************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
什么原因啊,急......谢谢

[风之影子]

你在运行什么的时候跳出来的

[深海之蓝]

数组越界

[ChrisAK]

ArgumentOutOfRange...参数超出其值所允许的范围.
例如一个int参数被限定在0~10之间而你传了个100过去
就会抛出这个异常.从错误信息来看是startIndex这个参
数.至于怎么办...不贴出代码神仙来了也帮不了你.

[深海之蓝]

数组的某个索引小于0
第一句话这么说的

[ChrisAK]

[Quote=引用 2 楼 llwinnner 的回复:]
数组越界
[/Quote]数组越界我没记错的话是IndexOutOfRangeException

[alexfan53888]

偶尔会有.代码一大堆.
我用代码跑不出来,到客户机安装后,运行有时会跳出这个错误,重新装一下后,又OK.

[alexfan53888]

楼上说:startIndex这个超出范围,但我在代码里面又找不到这个关键字啊

[ChrisAK]

[Quote=引用 7 楼 alexfan53888 的回复:]

[/Quote]System.ArgumentOutOfRangeException: StartIndex cannot be less than zero.
Parameter name: startIndex
-------------------------------
StartIndex不能小于0.
你在代码里当然找不到这个关键字,
C#传参数又不要你指明参数名称.

话说出错调试的时候不是会中断在出错的地方么?
不用找啊?

[alexfan53888]

用代码跑不出来错误.制作成安装包,在客户端安装后,有时会出现上面的错误.

startIndex是负数，值为空，截取字符串错误
看看FrmConvert.BtnUpload_Click
