configurationmanager

If an assembly contains an app.config file, ConfigurationManager will load it as long as it is in the same directory as the NUnit project that is executing through NUnit-Gui. To illustrate consider the following folder structure. + TestFolder testProject.nunit + AssemblyAFolder assemblyA.dll assemblyA.dll.config + AssemblyBFolder assemblyB.dll assemblyB.dll.config Both AssemblyA and AssemblyB exercise code that calls into ConfigurationManager . If I run these test assemblies independently in NUnit-Gui, ConfigurationManager will correctly resolve the local configuration files. However, if I

I would like to override the use of the standard app.config by passing a command line parameter. How do I change the default application configuration file so that when I access ConfigurationManager.AppSettings I am accessing the config file specified on the command line? Edit: It turns out that the correct way to load a config file that is different than the name of the EXE plus .config is to use OpenMappedExeConfiguration. E.g. ExeConfigurationFileMap configFile = new ExeConfigurationFileMap(); configFile.ExeConfigFilename = Path.Combine(Environment.CurrentDirectory, "Shell2.exe.config");

I've got a reference to System.Configuration - and ConfigurationSettings is found no problem - but the type or namespace ' ConfigurationManager ' could not be found!? I've read around - and it looks like it should belong to the same namespace as the ConfigurationSettings class. EDIT: Please take note - I've clearly said I have added a reference to System.Configuration . There's been 4 comments already about this. ConfigurationManager is a part of the System.Configuration after .Net 2.0. Add a reference to the System.Configuration dll. Try using System.Configuration.ConfigurationManager. You

When i run a simple test on connection to DB check i receive an error in NUnit: [Test] public void TestConn() { string connectionString = ConfigurationManager.ConnectionStrings["FertigungRead"].ConnectionString; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); Assert.AreEqual(ConnectionState.Open, connection.State); connection.Close(); } System.NullReferenceException : Object reference not set to an instance of an object. on line : connectionString = ConfigurationManager.ConnectionStrings["FertigungRead"].ConnectionString; Can i use ConfigurationManager in

We know that IIS caches ConfigurationManager.AppSettings so it reads the disk only once until the web.config is changed. This is done for performance purposes. Someone at: http://forums.asp.net/p/1080926/1598469.aspx#1598469 stated that .NET Framework doesn't do the same for app.config, but it reads from the disk for every request. But I find it hard to believe, 'cause it would be slower. Please tell me that he is wrong or I'll have to fix every Console/Windows Forms/Windows Services I wrote. Update I regret that I misinterpreted what people said in the linked forum above. A quick test seems

I had some trouble on a test server with an ASP.NET website. I goofed, and had the home directory of the Default Web Site pointed to the wrong place. When I tried: ConfigurationManager.ConnectionStrings["connectionString"]; it returned null, but using System.Web.Configuration; /* ... */ var rootWebConfig = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath); WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath); rootWebConfig.ConnectionStrings.ConnectionStrings["connectionString"].ConnectionString;` returned the correct connection string. What are all the

I'm just wondering how the ConfigurationManager.AppSettings[Key] works? Does it read from the physical file each time I need a key? If so, should I be reading all the app settings of my web.config in a cache and then read from it? Or ASP.NET or IIS loads the web.config file at application_startup and only once. How to verify whether the physical file is accessed by each read? If I change the web.config, IIS restarts my application so can't verify it that way. Thanks, dash It gets cached, on first access of a property, so it does not read from the physical file each time you ask for a value.
