為了不使自己寫的代碼看著臃腫，有些固定的值抽取出來，放入配置文件里，這樣，不失為一種好的編碼習(xí)慣。這里介紹兩種不同的文件格式：
一、AppSetting.config(.config格式)
1、首先，配置一下
1 <?xml version="1.0" encoding="utf-8"?>2 <appSettings>3 <!--糾錯(cuò)信息處理狀態(tài)-->4 <add key="CorrectState" value="已處理:0;未處理:1" />5 <!--調(diào)用接口 地址配制-->6 <add key="Api_BaseUrl" value="http://172.16.16.68:8321/"/>7 </appSettings>
2、讀取唯一值
1 /// <summary> 2 /// 通過key,獲取appSetting的值 3 /// </summary> 4 /// <param name="key">key</param> 5 /// <returns>value</returns> 6 public static string GetWebConfigValueByKey(string key) 7 { 8 string value = string.Empty; 9 Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);10 AppSettingsSection appSetting = (AppSettingsSection)config.GetSection("appSettings");11 if (appSetting.Settings[key] != null)//如果不存在此節(jié)點(diǎn)，則添加 12 {13 value = appSetting.Settings[key].Value;14 }15 config = null;16 return value;17 }
3、讀取多個(gè)值
1 /// <summary> 2 /// 如果值為 "已審核:1;待審核:0" 形式 ,可通過該函數(shù)獲取該appsetting值的指定value對應(yīng)的key 3 /// </summary> 4 /// <param name="appSettingName"></param> 5 /// <returns></returns> 6 public static string GetKVofKey(string appSettingName, string value) 7 { 8 List<KV> l = new List<KV>(); 9 string str = GetWebConfigValueByKey(appSettingName);10 string[] arr = str.Split(';');11 string rs = "";12 if (arr.Length > 0)13 {14 int length = arr.Length;15 for (int i = 0; i < length; i++)16 {17 if (arr[i].Split(':')[1] == value)18 {19 rs = arr[i].Split(':')[0];20 }21 }22 }23 return rs;24 }
所用類
1 1 public class KV2 2 {3 3 public string k;4 4 public string v;5 5 }
二、Api.ini
1、配置文件
1 #微信支付2 [WeiXinPay]3 appId=wx1***14 partnerid=1***15 appSecret=6***5 6 key=N**C
2、ApiHelper.cs（類）
1 public class ApiHelper 2 { 3 /// <summary> 4 /// 配置文件虛擬路徑 5 /// </summary> 6 private const string ConfigFile = "~/Config/Api.ini"; 7 /// <summary> 8 /// 獲取配置節(jié) 9 /// </summary>10 /// <typeparam name="T">節(jié)點(diǎn)類型（引用類型）</typeparam>11 /// <param name="section">節(jié)點(diǎn)名稱</param>12 /// <returns></returns>13 public static T GetConfigureSection<T>(string section)14 where T:class15 {16 SharpConfig.Configuration configuration = GetIniConfiguration();17 return configuration[section].CreateObject<T>();18 }19 public static string GetPath(string path)20 {21 if (HttpContext.Current !=null)22 {23 return HttpContext.Current.Server.MapPath(path);24 }25 path = path.Replace("/","\\");26 if (path.StartsWith("\\"))27 {28 path = path.Substring(path.IndexOf('\\', 1)).TrimStart('\\');29 }30 return Path.Combine(AppDomain.CurrentDomain.BaseDirectory,path);31 }32 /// <summary>33 /// 34 /// </summary>35 /// <returns></returns>36 public static SharpConfig.Configuration GetIniConfiguration() 37 {38 const string SYSTEM_API_CONFIG = "SYSTEM_API_CONFIG";//配置Key39 //如果緩存存在，則提取緩存數(shù)據(jù)40 if (RuntimeCacheHelper.IsExists(SYSTEM_API_CONFIG))41 {42 return RuntimeCacheHelper.Get<SharpConfig.Configuration>(SYSTEM_API_CONFIG);43 }44 //從配置文件中加載，并緩存配置45 else46 {47 SharpConfig.Configuration configuration = null;48 String strConfigAbsolutePath = GetPath(ConfigFile);49 configuration = SharpConfig.Configuration.LoadFromFile(strConfigAbsolutePath);50 //緩存對象51 RuntimeCacheHelper.Save(SYSTEM_API_CONFIG,configuration,strConfigAbsolutePath,new TimeSpan(365,0,0,0,0));52 return configuration;53 }54 }55 }
緩存類
1 public class RuntimeCacheHelper 2 { 3 public static bool IsExists(string Name) 4 { 5 return (HttpRuntime.Cache[Name] != null); 6 } 7 public static T Get<T>(string Name) 8 { 9 if (null != HttpRuntime.Cache[Name]) { return (T)HttpRuntime.Cache[Name]; }10 return default(T);11 }12 13 public static void Save(string Name, object Value, string FileName, TimeSpan expirese)14 {15 var dependency = new CacheDependency(FileName);16 Save(Name,17 Value,18 dependency,19 expirese);20 }21 22 public static void Save(string Name, object Value)23 {24 HttpRuntime.Cache.Insert(Name, Value);25 }26 27 public static void Save(string Name, object Value, CacheDependency Dependency, TimeSpan expirese)28 {29 HttpRuntime.Cache.Insert(Name,30 Value,31 Dependency,32 (DateTime.Now + expirese),33 System.Web.Caching.Cache.NoSlidingExpiration);34 }35 }
3、請求上下文（HttpContextExtension）類
1 public static class HttpContextExtension 2 { 3 /// <summary> 4 /// 請求上下文 5 /// </summary> 6 /// <param name="context"></param> 7 /// <returns></returns> 8 public static WeiXinPayConfig GetWeiXinPayConfig(this HttpContextBase context) 9 {10 return ApiHelper.GetConfigureSection<WeiXinPayConfig>("WeiXinPay");11 }12 }
4、獲取值
1 /// <summary> 2 /// 3 /// </summary> 4 private Models.WeiXinPayConfig wxApiConfig { get; set; } 5 /// <summary> 6 /// 7 /// </summary> 8 /// <returns></returns> 9 public ActionResult GetConfig()10 {11 12 wxApiConfig = HttpContext.GetWeiXinPayConfig();13 14 return View();15 }
