.NET 跟踪不适用于 Diagnostics.TraceSource,仅适用于 Diagnostics.Trace

我正在尝试设置 .NET 跟踪。我可以通过 System.Diagnostics.Trace 进行基本跟踪,但由于复杂的原因,我必须通过 System.Diagnostics.TraceSource 对象(自 .NET 2.0 以来的新方法)激活跟踪,而不是使用 System .诊断.跟踪。我已经尝试了一切,但它只是不想使用 TraceSource 工作。我正在 ASP.NET 代码隐藏 (aspx.cs) 中执行跟踪

目前,根据 web.config 中的内容,它应该从以下代码跟踪到文件和页面:

TraceSource ts = new TraceSource("mysource", SourceLevels.All);
Trace.Write("Trace (old way)"); // this one works
ts.TraceInformation("Trace (new way)"); // this one doesn't work
ts.Flush();
ts.Close();

这是相关的 web.config 部分:

 <system.diagnostics>
       <trace autoflush="false">
            <listeners> <!-- these listeners activate the "old way" of tracing. -->
                 <add       name="pagelistener" />
                 <add       name="filelistener" />
            </listeners>
       </trace>

       <sources>
            <source name="mysource" switchName="myswitch">
                 <listeners>  <!-- these listeners activate the "new way" -->
                       <add name="pagelistener" />
                       <add name="filelistener" />
                 </listeners>
            </source>
       </sources>

                 initializeData="loplog.txt"
                 />
            <add
                 name="pagelistener"

                 />
       </sharedListeners>

       <switches>
            <!-- the sources above use this verbose switch -->
            <add name="myswitch" value="Verbose"/>
       </switches>

                            compilerOptions="/d:TRACE"
                            type="Microsoft.CSharp.CSharpCodeProvider, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
                            warningLevel="1"
                            />
       </compilers>
 </system.codedom>

 <system.web>
       <!-- this trace tag should be redundant because I added trace="true" to the aspx file,
                 but I put it in here anyway because this wasn't working. -->
       <trace writeToDiagnosticsTrace="true" enabled="true" pageOutput="true" requestLimit="50" localOnly="true"/>

I’m trying to set up .NET tracing. I’m able to get basic tracing to work via System.Diagnostics.Trace, but for complicated reasons I have to activate tracing via System.Diagnostics.TraceSource objects (the new way of doing it, since .NET 2.0) rather than using System.Diagnostics.Trace. I've tried everything but it just doesn't want to work using TraceSource. I am performing the tracing in an ASP.NET code-behind (aspx.cs)

Here are some related URLs:

Currently, based on what is in web.config, it should be tracing both to a file and to the page, from this code:

TraceSource ts = new TraceSource("mysource", SourceLevels.All);
Trace.Write("Trace (old way)"); // this one works
ts.TraceInformation("Trace (new way)"); // this one doesn't work
ts.Flush();
ts.Close();

Here’s the web.config sections that are relevant:

 <system.diagnostics>
       <trace autoflush="false">
            <listeners> <!-- these listeners activate the "old way" of tracing. -->
                 <add       name="pagelistener" />
                 <add       name="filelistener" />
            </listeners>
       </trace>

       <sources>
            <source name="mysource" switchName="myswitch">
                 <listeners>  <!-- these listeners activate the "new way" -->
                       <add name="pagelistener" />
                       <add name="filelistener" />
                 </listeners>
            </source>
       </sources>


       <sharedListeners> 
            <!-- these are the actual trace listeners -->
            <add
                  name="filelistener"
                 type="System.Diagnostics.TextWriterTraceListener"
                 initializeData="loplog.txt"
                 />
            <add
                 name="pagelistener"

                 />
       </sharedListeners>

       <switches>
            <!-- the sources above use this verbose switch -->
            <add name="myswitch" value="Verbose"/>

switchName="mySwitch" 更改为 switchValue="Verbose"。然后通过跟踪源输出所有跟踪。您可以更改 switchLevel 以增加/减少跟踪的详细程度。在您的示例中,您跟踪了一条信息消息,其中有详细信息、警告、错误、严重。将开关设置为警告,您将不会收到任何详细或信息消息。

change switchName="mySwitch" to switchValue="Verbose". This then outputs ALL traces via tracesource. You can change the switchLevel to increase / reduce the verbosity of the tracing. In your sample you have traced an information message, there is, verbose, information, warnings, error, critical. Set switch to warning and you won't get any verbose or information messages.
