如何让Linq to SQL识别动态存储过程的结果集？

CREATE PROCEDURE GetDynamicResultSet
    @param1 INT,
    @param2 NVARCHAR(50)
AS
BEGIN
    SELECT * FROM YourTable WHERE Column1 = @param1 AND Column2 = @param2
END

public class YourDataContext : DataContext
{
    public YourDataContext(string connectionString) : base(connectionString) { }

    [Function(Name = "dbo.GetDynamicResultSet")]
    [Returns(Type = typeof(YourResultType))]
    public IQueryable<YourResultType> GetDynamicResultSet(int param1, string param2)
    {
        var parameters = new ObjectParameter[]
        {
            new ObjectParameter("param1", param1),
            new ObjectParameter("param2", param2)
        };

        return this.ExecuteQuery<YourResultType>("GetDynamicResultSet", parameters);
    }
}

using (var context = new YourDataContext(connectionString))
{
    var result = context.GetDynamicResultSet(1, "example").ToList();
}
