I have read a lot of post on being able to read from a web.config file. I am trying to relate what I have found to a configuration.config file and have not had much success. Below is the layout of my configuration file.
<?xml version="1.0" encoding="utf-8"?>
<Configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SessionTimeout>20</SessionTimeout>
<ApplicationDirectory>C:\MyCompany\RunningFolder</ApplicationDirectory>
<Rounding>0.5</Rounding>
</Configuration>
I want to be able to do is pull the value but have not found a way to do this. Any assistance is greatly appreciated.
It sounds like you would benefit from using appsettings in your config file. Below is a link to msnd that explains them and how to read from them.
in your config file:
<appSettings>
<add key="ApplicationDirectory" value="C:\MyCompany\RunningFolder" />
<add key="Rounding" value="0.5" />
</appSettings>
In your code:
var ApplicationDirectory = ConfigurationManager.AppSettings["ApplicationDirectory"];

I have an MVC project and am trying to store my API keys in a separate config file which I will ignore when pushing the code to Git. According to MSDN I should be able to store them in an App.config like like so
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="APIKey" value="APIKeyValue" />
</appSettings>
</configuration>
I should then be able to read from the file by creating a method in a model
public class KeyTest
{
public string KeyTestCall()
{
string testkey = ConfigurationManager.AppSettings.Get("APIKey");
return testkey;
}
}
and then invoke the method in my controller to assign the value from my App.config file (just so I know I'm getting the value).
public void Testing()
{
KeyTest k = new KeyTest();
ViewBag.x = k;
}
At no point will the code break for a breakpoint, the build will succeed and I can't tell if I'm getting the value or not. Any help is much appreciated. Thanks!
For a web application such as an MVC app, it's a Web.config file, not an App.config
In addition to above (re: web.config vs app.config) if you want to remove "secrets" from source control, this is one way to do it:
In web.config
<?xml version="1.0" encoding="utf-8"?>
<cofiguration>
....
<appSettings file="AppKeys.config">
<add key="SomeOtherSettingThatHasNoSecrets" value="foo" />
...
Then in a separte AppKeys.config file (you can name this whatever.config, sample as named in the above), that you don't add to Git/source control:
<appSettings>
<add key="SomeSecretKey" value="the secret" />
...
Note that AppKeys.config doesn't have an XML declaration.
Hth.
Im having a hard time remembering how to do this, and most of the examples I'm seeing dont really cover my issue. I'm trying to read in the below XML file, so that if a user selects a Tool Type from a drop-down menu, the variables for said tool will populate a form on screen. I just have no clue how to collect all the elements/attributes for a specific tool.
<?xml version="1.0" encoding="UTF-8"?>
<Tool_menu>
<tool name="A">
<emails>
<email severity="Low">
<address>reg#test.com</address>
</email>
<email severity="High">
<address>notReg#test.com</address>
</email>
</emails>
<configuration_list>
<configuration>
<name>Confg1</name>
</configuration>
<configuration>
<name>Confg2</name>
</configuration>
<configuration>
<name>Confg3</name>
</configuration>
<configuration>
<name>Confg4</name>
</configuration>
</configuration_list>
</tool>
<tool name="B">
<emails>
<email severity="Low">
<address>reg#test.com</address>
</email>
<email severity="High">
<address>notReg#test.com</address>
</email>
</emails>
<configuration_list>
<configuration>
<name>n/a</name>
</configuration>
<configuration>
<name>n/a</name>
</configuration>
</configuration_list>
</tool>
<tool name="C">
<emails>
<email severity="Low">
<address>reg#test.com</address>
</email>
<email severity="High">
<address>notReg#test.com</address>
</email>
</emails>
<configuration_list>
<configuration>
<name>200Scope</name>
</configuration>
<configuration>
<name>300Scope</name>
</configuration>
<configuration>
<name>600Scope</name>
</configuration>
<configuration>
<name>900Scope</name>
</configuration>
</configuration_list>
</tool>
</Tool_menu>
what I'd want is for a user to select 'tool C' and see a list of configurations available on tool C, name of the tool, and a dropdown of options for who to email (low/high severity) that would be tool specific
**using .net 4.5
Access nodes using XPath.
