Hi guys,
I'm trying to create custom settings provider and it doesn't go well. I've already spent five hours on it with no luck :( In few words my goal is to store settings alongside with the binary instead of having per-user settings that will be stored
in local user's folder. I'm using VS2010 on Win7 x64 if that matters. Code of my class is very simple. I'm testing it in console application (.Net 3.5). It looks something like this:
public class MyProvider : SettingsProvider
{
public override SettingsPropertyValueCollection GetPropertyValues(SettingsContext context, SettingsPropertyCollection collection)
{
var result = new SettingsPropertyValueCollection();
foreach (SettingsProperty property in collection)
{
Debug.WriteLine(property.ToString());
}
return result;
}
public override void SetPropertyValues(SettingsContext context, SettingsPropertyValueCollection collection)
{
Debug.WriteLine(collection.Count);
}
public override string ApplicationName
{
get
{
return "MyApp";
}
set { }
}
}
I have only one setting field. Here is content of .setting file
<?xml version='1.0' encoding='utf-8'?>
<SettingsFile xmlns="http://schemas.microsoft.com/VisualStudio/2004/01/settings" CurrentProfile="(Default)" GeneratedClassNamespace="console.Properties" GeneratedClassName="Settings">
<Profiles />
<Settings>
<Setting Name="Test" Provider="console.MyConfig" Type="System.String" Scope="User">
<Value Profile="(Default)" />
</Setting>
</Settings>
</SettingsFile>
and finally here is code that is manipulating with settings
Settings.Default.Test = "aaa";
Settings.Default.Save();
I'm expecting two things to happen here - call to MyProvider.GetPropertyValues() and then MyProvider.SetPropertyValues(). Unfortunately it doesn't happen because SettingsPropertyNotFoundException ("Value cannot be null. Parameter
name: name") is thrown in Settings.Designer.cs. Source code is bellow. I marked line where exception happens:
namespace console.Properties {
[global::System.Runtime.CompilerServices.CompilerGeneratedAttribute()]
[global::System.CodeDom.Compiler.GeneratedCodeAttribute("Microsoft.VisualStudio.Editors.SettingsDesigner.SettingsSingleFileGenerator", "10.0.0.0")]
internal sealed partial class Settings : global::System.Configuration.ApplicationSettingsBase {
private static Settings defaultInstance = ((Settings)(global::System.Configuration.ApplicationSettingsBase.Synchronized(new Settings())));
public static Settings Default {
get {
return defaultInstance;
}
}
[global::System.Configuration.UserScopedSettingAttribute()]
[global::System.Configuration.SettingsProviderAttribute(typeof(console.MyProvider))]
[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
[global::System.Configuration.DefaultSettingValueAttribute("")]
public string Test {
get {
return ((string)(this["Test"]));
}
set {
this["Test"] = value; // EXCEPTION IS THROWN HERE
}
}
}
}
No calls to MyPrivader were made at all.
Any ideas what I'm doing wrong?
