如何以编程方式启用WCF跟踪？

Question

有没有办法在不更改web.config的情况下为特定端点启用/禁用WCF跟踪/日志记录？

Answer 1

You first need to access the trace object by name, as its defined in the .config file. For example:

TraceSource ts = new TraceSource("System.ServiceModel");

Then you can set the filter level to all, none or anything in between:

ts.Switch.Level = SourceLevels.Off;   // nothing
ts.Switch.Level = SourceLevels.All;   // everything
ts.Switch.Level = SourceLevels.Warning;   //warning or higher

BTW - the TraceSource class is in the System.Diagnostics namespace, so don't forget the appropriate using statement.
