C#尝试在Infopath 2007表单中捕获错误 [英] C# try catch error in Infopath 2007 form

问题描述

您能否解释一下该错误可能是什么:当用户向Clientpoint提交客户端Infopath表单(未启用网络)时，C#尝试捕获该错误消息:

Can you please explain what this error might be: when a user submits a client Infopath form (not web-enabled) to Sharepoint the C# try catch spits out this error message:

 值不能为空-参数名称:键"

 "Value cannot be null - Parameter name: key"

谢谢
Steve

Thanks
Steve

推荐答案

欢迎来到MSDN论坛.

Welcome to the MSDN Forums.

当您(或调用堆栈中的某处)将null作为不可为空的参数传递时，即参数不能为null时，会发生此错误.

This error occures when you (or somewhere in call stack) pass null as a not nullable parameter, i.e. the parameter cannot be null.

我建议跟踪代码以查找不需要可为空的参数的函数，然后查看在哪里传递了null.

I recommend tracing the code to finding the function which needs not nullable parameter, then see where null have been passed.

希望这对您有所帮助.
