asp.net的web页面，数据量过多是提交失败，对策：
web.config文件中，增加
复制代码 代码如下:
<appSettings>
...
<add key="aspnet:MaxHttpCollectionKeys" value="5000" />
...
</appSettings>
<appSettings>
...
<add key="aspnet:MaxHttpCollectionKeys" value="5000" />
...
</appSettings>
<appSettings>
...
<add key="aspnet:MaxHttpCollectionKeys" value="5000" />
...
</appSettings>
