I fail to read the appSettings from a config file. It is not located in the default location so when I tried using var aWSAccessKey = ConfigurationManager.AppSettings["AWSAccessKey"]; it didn't work.
Config file:
<appSettings>
<add key="AWSAccessKey" value="1" />
<add key="AWSSecretKey" value="2" />
<add key="AWSRegion" value="4" />
<add key="AWSAccountNumber" value="5" />
</appSettings>
Also tried with no success:
var fileMap = new ConfigurationFileMap("D:AWS\\CoreLocalSettings.config");
var configuration = ConfigurationManager.OpenMappedMachineConfiguration(fileMap);
var sectionGroup = configuration.GetSectionGroup("applicationSettings");
Finally it's working:
In the app.config file I read the outside config file data as below
<configuration>
<appSettings file="D:\AWS\CoreLocalSettings.config">
.......
</appSettings>
</configuration>
In the code base I am accessing same using the ConfigurationManager
var strAWSAccessKey = ConfigurationManager.AppSettings["AWSAccessKey"];
var web = System.Web.Configuration.WebConfigurationManager
.OpenWebConfiguration(#"D:\Employee\Hitesh\Projects\Web.config");
var appValue = web.AppSettings.Settings["SMTPServerPort"].Value;
var AWSAccessKey = ConfigurationManager.AppSettings["AWSAccessKey"];

I have this Q1.config file in my Console Application (.NET 4.5.2)
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="globalKey" value="globalValue" />
</appSettings>
<configSections>
<section name="validations" type="System.Configuration.NameValueSectionHandler" />
</configSections>
<validations>
<add key="validationKey" value="validationValue"/>
</validations>
</configuration>
I'm reading it like this
ExeConfigurationFileMap configFileMap = new ExeConfigurationFileMap { ExeConfigFilename = "Q1.config" };
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configFileMap, ConfigurationUserLevel.None);
ConfigurationSection validationSettings = config.GetSection("validations");
This works fine:
string globalValue = config.AppSettings.Settings["globalKey"].Value;
But how do I get my "validationKey"? I tried these but they don't work:
validationSettings["validationKey"]
validationSettings.Settings["validationKey"]
(config.GetSection("validations") as NameValueCollection)["validationKey"]
With the answer from #Karthik I ran into an issue... if I use ConfigurationManager.GetSection() I only get null. To get the section I have to use the config object returned by OpenMappedExeConfiguration. However, GetSection() in config isn't of type object as in ConfigurationManager, but DefaultSection from which I can't read the key value pairs, nor can I cast it to NameValueCollection. Browsing on the web I found this article with a solution that worked for me.
Basically extract the XML from the section and parse it manually with an XmlDoc.
public static NameValueCollection GetSectionSettings(string sectionToRead, string configPath)
{
if (!File.Exists(configPath)) { throw new ArgumentException($"File not found: {configPath}", nameof(configPath)); }
var fileMap = new ExeConfigurationFileMap() { ExeConfigFilename = configPath };
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
string settingsXml = config.GetSection(sectionToRead).SectionInformation.GetRawXml();
XmlDocument settingsXmlDoc = new XmlDocument();
settingsXmlDoc.Load(new StringReader(settingsXml));
NameValueSectionHandler handler = new NameValueSectionHandler();
return handler.Create(null, null, settingsXmlDoc.DocumentElement) as NameValueCollection;
}
Here you go
Your XML configuration
<configuration>
<configSections>
<section name="validations" type="System.Configuration.AppSettingsSection" />
</configSections>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
</startup>
<appSettings>
<add key="globalKey" value="globalValue" />
</appSettings>
<validations>
<add key="validationKey" value="validationValue"/>
</validations>
</configuration>
And you can get these values in C# using
ExeConfigurationFileMap configFileMap = new ExeConfigurationFileMap { ExeConfigFilename = "Q1.config" };
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configFileMap, ConfigurationUserLevel.None);
NameValueCollection validationSettings = (NameValueCollection)ConfigurationManager.GetSection("validations");
string globalValue = validationSettings[0];
I've used an index here validationSettings[0] to access the value. You can use your key to get the value
Thanks
I am trying something like
public string[] RegisterInApplicationConfig()
{
using (ServerManager serverManager = new ServerManager())
{
Configuration config = serverManager.GetApplicationHostConfiguration();
var section = config.GetSection("location/system.webServer/modules");
}
}
but error I am getting is -
The configuration section location/system.webServer/modules cannot be read because it is missing a section declaration.
I am referring post from to add HttpModule -
How do I register a HttpModule in the machine.config for IIS 7?
