.net自带的水晶报表可以支持多个用户同时访问吗，有用户数量的限制吗？
不注册好像是有用户数目限制的，记得好像是5个
可以，不過你要先改注冊表消除並發限制，像這樣：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Crystal Decisions\10.2\Report Application Server\Server]
“PrintJobLimit”=”1000”
[HKEY_LOCAL_MACHINE\SOFTWARE\Crystal Decisions\10.2\Report Application Server\InprocServer]
“PrintJobLimit”=”1000”
[HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.0\Report Application Server\Server]
“PrintJobLimit”=”1000”
[HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.0\Report Application Server\InprocServer]
“PrintJobLimit”=”1000”
[HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Report Application Server\Server]
“PrintJobLimit”=”1000”
[HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 11.5\Report Application Server\InprocServer]
“PrintJobLimit”=”1000”
