SQL Server 的目录视图中是否有任何内容可以为您提供存储过程的列表，这样select name from sys.procedures还会告诉您每个过程需要多少参数？Intellisense 将为您提供参数的名称，Visual Studio 也知道。有没有更好的方法来获得存储过程的结果以及每个过程采用的参数的数量（和/或名称）？

我想如果他们解析了 sp_helptext 'sprocName' 就可以做到这一点，但我认为有更好的方法来做到这一点。

再挖一点挖，想出了

;with x
as
(
SELECT 
    p.name AS Parameter,        
    t.name AS [Type],
    sp.name
FROM sys.procedures sp
JOIN sys.parameters p 
    ON sp.object_id = p.object_id
JOIN sys.types t
    ON p.system_type_id = t.system_type_id
)
select name,Parameter,COUNT(*)
from x
group by name,Parameter

这将完成这项工作。

试试这个：

select * from information_schema.parameters
where specific_name='your_procedure_name'

您可以像这样获取参数信息：

declare @ProcedureName sysname;
set @ProcedureName = '[dbo].[YourProcedureName]';

select  sp.name, 
        spa.name, 
        spa.is_output 
from    sys.procedures sp
join    sys.parameters spa on
        sp.object_id = spa.object_id
where   sp.object_id = object_id(@ProcedureName);

如果，正如您所提到的，您为此使用 .NET 语言，您可以使用SqlCommandBuilder 的DeriveParameters方法。这样您就不必在后端编写任何内容，而只需使用 .NET 代码即可。
