My XML looks like this and the filename is web.config
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="configFile" value="IIS.config"/>
<add key="RialtoDomain" value="ASNC_AUDITORS"/>
</appSettings>
<system.serviceModel>
....
</system.serviceModel>
</configuration>
In the code when I read like this
String path = ConfigurationSettings.AppSettings["configFile"];
I am getting a null value. No exception is thrown. Is this the right way to do it?
This question is related to
c#
asp.net
web-config
Here's the easy way to get access to the web.config settings anywhere in your C# project.
Properties.Settings.Default
Use case:
litBodyText.Text = Properties.Settings.Default.BodyText;
litFootText.Text = Properties.Settings.Default.FooterText;
litHeadText.Text = Properties.Settings.Default.HeaderText;
Web.config file:
<applicationSettings>
<myWebSite.Properties.Settings>
<setting name="BodyText" serializeAs="String">
<value>
<h1>Hello World</h1>
<p>
Ipsum Lorem
</p>
</value>
</setting>
<setting name="HeaderText" serializeAs="String">
My header text
<value />
</setting>
<setting name="FooterText" serializeAs="String">
My footer text
<value />
</setting>
</myWebSite.Properties.Settings>
</applicationSettings>
No need for special routines - everything is right there already. I'm surprised that no one has this answer for the best way to read settings from your web.config file.
using System.Configuration;
/// <summary>
/// For read one setting
/// </summary>
/// <param name="key">Key correspondent a your setting</param>
/// <returns>Return the String contains the value to setting</returns>
public string ReadSetting(string key)
{
var appSettings = ConfigurationManager.AppSettings;
return appSettings[key] ?? string.Empty;
}
/// <summary>
/// Read all settings for output Dictionary<string,string>
/// </summary>
/// <returns>Return the Dictionary<string,string> contains all settings</returns>
public Dictionary<string, string> ReadAllSettings()
{
var result = new Dictionary<string, string>();
foreach (var key in ConfigurationManager.AppSettings.AllKeys)
result.Add(key, ConfigurationManager.AppSettings[key]);
return result;
}
Add namespace
using System.Configuration;
and in place of
ConfigurationSettings.AppSettings
you should use
ConfigurationManager.AppSettings
String path = ConfigurationManager.AppSettings["configFile"];
You should add System.configuration dll as reference and use System.Configuration.ConfigurationManager.AppSettings["configFile"].ToString
Don't forget to add using
statement at the beginning. Hope it will help.
ConfigurationManager.AppSettings["configFile"]
