.NET tracing in PowerShell without creating .config file

阅读更多关于 .NET tracing in PowerShell without creating .config file

I know I can enable .NET tracing by adding <system.diagnostics> element to App config ( powershell.exe.config ) in PowerShell installation folder. This is covered in System.Net tracing in Powershell . In fact, I too want to log System.Net tracing source (e.g. FtpWebRequest ) . But is there a way to enable tracing locally? Like in the code itself? Or possibly using some command-line switch? Or can I at least have the App config file in a local folder, not to have to modify the system-wide settings?

问题 I'd think this would be simple, but I can't find an answer. I'm using remoting and I want to store the RemotingConfiguration in the app.config. When I call RemotingConfiguration.Configure I have to supply the filename where the remoting information resides. So... I need to know the name of the current configuration file. Currently I'm using this: System.Reflection.Assembly.GetExecutingAssembly().Location + ".config" But this only works for windows applications, not for web applications. Isn't

.NET own configuration file

阅读更多关于 .NET own configuration file

Is there any way that I could specify at runtime the configuration file I would like to use (other than App.config)? For example I would like to read a first argument from a command line that will be a path to the application's config and I would like my application to refer to it when I use ConfigurationManager.AppSettings (It's probably impossible but still it's worth asking). I did find this piece of code: System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); config.AppSettings.File = myRuntimeConfigFilePath; config.Save

I'm having an issue with a .NET 3.5 library I'm developing to send emails. I put the system.net configuration into app.config : <system.net> <mailSettings> <smtp from="mail@domain.com"> <network host="myserver.com" port="25" defaultCredentials="true" /> </smtp> </mailSettings> </system.net> And I instantiate the SmtpClient without params: SmtpClient client = new SmtpClient(); But the configuration is not read (I'm trying to test the library with NUnit) and I get a System.InvalidOperationException , because the configuration is not read and thus the host is null.
