C# System.FormatException'；在mscorlib.dll中发生，但未在用户代码错误中处理

这个问题在前面已经讨论过了，但这并不能帮助我解决问题

下面是使投资处于非活动状态的存储过程

ALTER  procedure [dbo].[mark_inactive]                  
@order_id int,                 
@intResult int output                  
as                  
BEGIN transaction               

Declare @Error as int

update investment_orders set investment_active = 0 where order_id = @order_id


-- if error in saving details                    
Select @Error = @@error                    
 if(@Error<>0)                    
 Begin                    
  Set @intResult = 0                    
  rollback transaction            
  return                      
 End          
commit transaction                    
return @intResult 

如果有任何错误，我很抱歉。请帮我解决这个问题

谢谢

您在成功更新后编写的存储过程中没有返回任何值

你的程序应该是这样的

ALTER  procedure [dbo].[mark_inactive]                  
@order_id int,                 
@intResult int output                  
as                  
BEGIN transaction               

Declare @Error as int

update investment_orders set investment_active = 0 where order_id = @order_id;
SET @intResult = 1; // 1 OR whatever desired value you wanna return

-- if error in saving details                    
Select @Error = @@error                    
 if(@Error<>0)                    
 Begin                    
  Set @intResult = 0                    
  rollback transaction            
  return                      
 End          
commit transaction                    
return @intResult 

ALTER过程[dbo]。[mark_inactive]
@订单号，
@intResult int输出
作为
开始交易
将@Error声明为int
更新投资\u订单设置投资\u活动=0，其中订单\u id=@order\u id；
设置@intResult=1；//1或任何想要返回的值
--如果保存详细信息时出错
选择@Error=@@Error
如果（@Error0）
开始
设置@intResult=0
回滚事务
返回
终点
提交事务
返回@intResult

错误发生在哪一行？ExecuteOnQuery或Int32.Parse？谢谢您的回复。Int32.Parse section returning error在尝试解析之前，我会先检查out参数的内容并确保它有值。@bangla Tiger-我很高兴它能工作！！请将其标记为有帮助的答案，以便对其他人也有帮助！！：）-我是新来的，不知道如何将它标记为有用。你能告诉我吗？
