聊聊程式

AppSettings 是很常放一些網站變數的地方 但每次 都要用 ConfigurationManager.AppSettings["ModuleTitle"]
去拿資料 打字起來就嫌長 所以 可以放到 Static class 這樣還可以有提示 跟 快取的效果 程式碼是參考文章內提供的

public class AppConfig
{
private static string _moduleTitle;
private static bool? _bundlingActive;
 
public static string ModuleTitle
{
    get
    {
        if (string.IsNullOrEmpty(_moduleTitle))
            _moduleTitle = ConfigurationManager.AppSettings["ModuleTitle"];
        return _moduleTitle;
    }
}
 
public static bool BundlingActive
{
    get
    {
        if (!_bundlingActive.HasValue)
            _bundlingActive = ConfigurationManager.AppSettings["BundlingActive"] == "1";
        return _bundlingActive.Value;
    }
}
}

Testing codes with ConfigurationManager.AppSettings

using System.Collections.Specialized;
using System.Configuration;

public interface IAppSettings
{
    string this[string key] { get; }
}

public class AppSettingsWrapper : IAppSettings
{
    private readonly NameValueCollection appSettings;

    public AppSettingsWrapper()
    {
        this.appSettings = ConfigurationManager.AppSettings;
    }
    public string this[string key]
    {
        get
        {
            return this.appSettings[key];
        }
    }
}