Take a look at some tutorials here or here
In your case, accessing tools C can be achieved like this:
XmlDocument doc = new XmlDocument();
doc.Load(#"c:\temp\tools.xml");
var toolCemails = doc.SelectNodes("//tool[#name='C']/emails/email"); //two nodes with email tag
var toolCconfigs = doc.SelectNodes("//tool[#name='C']/configuration_list/configuration"); //four config nodes
You could take a look at this post on SO: LINQ to read XML
edit: also, in the comments below your question, #zx485 posted a link to another helpful SO post, here: Bind XML data to a Dropdownlist c#
That might help get you started. If not, please try to narrow your question to something more specific - preferably with some code that we can help you with.
As your question is written right now, it seems that you are asking us to do this for you rather than help you with a specific question.
Currently, in my web.config file I have
<configuration>
<general path="c:\abc\" />
</configuration>
I want to change c: to d: when I publish the release version.
How do I do this in a transform?
The <general> section is much much bigger so I don't want to rewrite then entire thing, just that one attribute. Can anyone help?
Update: I created the following web.release.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<system.web>
<compilation xdt:Transform="RemoveAttributes(debug)" />
</system.web>
<General dataFilePath="D:\Data" xdt:Transform="SetAttributes" xdt:Locator="Match(dataFilePath)" />
<AuditManagement auditPath="D:\Audit" xdt:Transform="SetAttributes" xdt:Locator="Match(auditPath)" />
</configuration>
This had no effect on the final web.config. It still shows "C:\" where I would want "D:\"
You can try adding these attributes to the Web.Release.config:
xdt:Transform="SetAttributes" xdt:Locator="Match(path)"
so your final result should be:
<configuration>
<general path="d:\abc\" xdt:Transform="SetAttributes" xdt:Locator="Match(path)"/>
</configuration>
I would recommend you to use transformation
First you have to create the different enviroments for debug or release, and if you want you can add more.
This tutorial is well explained and tested by me:
http://deanhume.com/home/blogpost/working-with-multiple-web-config-files/4100
And here is the official documentation:
https://msdn.microsoft.com/en-us/library/dd465326%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396
as it is explained in the previous your configuration for the web.config will be:
<configuration>
<general path="d:\abc\" xdt:Transform="SetAttributes" xdt:Locator="Match(path)"/>
</configuration>
and then you will have to define the correct path in the Debug and Realease configs, once it's finished you will run the app with one of the configurations you set.
I don't know why but i don't have AppSettings in my app.config.file.
If i add it, when i run my apps, appSetting is deleted, so i'm unable to read my data !
Here is my file :
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<add key="RepertoireEntree" value="E:\DEV\Autres\DevAgréga\Input\*.txt"/>
<add key="RepertoireSortie" value="E:\DEV\Autres\DevAgréga\Output\"/>
</configuration>
And in c# :
string RepertoireEntree = ConfigurationManager.AppSettings["RepertoireEntree"];
You have your app settings in a appSettings element, else it won't be recognized:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="RepertoireEntree" value="E:\DEV\Autres\DevAgréga\Input\*.txt"/>
<add key="RepertoireSortie" value="E:\DEV\Autres\DevAgréga\Output\"/>
</appSettings>
</configuration>
By the way, it is easier to use settings the usual way. You can do this by creating a settings file from your Project Settings > Settings tab.
Visual Studio will generate the XML elements in the app.config for you and you can reference your property like this:
string re = Properties.Settings.Default.RepertoireEntree;
You do not have your xml correct in the app.config file.
note the start and end tags for appSettings
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="RepertoireEntree" value="E:\DEV\Autres\DevAgréga\Input\*.txt"/>
<add key="RepertoireSortie" value="E:\DEV\Autres\DevAgréga\Output\"/>
</appSettings>
</configuration>
PS
While this is probably not an issue for you (but moreso for future readers)
Make sure you have this reference:
Namespace: System.Configuration
Assembly: System.Configuration (in System.Configuration.dll)
as noted on MSDN
I hope you can help me.
I'm supposed to add a new type of values to an AppSettings file (already existing with some values). Those values are a whole list of special folders so I thought the best way would be to have a new section for those folder values so that the file would look like this:for
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="usPath" value="folderName1" />
<add key="tcPath" value="folderName2" />
<add key="usGUID" value="folderID1" />
<add key="tcGUID" value="folderID2" />
</appSettings>
<updateFolders>
<add key="folderID3" value="folderName3">
<add key="folderID4" value="folderName4">
</updateFolders>
</configuration>
Reading and writing within the already existing appSettings-tag is no problem but I haven't find a way yet to modify the updateFolders section. I'm really new to using AppSettings in this way so I don't know too much about what's possible and what's not. In addition to that I think the AppSettings file might have been set up in a wrong way from the very beginning (it gets created by using a System.IO.File-Writer).
