The Refernce.cs file that is generated by the Visual Studio indicates that the URL of the webservice will be retrieved from the settings:
this.Url = global::ConsoleApplication1.Properties.
Settings.Default.ConsoleApplication1_net_webservicex_www_BarCode;
I believe that John Saunders gave you a wonderful suggestion in his comment. You need a SettingsProvider class which:
...defines the mechanism for storing configuration data used in the
application settings architecture. The .NET Framework contains a
single default settings provider, LocalFileSettingsProvider, which
stores configuration data to the local file system. However, you can
create alternate storage mechanisms by deriving from the abstract
SettingsProvider class. The provider that a wrapper class uses is
determined by decorating the wrapper class with the
SettingsProviderAttribute. If this attribute is not provided, the
default, LocalFileSettingsProvider, is used.
I don't know how much you have progressed following this approach, but it should go pretty straighforward:
Create the SettingsProvider class:
namespace MySettings.Providers
{
Dictionary<string, object> _mySettings;
class MySettingsProvider : SettingsProvider
{
// Implement the constructor, override Name, Initialize,
// ApplicationName, SetPropertyValues and GetPropertyValues (see step 3 below)
//
// In the constructor, you probably might want to initialize the _mySettings
// dictionary and load the custom configuration into it.
// Probably you don't want make calls to the database each time
// you want to read a setting's value
}
}
Extend the class definition for the project's YourProjectName.Properties.Settings partial class and decorate it with the SettingsProviderAttribute:
[System.Configuration.SettingsProvider(typeof(MySettings.Providers.MySettingsProvider))]
internal sealed partial class Settings
{
//
}
In the overridden GetPropertyValues method, you have to get the mapped value from the _mySettings dictionary:
public override SettingsPropertyValueCollection GetPropertyValues(
SettingsContext context,
SettingsPropertyCollection collection)
{
var spvc = new SettingsPropertyValueCollection();
foreach (SettingsProperty item in collection)
{
var sp = new SettingsProperty(item);
var spv = new SettingsPropertyValue(item);
spv.SerializedValue = _mySettings[item.Name];
spv.PropertyValue = _mySettings[item.Name];
spvc.Add(spv);
}
return spvc;
}
As you can see in the code, in order to do that, you need to know the setting name as it was added in the app.config and the Settings.settings when you have added the reference to the web service (ConsoleApplication1_net_webservicex_www_BarCode):
<applicationSettings>
<ConsoleApplication30.Properties.Settings>
<setting name="ConsoleApplication1_net_webservicex_www_BarCode"
serializeAs="String">
<value>http://www.webservicex.net/genericbarcode.asmx</value>
</setting>
</ConsoleApplication30.Properties.Settings>
</applicationSettings>
This is a very simple example, but you might use a more complex object to store the configuration information in conjunction with other properties available in the context such as item.Attributes or context in order to get the proper configuration value.
