EntityFramework过程或函数''期望参数''，未提供

I apologise for asking just a basic question, however I cannot find the cause of this error.

我为问一个基本问题而道歉，但是我找不到这个错误的原因。

I am using Entity Framework to execute a Stored Procedure, and I am passing in four parameters, however the SQL Database seems to reject them. Can anyone point me in the right direction?

我正在使用Entity Framework来执行存储过程，并且我传递了四个参数，但SQL数据库似乎拒绝它们。谁能指出我正确的方向？

My code:

我的代码：

ObjectResult<SearchDirectoryItem> resultList = container.ExecuteStoreQuery<SearchDirectoryItem>("SearchDirectoryEntries",
            new SqlParameter("@DirectoryId", search.DirectoryId),
            new SqlParameter("@Latitude", point.Latitude),
            new SqlParameter("@Longitude", point.Longitude),
            new SqlParameter("@Range", search.RangeMiles));

Which produces the error:

哪会产生错误：

Procedure or function 'SearchDirectoryEntries' expects parameter '@DirectoryId', which was not supplied.

过程或函数'SearchDirectoryEntries'需要参数'@DirectoryId'，这是未提供的。

The SQL generated is:

生成的SQL是：

exec sp_executesql N'SearchDirectoryEntries',N'@DirectoryId int,@Latitude decimal(7,5),@Longitude decimal(6,5),@Range int',@DirectoryId=3,@Latitude=53.36993,@Longitude=-2.37013,@Range=10

The stored procedures is:

存储过程是：

ALTER PROCEDURE [dbo].[SearchDirectoryEntries]
@DirectoryId int,
@Latitude decimal(18, 6),
@Longitude decimal(18, 6),
@Range int

Many Thanks.

非常感谢。

The commandText param in your query is incorrect. It should be a call to a stored procedure with parameters instead of just stored procedure name:

查询中的commandText参数不正确。它应该是一个带参数的存储过程调用，而不仅仅是存储过程名称：

ObjectResult<SearchDirectoryItem> resultList = container.ExecuteStoreQuery<SearchDirectoryItem>(
    "Exec SearchDirectoryEntries @DirectoryId, @Latitude, @Longitude, @Range",
     new SqlParameter("DirectoryId", search.DirectoryId),
     new SqlParameter("Latitude", point.Latitude),
     new SqlParameter("Longitude", point.Longitude),
     new SqlParameter("Range", search.RangeMiles));

Also don't forget to remove '@' from SqlParameter constructor.

另外，不要忘记从SqlParameter构造函数中删除“@”。