So Basically in ApplicationHostConfig I need to get to
<location path="" overrideMode="Allow">
<system.webServer>
<modules>
<add name="IsapiFilterModule" lockItem="true" />
So I found the solution after some hit & trials. Might help someone in future-
I needed to do GetCollection on "system.webServer/modules" section
Configuration config = serverManager.GetApplicationHostConfiguration();
var section = config.GetSection("system.webServer/modules", "");
var collection = section.GetCollection();
var element = collection.CreateElement();
element.Attributes["name"].Value = "MyHttpModule";
element.Attributes["type"].Value = MyHttpModule.XXXModule, MyHttpModule, Version=1.0.0.0, Culture=neutral, PublicKeyToken=bc88fbd2dc8888795";
collection.Add(element);
serverManager.CommitChanges();
here is my custom section in web.config. now i want read data by c#
<configuration>
<MailList>
<MailID id="test-uk#mysite.com" Value="UK" />
<MailID id="test-us#mysite.com" Value="US" />
<MailID id="test-ca#mysite.com" Value="CA" />
</databases>
</configuration>
suppose i want technique by which i can only read data based on value. if i supply UK as value then function will return uk mail id test-uk#mysite.com.
guide me how easily i can do this writing very minimum code. thanks
First of all your XML seems to be broken:
It must be something like that:
<configuration>
<MailList>
<MailID id="test-uk#mysite.com" Value="UK" />
<MailID id="test-us#mysite.com" Value="US" />
<MailID id="test-ca#mysite.com" Value="CA" />
</MailList>
</configuration>
This code should do what you want:
string country = "UK";
var result =
XDocument.Load("~/web.config")
.Element("configuration")
.Element("MailList")
.Elements("MailID")
.First(el => el.Attribute("Value").Value.Equals(country))
.Attribute("id")
.Value;
Console.WriteLine(result);
You could use the appsettings tag in your webconfig like:
<configuration>
<appSettings>
<add key="test-uk#mysite.com" value="UK" />
<add key="test-us#mysite.com" value="US" />
<add key="test-ca#mysite.com" value="CA" />
And after that you have your class:
public class WebConfigreader
{
public static string AppSettingsKey(string key)
{
if (WebConfigurationManager.AppSettings != null)
{
object xSetting = WebConfigurationManager.AppSettings[key];
if (xSetting != null)
{
return (string)xSetting;
}
}
return "";
}
}
And in your logic you are calling just:
String strUk = WebConfigreader.AppSettingsKey("test-uk#mysite.com");
I have a config file app.exe.config and appSettings section has something like this:
<configuration>
<appSettings configSource="app.file.config" />
</configuration>
app.file.config file has something like this:
<?xml version="1.0" encoding="utf-8" ?>
<appSettings>
<add key="var1" value="value 1" />
<add key="var2" value="value 2" />
<add key="var3" value="value 3" />
</appSettings>
I need to edit var1, var2 and var3 at runtime and I have code like this:
Configuration config = ConfigurationManager.OpenExeConfiguration("...path\app.exe);
config.AppSettings.SectionInformation.ConfigSource = "app.file.config";
config.AppSettings.Settings["var1"].Value = "value 11";
config.AppSettings.Settings["var2"].Value = "value 22";
config.AppSettings.Settings["var3"].Value = "value 33";
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");
When I run config.Save.... the file app.file.config has a appSettings node with an attribute "file". This attribute has the value to app.file.config
<appSettings file="app.file.config">
<add key="var1" value="value 1" />
<add key="var2" value="value 2" />
<add key="var3" value="value 3" />
</appSettings>
Now, if I try to load the config file, I have an exception with message "Unrecognized attribute 'file'. Note that attribute names are case-sensitive." in app.file.config.
If I delete the file attribute manually, the configuration file is loaded properly.
Any ideas?
How can avoid to write file attribute when I save config files.
Thanks
using an external config file is transparent for the application,
this part is o.k
</configuration>
<appSettings configSource="app.file.config" />
</configuration>
and also this:
<?xml version="1.0" encoding="utf-8" ?>
<appSettings>
<add key="var1" value="value 1" />
<add key="var2" value="value 2" />
<add key="var3" value="value 3" />
</appSettings>
change your code to be like this:
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
config.AppSettings.Settings["var1"].Value = "value 11";
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");
referring an external configuration file is transparent to the application,
so you don't have to call it directly. you can use the default appSetting section in the configuration manager.
