异常的应用程序终止 [英] abnormal Application termination

问题描述

亲爱的所有人，

这是我的应用程序对应的一个大问题.我的应用程序异常终止，显示异常"Int32的超出范围的值".

但是我已经通过演示代码通过单击winform的按钮进行了测试:

Dear all,

It is a big problem corresponds my application. My application is abnormally terminated showing an exception "Out of range value of Int32".

But I have tested by the demo code with a button click on a winform:

int j;
j = Int32.MaxValue;
Random rnd = new Random(10000);
j = j * rnd.Next();
MessageBox.Show("Converted "+j);

但是应用程序并没有终止.

什么可能是叛国罪???:confused:

请帮帮我.

But the application didn''t terminate.

What might be th rreason???:confused:

Please help me.

推荐答案

不起作用的原因是您已经分配了Int32可以容纳的最高值:

the reason it isn''t working is that you already assign the highest value an Int32 can hold:

j = Int32.MaxValue;

然后尝试将其值设置为其自身乘以您随机生成的数字-结果太大，无法存储Int32.

我的猜测是您需要一个long而不是一个int.看看这篇文章，看看是否有帮助:

and then you try to set it''s value as itself multiplied by your randomly generated number - the result is too big for an Int32 to store.

my guess is you need a long instead of an int. have a look at this article and see if it helps:

示例:

long j;
j = Int32.MaxValue;
Random rnd = new Random(10000);
j = j * rnd.Next();
MessageBox.Show("Converted " + j);

因为如果您将Int32的值乘以2，则可能是Int64的值，这很长；)

如果有帮助，请投票并接受答案.

because if you multiple 2 Int32 value then it may be Int64 value, which is long ;)

我不认为您收到的错误来自Int32 溢出.实际上，您发布的"超出Int32的范围值"的消息甚至似乎都不是.NET异常消息.也许您正在尝试将此值插入数据库?也许是数据库抛出此消息异常.

I don''t think the error you are getting is from the Int32 overflow. In fact the message you posted "Out of range value of Int32" does not even seem to be a .NET exception message. Perhaps you are trying to insert this value into a database? And maybe it''s the DB that''s throwing an exception with this message.
