ASP.NET ObjectDataSource could not find a non-generic method that has parameters
提问by Diluen Cheong
I am using a FormView control on an ASP.Net page with an ObjectDataSource that is linked to a Business Tier component connected to stored procedures in the SQL Server. I am getting the ObjectDataSource could not be found error and I have made sure that all my components contain the parameters (and that they exist).
我在 ASP.Net 页面上使用 FormView 控件，其 ObjectDataSource 链接到连接到 SQL Server 中存储过程的业务层组件。我收到无法找到 ObjectDataSource 错误，并且我已确保我的所有组件都包含参数（并且它们存在）。
I can't figure out why it can't find the parameters even though they are there?
我不明白为什么它找不到参数，即使它们在那里？
Stored Procedure:
存储过程：
UPDATE [Anime_List] SET [Name] = @name, [AnimeImage] = @anime_image, [Synopsis] = @synopsis, [Type] = @type, [Episodes] = @episodes, [Genres] = @genres, [Rating] = @rating WHERE (([AnimeID] = @original_animeID));
Business Component:
业务组成：
[DataObjectMethod(DataObjectMethodType.Update)]
public static void UpdateAnimeList(string name, string anime_image, string synopsis,
string type, short episodes, string genres, decimal rating, int original_animeID,
int animeID)
{
animeList.AnimeListUpdateCommand(name, anime_image, synopsis, type, episodes,
genres, rating, original_animeID, animeID);
}

It seems to be failing looking for another AnimeImage.
寻找另一个 AnimeImage 似乎失败了。
I'd suggest matching the casing (capitalization, don't use under_case) and order of the arguments the error page is asking for.
我建议匹配大小写（大写，不要使用 under_case）和错误页面要求的参数顺序。
Something like
就像是
[DataObjectMethod(DataObjectMethodType.Update)]
public static void UpdateAnimeList(string name, string **animeImage**, string synopsis,
string type, short episodes, string genres, decimal rating, int original_animeID,
int animeID) {
...
}
