示例1: MyCompanyEventSource
//引入命名空間
using System.Diagnostics.Tracing;
using System.Collections.Generic;
namespace Demo1
{
class MyCompanyEventSource : EventSource
{
public static MyCompanyEventSource Log = new MyCompanyEventSource();
public void Startup() { WriteEvent(1); }
public void OpenFileStart(string fileName) { WriteEvent(2, fileName); }
public void OpenFileStop() { WriteEvent(3); }
}
class Program
{
static void Main(string[] args)
{
string name = MyCompanyEventSource.GetName(typeof(MyCompanyEventSource));
IEnumerable<EventSource> eventSources = MyCompanyEventSource.GetSources();
MyCompanyEventSource.Log.Startup();
// ...
MyCompanyEventSource.Log.OpenFileStart("SomeFile");
// ...
MyCompanyEventSource.Log.OpenFileStop();
}
}
