是否可以将输出参数与ExecuteQuery一起使用?

Alper Ozcetin是对的,您可以在*.dbml中映射StoredProcedures,并且可以使用StoredProcedures作为方法。

下面是使用AdventureWorks DB执行此操作的演示,适用于vs2008和vs2010

在AdventureWorks中,我创建了以下程序

CREATE PROC sp_test (@City  Nvarchar(60) , @AddressID int out  )
AS
SELECT TOP 10 * FROM Person.Address where City = @City
select  top 1  @AddressID  = AddressID FROM Person.Address where City = @City

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.Linq;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {


            DataClasses1DataContext dc = new DataClasses1DataContext("SomeSQLConnection);

            int? AddressID = null;
            ISingleResult<sp_testResult> result = dc.sp_test("Seattle", ref AddressID);

            foreach (sp_testResult addr in result)
            {
                Console.WriteLine("{0} : {1}", addr.AddressID, addr.AddressLine1);
            }
            Console.WriteLine(AddressID);


        }
    }
}

这将导致以下输出

23 : 6657 Sand Pointe Lane
91 : 7166 Brock Lane
92 : 7126 Ending Ct.
93 : 4598 Manila Avenue
94 : 5666 Hazelnut Lane
95 : 1220 Bradford Way
96 : 5375 Clearland Circle
97 : 2639 Anchor Court
98 : 502 Alexander Pl.
99 : 5802 Ampersand Drive
13079

您会注意到sp_测试方法的输入是 ref

我不确定,但您可以尝试在查询中声明变量,将其作为输出参数传递,然后选择它:

//assuming you out parameter is integer
string query = "DECLARE @OUT INT ";
query += " Exec myStoredProcedure ";
for (int i = 0; i < parameters.Count - 1; i++) {
  query += " {" + i + "},";
}
//assuming the output parameter is the last in the list
query += " @OUT OUT ";
//select value from out param after sp execution
query += " SELECT @OUT"

您不需要在ExecuteQuery中为StoredProcess编写原始SQL。您可以在*.dbml中映射StoredProcess,并且可以将StoredProcess用作方法。
