SQL数据库连接语句

一般的远程访问的写成这样：

Data Source=IP ;Initial Catalog=数据库名 ;UserID= 用户名 ;Password=密码

本地访问的写成这样：

Data Source=(local);Initial Catalog=数据库名 ;UserID= 用户名 ;Password=密码

如果是本地的，通过windows组件验证的（也就是没有用户名，密码的）写成这样：

Data Source=(local);Initial Catalog=数据库名 ;Integrated Security=True

如果不是默认的实例，假如实例名是SQLEXPRESS，写成这样：

Data Source=(local)/SQLEXPRESS ;Initial Catalog=数据库名 ;Integrated Security=True

 WorkflowIdled 事件

.NET Framework 类库

WorkflowRuntime. . :: . WorkflowIdled 事件

更新：2007 年 11 月

在工作流实例进入空闲状态后发生

static void Main()
{
    string connectionString = "Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;" ;

using (WorkflowRuntime workflowRuntime = new WorkflowRuntime())
    {
        ExternalDataExchangeService dataService = new ExternalDataExchangeService();
        workflowRuntime.AddService(dataService);
        dataService.AddService(expenseService);

workflowRuntime.AddService(new SqlWorkflowPersistenceService(connectionString));
        workflowRuntime.StartRuntime();

workflowRuntime.WorkflowCompleted += OnWorkflowCompleted;
        workflowRuntime.WorkflowTerminated += OnWorkflowTerminated;
        workflowRuntime.WorkflowIdled += OnWorkflowIdled;
        workflowRuntime.WorkflowAborted += OnWorkflowAborted;

Type type = typeof(SampleWorkflow1);
        WorkflowInstance workflowInstance = workflowRuntime.CreateWorkflow(type);
        workflowInstance.Start();

waitHandle.WaitOne();

workflowRuntime.StopRuntime();
    }
}
