Methods for connecting strings in C# encryption

This article describes the method of connecting strings in C# encryption. Share it for your reference. The details are as follows:

The connection string contains the database access information, account number and password, so it is generally not displayed in plain text. This code is used to encrypt the connection string.

public static class EncryptConnection
{
  public static void EncryptConnectionString(bool encrypt)
  {
   Configuration configFile = null;
   try
   {
    // Open the configuration file and retrieve the connectionStrings section.
    configFile = ();
    ConnectionStringsSection configSection = ("connectionStrings") as ConnectionStringsSection;
    if ((!()) && (!()))
    {
     if (encrypt && !)
     //encrypt is false to unencrypt
     {
      ("DataProtectionConfigurationProvider");
     }
     if (!encrypt && )
     //encrypt is true so encrypt
     {
      ();
     }
     //re-save the configuration file section
      = true;
     // Save the current configuration.
     ();
    }    
   }
   catch ( ex)
   {
    throw (ex);
   }
   finally
   {
   }
  }
}
