OleDbPermission serializable

OleDbPermission serializable

System.Data.OleDb (system.data.dll) sealed class

With this class, you can ensure that the current process has the required security level to access the OLE DB .NET provider before you attempt to open a connection. If it doesn't, a System.Security.SecurityException will be thrown. You can also use this class to programmatically revoke the permission to access the OLE DB .NET provider for the current method call.

Note that this class pertains only to code access security (the policy of allowed and disallowed actions you have configured using the .NET Framework Configuration Tool or the caspol .exe command-line utility). For more information, refer to the reference for the base class System.Data.Common.DBDataPermission . Currently, there are only two additional restrictions you can impose: denying the right to use blank passwords in a connection string and restricting the allowed OLE DB drivers.

 public sealed class  OleDbPermission  : System.Data.Common.DBDataPermission {  // Public Constructors  public  OleDbPermission  (  );      public  OleDbPermission  (System.Security.Permissions.PermissionState   state   );    public  OleDbPermission  (System.Security.Permissions.PermissionState   state   ,        bool   allowBlankPassword   );  // Public Instance Properties  public string  Provider  {set; get; }  // Public Instance Methods  public override IPermission  Copy  (  );  // overrides System.Data.Common.DBDataPermission  public override void  FromXml  (System.Security.SecurityElement   securityElement   );  // overrides System.Data.Common.DBDataPermission  public override IPermission  Intersect  (System.Security.IPermission   target   );  // overrides System.Data.Common.DBDataPermission  public override SecurityElement  ToXml  (  );  // overrides System.Data.Common.DBDataPermission  public override IPermission  Union  (System.Security.IPermission   target   );  // overrides System.Data.Common.                  DBDataPermission  }
