C#调用SQL中的存储过程中有output参数

 想在存储过程中返回是否出错，回滚，就查了一些资料，以下方不整理一下

Alter proc Sp_AutoTenderTrialAll

@isAuto int ,

@id int,

@AdminId int ,

@AdminName varchar(250),

@output int output

as

Begin

   set  @output=1

end

/*************C#************/

           {

               string strsql = string.Format("Sp_AutoTenderTrialAll");

               SqlCommand cmd = new SqlCommand(strsql, conn); //链接

               cmd.Parameters.Add(new SqlParameter("@isAuto", SqlDbType.Int));

               cmd.Parameters["@isAuto"].Value = auto;
