本文實例講述了C#加密app.config中銜接字符串的辦法。分享給年夜家供年夜家參考。詳細以下：

銜接字符串中包括數據庫的拜訪信息，帳號和暗碼，是以普通不以明文顯示，本代碼用來加密銜接字符串。

public static class EncryptConnection
{
  public static void EncryptConnectionString(bool encrypt)
  {
   Configuration configFile = null;
   try
   {
    // Open the configuration file and retrieve the connectionStrings section.
    configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
    ConnectionStringsSection configSection = configFile.GetSection("connectionStrings") as ConnectionStringsSection;
    if ((!(configSection.ElementInformation.IsLocked)) && (!(configSection.SectionInformation.IsLocked)))
    {
     if (encrypt && !configSection.SectionInformation.IsProtected)
     //encrypt is false to unencrypt
     {
      configSection.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");
     }
     if (!encrypt && configSection.SectionInformation.IsProtected)
     //encrypt is true so encrypt
     {
      configSection.SectionInformation.UnprotectSection();
     }
     //re-save the configuration file section
     configSection.SectionInformation.ForceSave = true;
     // Save the current configuration.
     configFile.Save();
    }    
   }
   catch (System.Exception ex)
   {
    throw (ex);
   }
   finally
   {
   }
  }
}
