从.NET程序集加载项目设置 [英] Load Project Settings from .NET Assembly

问题描述

我有一个.NET C＃2008赢表单解决方案多个项目。其中的一些项目有在其中定义设置（通过项​​目属性，设置UI部分 - 而不是一个配置文件）。我试图建立自己的应用程序的调试部分（隐藏远离用户），将然后显示了这些设置是当前设置为。我有以下code，获取所有的组件：

I have multiple projects in a .NET C# 2008 Win Forms Solution. Some of these projects have settings that are defined in them (through the project properties, settings UI portion - not a config file). I am attempting to build a debug portion of my application (hidden away from the users) that would then display what these settings are currently set at. I have the below code that gets all of the assemblies:

AssemblyName[] assemComponents = Assembly.GetExecutingAssembly().GetReferencedAssemblies();

foreach (AssemblyName assemName in assemComponents)
{
     ListViewItem item = listComponents.Items.Add(assemName.Name);
     item.SubItems.Add(assemName.Version.ToString());                                
}

目前的code这个块只需把程序集名称的列表以及它们在控制版本。不过，我想知道，如果使用这些组件对象（或任何其他人对这个问题）我可以取回已设置的项目设置。

Currently this block of code just puts the list of assembly names and their version in a control. However, I would like to know if using these Assembly objects (or any others for that matter) I can retrieve the project settings that have been set.

感谢大家的帮助，请让我知道，如果我可以提供更多的细节。

Thank you all for your help and please let me know if I can provide additional detail.

推荐答案

当您添加项目到设置设计时，Visual Studio生成一个类的读/写这些设置到文件;它还包括用于访问该类保存的默认值实例的静态默认属性。 （请参阅您的项目Settings.Designer.cs）。

When you add items to the Settings Designer, Visual Studio generates a class for reading/writing those settings to a file; it also includes a static Default property for accessing an instance of this class that holds the default values. (See Settings.Designer.cs in your project).

您可以找到这些类和反思检查他们：

You can locate these classes and inspect them with reflection:

foreach ( AssemblyName assemName in assemComponents )
{
    foreach ( var type in Assembly.Load( assem ).GetTypes() )
    {
        // look for classes that derive from SettingsBase named "Settings"
        if ( type.Name == "Settings" && typeof( SettingsBase ).IsAssignableFrom( type ) )
        {
            // get the value of the static Default property
            var defaults = (SettingsBase)type.GetProperty( "Default" ).GetValue( null, null );

            // walk the property list and get the value from the Default instance
            foreach ( SettingsProperty prop in defaults.Properties )
            {
                Debug.WriteLine( string.Format( "{0}: {1}", prop.Name, defaults[ prop.Name ] ) );
            }
        }
    }
}
