如何获取sql server 2005中数据库连接的详细列表?
database sql-server database-connection connection-pooling sql-server-2005
"我的网站是LIVE.这个问题与LIVE服务器上的配置会话超时有关,而与localhost无关."
我的会话过期很快就会出现问题.仅在2-5分钟内链接.我尝试了很多东西,最后决定将会话存储在"SQL Server"模式下
在我的web.config文件中,我有以下编码:
<sessionState mode="SQLServer" cookieless="false" timeout="45"
sqlConnectionString="data source=xxx.xx.xx.xxx;uid=xxxxxxx;pwd=xxxxxxxx"/>

我拥有服务器上ASPState表所需的所有表.您可以从下图中看到它.

但是当我运行我的应用程序时,它会抛出以下错误:
"无法使用SQL Server,因为SQL Server上未安装ASP.NET 2.0版会话状态,或者ASP.NET没有运行dbo.TempGetVersion存储过程的权限.如果ASP.NET会话状态架构没有已安装,请安装ASP.NET会话状态SQL Server 2.0或更高版本.如果已安装架构,请将dbo.TempGetVersion存储过程的执行权限授予ASP.NET应用程序池标识或Sql Server用户在sqlConnectionString属性中指定."

我无法理解确切的问题以及如何解决它.任何帮助将不胜感激.

我创建了一个继承自ValidationAttribute和IClientValidatable的验证属性.
一切似乎都运行正常,如果我在页面上放置验证摘要,则会显示错误.
但是我无法在与该属性相关的文本框旁边显示错误.
我想这是因为我需要将属性名称添加到验证结果中.
然而,这是失败的地方,因为我无法从validationContext获取成员名称.
有没有办法让这种情况发生?或者我错过了什么?