Good luck
A more complete answer to prevent confusion:
Setup:
Commandline project called 'app'
app.exe.config file, App.config:
<appSettings file="App.Settings.config"></appSettings>
App.Settings.config file with 'Copy to Output Directory'= 'Copy Always'
<?xml version="1.0" encoding="utf-8"?>
<appSettings>
<add key="test" value="OVERRIDDEN"/>
</appSettings>
Program.cs:
static void Main(string[] args)
{
try
{
Console.WriteLine("Local Config sections");
var exepath = (new Uri(System.Reflection.Assembly.GetExecutingAssembly().CodeBase)).LocalPath;
Configuration config = ConfigurationManager.OpenExeConfiguration(exepath);
config.AppSettings.SectionInformation.ConfigSource = "App.Settings.config";
Console.WriteLine("BEFORE[test]=" + config.AppSettings.Settings["test"].Value);
Console.WriteLine($"BEFORE[testExternalOnly]={config.AppSettings.Settings["testExternalOnly"]?.Value}");
//to avoid: Error CS0266
//Explicitly cast 'System.Configuration.AppSettingsSection'
AppSettingsSection myAppSettings = (AppSettingsSection)config.GetSection("appSettings");
myAppSettings.Settings["test"].Value = "NEW";
if (!myAppSettings.Settings.AllKeys.Contains("testExternalOnly"))
myAppSettings.Settings.Add("testExternalOnly", "NEWEXTERNAL");
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");
//Read updated config
Console.WriteLine("AFTER[test]=" + config.AppSettings.Settings["test"].Value);
Console.WriteLine("AFTER[testExternalOnly]=" + config.AppSettings.Settings["testExternalOnly"].Value);
Console.WriteLine("AFTER CONFIG EXTERNAL FILE: " + System.IO.File.ReadAllText("App.Settings.config"));
Console.WriteLine("AFTER CONFIG FILE: " + System.IO.File.ReadAllText(System.AppDomain.CurrentDomain.FriendlyName + ".config"));
//Shut current config
config = null;
//Open config
config = ConfigurationManager.OpenExeConfiguration(exepath);
config.AppSettings.SectionInformation.ConfigSource = "App.Settings.config";
Console.WriteLine("AFTER[test]=" + config.AppSettings.Settings["test"].Value);
Console.WriteLine("AFTER[testExternalOnly]=" + config.AppSettings.Settings["testExternalOnly"].Value);
Console.WriteLine("AFTER CONFIG EXTERNAL FILE: " + System.IO.File.ReadAllText("App.Settings.config"));
Console.WriteLine("AFTER CONFIG FILE: " + System.IO.File.ReadAllText(System.AppDomain.CurrentDomain.FriendlyName + ".config"));
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
Console.WriteLine("press the ENTER key to end");
Console.ReadLine();
}
This will result in App.Settings.config file updated to be on the filesystem as:
<?xml version="1.0" encoding="utf-8"?>
<appSettings>
<add key="test" value="NEW" />
<add key="testExternalOnly" value="NEWEXTERNAL" />
</appSettings>
Finally, I have found a solution.
The solution is to declare the config file as this:
<appSettings configSource="app.file.config">
<add key="var1" value="value 1" />
<add key="var2" value="value 2" />
<add key="var3" value="value 3" />
</appSettings>
And from code
Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
AppSettingsSection myAppSettings = config.GetSection("appSettings")
myAppSettings.Settings["var1"].Value = "value 11";
config.Save(ConfigurationSaveMode.Modified);
Note that I use
GetSection("appSettings")
instead of
config.AppSettings.Settings
Thanks to all that help people in StackOverflow.
I've got the following section in my web.config:
<system.webServer>
<staticContent>
<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="0.00:00:30" />
<remove fileExtension=".ogv" />
<mimeMap fileExtension=".ogv" mimeType="video/ogg" />
<remove fileExtension=".webm" />
<mimeMap fileExtension=".webm" mimeType="video/webm" />
<!-- and a bunch more... -->
</staticContent>
<!-- ... -->
</system.webServer>
Here's what I'm trying to do in psuedo-code:
var ext = ".ogg";
var staticContentElements = GetWebConfig().GetSection("system.webServer/staticContent").ChildElements;
var mimeMap = staticContentElements.Where(c =>
c.GetAttributeValue("fileExtension") != null &&
c.GetAttributeValue("fileExtension").ToString() == ext
).Single();
var mimeType = mimeMap.GetAttributeValue("mimeType").ToString();
Basically, I need to search the mimeMaps by a fileExtension and get their mimeType.
You need to create a custom configuration section to get that information.
George Stocker's answer led me to a Google search for["staticContent" custom configuration section] which brought me to an iis.net article titled Adding Static Content MIME Mappings <mimeMap>.
The article led me to come up with:
using (var serverManager = new ServerManager())
{
var siteName = HostingEnvironment.ApplicationHost.GetSiteName();
var config = serverManager.GetWebConfiguration(siteName);
var staticContentSection = config.GetSection("system.webServer/staticContent");
var staticContentCollection = staticContentSection.GetCollection();
var mimeMap = staticContentCollection.Where(c =>
c.GetAttributeValue("fileExtension") != null &&
c.GetAttributeValue("fileExtension").ToString() == ext
).Single();
var mimeType = mimeMap.GetAttributeValue("mimeType").ToString();
contentType = mimeType.Split(';')[0];
}
Which works perfectly for me. I just need to add some null checks here and there and it should be good to go.
