'Declaration Public Event TraceEvent As MonitorEventHandler
public event MonitorEventHandler TraceEvent
Event Data
The event handler receives an argument of type MonitorEventArgs containing data related to this event. The following MonitorEventArgs properties provide information specific to this event.
Property | Description |
---|---|
CallStack | Gets the call stack of the monitor event. |
Description | Gets the description of a DbMonitor event. |
Duration | The time between the start and the end of the event. |
EventType | Gets DbMonitor event type. |
ExtraInfo | Gets the additional information for a DbMonitor event. |
TracePoint | Determines whether TraceEvent event occurs before or after the operation takes place. |
Example
The following sample shows how to enable and disable monitoring of database activity in your application.
static void OnEvent(object sender, MonitorEventArgs e) { if (e.TracePoint==MonitorTracePoint.BeforeEvent) { Console.WriteLine("Description: " + e.Description); Console.WriteLine(" Extra info: " + e.ExtraInfo); } } [MTAThread] static void Main(string[] args) { DynamicsConnection dynamicsConn = new DynamicsConnection( "Server=https://your_company.crm4.dynamics.com;User [email protected];Password=A123456789;"); DynamicsMonitor dynamicsMonitor = new DynamicsMonitor(); dynamicsMonitor.TraceEvent += new MonitorEventHandler(OnEvent); dynamicsMonitor.IsActive = true; DynamicsCommand dynamicsCommand = new DynamicsCommand("select count(*) from contact",dynamicsConn); dynamicsConn.Open(); Console.WriteLine(dynamicsCommand.ExecuteScalar()); dynamicsConn.Close(); dynamicsMonitor.TraceEvent -= new MonitorEventHandler(OnEvent); Console.ReadLine(); }
Sub OnEvent(ByVal sender As Object, ByVal e As MonitorEventArgs) If e.TracePoint = MonitorTracePoint.BeforeEvent Then Console.WriteLine("Description: " & e.Description) Console.WriteLine(" Extra info: " & e.ExtraInfo) End If End Sub <MTAThread()> _ Sub Main() Dim dynamicsConn As DynamicsConnection = New DynamicsConnection( _ "Server=https://your_company.crm4.dynamics.com;User [email protected];Password=A123456789;") Dim dynamicsMonitor As DynamicsMonitor = New DynamicsMonitor AddHandler dynamicsMonitor.TraceEvent, AddressOf OnEvent dynamicsMonitor.IsActive = True Dim dynamicsCommand As DynamicsCommand = New DynamicsCommand("select count(*) from contact", dynamicsConn) dynamicsConn.Open() Console.WriteLine(dynamicsCommand.ExecuteScalar()) dynamicsConn.Close() RemoveHandler dynamicsMonitor.TraceEvent, AddressOf OnEvent Console.ReadLine() End Sub
