我提前道歉。

过程代码:

ALTER procedure [dbo].[Cup_INSFuneralHome]
@funeralhomename nvarchar(50),
@addressone nvarchar(50),
@addresstwo nvarchar(50),
@CityName nvarchar(50),
@State nvarchar(10),
@Zipcode nchar(10),
@Telephone nchar(15),
@PrimaryContact nvarchar (50),
@EmailAddress nvarchar (50)
as

declare @cityid uniqueidentifier
declare @stateid uniqueidentifier 

select @cityid = (select cityid from [city] where CityName=(@CityName)) 
select @stateid = (select stateid from [State] where StateCode=ltrim(rtrim(@State)))

insert funeralhome(funeralhomename, addressone, addresstwo, cityid, stateid, zipcode,  telephone, PrimaryContact, EmailAddress)
values (@funeralhomename, @addressone, @addresstwo, @CityName, @State, @ZipCode,     @Telephone, @PrimaryContact, @EmailAddress)

您没有将 sql 参数添加到 cmd 对象；-)
