我想做的是if($s.Contains("Expired"))报告失败.简单...？:(问题我遇到的是它看起来像没有加载Contains方法,因为我得到这样的错误:

方法调用失败,因为[System.Object []]不包含名为"Contains"的方法.在行:1 char:12 + $ s.Contains <<<<("Expired")+ CategoryInfo:InvalidOperation :(包含:String)[],RuntimeException + FullyQualifiedErrorId:MethodNotFound

那么,我该怎么做才能阻止PowerShell将其展开为字符串？下面的实际ps脚本 -

$s = @(Invoke-Sqlcmd -Query "USE DB
       GO
       exec Monitor_TEST_ps 'EXPORT_RUN',NULL,20" `
       -ServerInstance testdb002\testdb_002
      )

if ($s.Contains("Expired"))   
{
    Write-Host "Expired found, FAIL."
}
else 
{
    Write-Host "Not found, OK." 
}

使用NHibernate的Windows服务中的多个SessionFactories

我有一个连接到2个DB的Webapp(一个核心,另一个是日志记录DB).

我现在必须创建一个Windows服务,它将使用相同的业务逻辑/数据访问DLL.但是,当我尝试在服务应用程序中引用2个会话工厂并调用factory.GetCurrentSession()方法时,我收到错误消息"没有会话绑定到当前上下文".

有没有人建议如何做到这一点？

public class StaticSessionManager
{
    public static readonly ISessionFactory SessionFactory;
    public static readonly ISessionFactory LoggingSessionFactory;

    static StaticSessionManager()
    {
         string fileName = System.Configuration.ConfigurationSettings.AppSettings["DefaultNHihbernateConfigFile"];
         string executingPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
         fileName = executingPath + "\\" + fileName;
         SessionFactory = cfg.Configure(fileName).BuildSessionFactory();

         cfg = new Configuration();
         fileName = System.Configuration.ConfigurationSettings.AppSettings["LoggingNHihbernateConfigFile"];
         fileName = executingPath + "\\" + fileName;
         LoggingSessionFactory = cfg.Configure(fileName).BuildSessionFactory();
    }

一个很好的F#代码库可供学习

I've been teaching myself F# for a while now. I've read Programming F# by Chris Smith (great book) and I've written a few small scripts for getting the job done here and there.

But IMO the best way to learn a new programming language—and more importantly, the idioms that come with it—is to read a good open source codebase written in that language. Naturally, writing code in that language is crucial, but in the beginning, you're basically struggling with your …
