我有代码:
var listener = new TextWriterTraceListener(@"C:\logs\1.log", "myListener")
{
TraceOutputOptions = TraceOptions.DateTime
};
Trace.Listeners.Add(listener);
Trace.TraceInformation("Starting...");
输出为 MyProgram.vshost.exe Information: 0 : Starting...DateTime=2016-07-07T10:43:10.5147858Z
如何告诉监听器不要打印进程名称?
最佳答案
不幸的是,这似乎是不可能的。
我反编译了那个监听器,发现没有这个选项。 但仍有希望。
您可以像这样实现自己的监听器:
public class MyListener : TextWriterTraceListener {
public MyListener(Stream s) : base(s) {
}
public MyListener(string s, string s1) : base(s, s1) {
}
public override void TraceEvent(TraceEventCache eventCache, string source, TraceEventType eventType, int id, string message) {
if (this.Filter != null && !base.Filter.ShouldTrace(eventCache, source, eventType, id, message, null, null, null))
return;
this.WriteLine(message);
this.WriteFooter(eventCache);
}
private bool IsEnabled(TraceOptions opts) {
return (uint)(opts & this.TraceOutputOptions) > 0U;
}
private void WriteFooter(TraceEventCache eventCache) {
if (eventCache == null)
return;
this.IndentLevel = this.IndentLevel + 1;
if (this.IsEnabled(TraceOptions.ProcessId))
this.WriteLine("ProcessId=" + (object)eventCache.ProcessId);
if (this.IsEnabled(TraceOptions.LogicalOperationStack)) {
this.Write("LogicalOperationStack=");
Stack logicalOperationStack = eventCache.LogicalOperationStack;
bool flag = true;
foreach (object obj in logicalOperationStack) {
if (!flag)
this.Write(", ");
else
flag = false;
this.Write(obj.ToString());
}
this.WriteLine(string.Empty);
}
if (this.IsEnabled(TraceOptions.ThreadId))
this.WriteLine("ThreadId=" + eventCache.ThreadId);
if (this.IsEnabled(TraceOptions.DateTime))
this.WriteLine("DateTime=" + eventCache.DateTime.ToString("o", (IFormatProvider)CultureInfo.InvariantCulture));
if (this.IsEnabled(TraceOptions.Timestamp))
this.WriteLine("Timestamp=" + (object)eventCache.Timestamp);
if (this.IsEnabled(TraceOptions.Callstack))
this.WriteLine("Callstack=" + eventCache.Callstack);
this.IndentLevel = this.IndentLevel - 1;
}
}
