I receive the following error from a Windows Service application
System.Net.WebException = {"An exception occurred during a WebClient request."}
-2146233079
InnerException = {"Configuration system failed to initialize"}
The same code on a Console application works fine.
The Service file has not setup Security on "Local Service" (in my test environment)
Could you point me out what could cause the error and how to solve it?
Try
Using client As New Net.WebClient
Dim reqparm As New Specialized.NameValueCollection
reqparm.Add("DeviceId", deviceId)
reqparm.Add("StatusCode", statusCode)
reqparm.Add("Type", "printer")
reqparm.Add("Message", msg)
Dim responsebytes = client.UploadValues("http://xxx.xxx.com/api/notification", "POST", reqparm)
Dim responsebody = (New Text.UTF8Encoding).GetString(responsebytes)
End Using
Catch ex As Exception
'do nothing
End Try
my App.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

</configSections>
<app>
<add key="version" value="0.0.1"/>
</app>

The problem was in the App.config file. This the correct version, only one instance of <configSections> and should be the first element after <configuration>.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="app" type="System.Configuration.NameValueSectionHandler" />

I have created a basic feature file and trying to execute my first program. I have installed all mandatory packages through NuGet.
Error received :

my app.config looks like:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
</startup>
<configSections>
<sectionGroup name="NUnit">
<section name="TestRunner" type="System.Configuration.NameValueSectionHandler" />
</sectionGroup>

</configSections>
<specFlow>
<language feature="en-US" />
<unitTestProvider name="MSTest" />
</specFlow>
</configuration>
The unit test providers are not configured anymore in the app.config with SpecFlow 3. You have to use the appropriate NuGet package. Doc link: https://docs.specflow.org/projects/specflow/en/latest/Guides/UpgradeSpecFlow2To3.html#changes-to-how-unit-test-providers-are-configured
In your case, you have to add the SpecFlow.NUnit package to your project and adjust your app.config to
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
</startup>
<configSections>
<sectionGroup name="NUnit">
<section name="TestRunner" type="System.Configuration.NameValueSectionHandler" />
</sectionGroup>
<section name="specFlow" type="TechTalk.SpecFlow.Configuration.ConfigurationSectionHandler, TechTalk.SpecFlow" />
</configSections>
<specFlow>
<language feature="en-US" />
</specFlow>
</configuration>
The list of the correct NuGet package depending on your unit test runner is: https://docs.specflow.org/projects/specflow/en/latest/Installation/Unit-Test-Providers.html
Full disclosure: I am a developer and maintainer of SpecFlow and SpecFlow+
Here is my AppConfig File
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>
</startup>
<connectionStrings>
<add name="Connection" connectionString="(local)\SQLexpress"/>
<add name="MainPrinter" connectionString=""/>
</connectionStrings>
</configuration>
And I want to change MainPrinter's Name
Here is what i'm trying to do:
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings["MainPrinter"].Value = "Epson";
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("connectionStrings");
But i dont take any result
I want to create a simple section without writing any class by myself, I have read other posts and tried building my own section but it throws an exception of System.InvalidCastException when I try to get my section. Could anyone tell me how I can solve it? thanks!
Exception message:
An unhandled exception of type 'System.InvalidCastException' occurred in HttpServer.exe
Additional information: Unable to cast object of type 'System.Configuration.KeyValueInternalCollection' to type 'System.Configuration.AppSettingsSection'.
App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="extensions" type="System.Configuration.AppSettingsSection" />
</configSections>
<extensions>
<add key=".gif" value="image/gif"/>
<add key=".png" value="image/png"/>
<add key=".jpg" value="image/jpeg"/>
</extensions>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
C# code:
AppSettingsSection section = (AppSettingsSection)ConfigurationManager.GetSection("extensions");
Console.WriteLine(section.Settings[".gif"].Value.ToString());
Change the System.Configuration.AppSettingsSection to System.Configuration.NameValueSectionHandler and get the value by
System.Collections.Specialized.NameValueCollection
?xml version="1.0" encoding="utf-8" ?>
****<configuration>****
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
The above is one part of encoding in my program, which gives a error. Error is in the second line, which shows me something like a blue lined,
configuration element is not declared
For what reason it happens like this?
Error due to the missing '<' at start element
Change it to :
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
It gives an error on the second line? That's certainly odd, considering the missing '<' at the start of the first line. But the asterisks around the second line also clearly don't belong there.
How did you get this file? Where does it come from?
And have you tried this?
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
Because that's what it probably should be.
It gives error because you are missing '<' at start of the file
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<Connectionstring>
<add key="questionpaper" value="server=localhost;database=Question_info;
UID=root;password=SATISH;"/>
</Connectionstring>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
this is my app.config but unable to connect to MySql server
so please tell me how to deal with this problem
How to write mysql connection string in app.config in c#
You need to pluralize the connectionStrings tag.
<connectionStrings>
<add name"ConnectionStringName" connectionString="Data Source=serverName;Initial Catalog=databaseName;Intergated Security=SSPI;Application Name=My.Application.Name" providerName="System.Data.SqlClient" />
</connectionStrings>
The add key/value tag is also the format to use for appSettings, not connectionStrings.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="questionpaper" connectionString="SERVER=localhost; DATABASE=Question_info; UID=root; PASSWORD=SATISH" />
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
</configuration>
