C# winform 读取app.config

修改app.config文件在appSettings节点中加入CKName

 "1.0" encoding="utf-8"?>
 
      
        "Conn" connectionString="Data Source=127.0.0.1;Initial Catalog=test;Persist Security Info=True;User ID=test;Password=test;Min Pool Size=1;Max Pool Size=10;Connect Timeout=30;Load Balance Timeout=60;ConnectRetryCount=10" providerName="System.Data.SqlClient" />
    
   
    "CKName" value=" " />
  
  
  需要引用 using System.Configuration;
  如果还有问题，需要在解决方案管理器中找到“引用”，点击右键“添加引用”找到System.Configuration即可。
  设置CKName方法
        private void SetCKName(string value) { 
        Configuration cfa = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
            cfa.AppSettings.Settings["CKName"].Value = value;
            cfa.Save();      System.Configuration.ConfigurationManager.RefreshSection("appSettings");
        }
取得CKName方法
        private string GetCKName()
        {
            String CKName = ConfigurationManager.AppSettings["CKName"];
            return CKName; 
        }
