Namespace:  System.Data.OleDb
Assembly:  System.Data (in System.Data.dll)

[SerializableAttribute]
public sealed class OleDbPermission : DBDataPermission

The OleDbPermission type exposes the following members.

  NameDescription
Public methodOleDbPermission() Obsolete. Initializes a new instance of the OleDbPermission class.

  NameDescription
Public methodAddAdds access for the specified connection string to the existing state of the DBDataPermission. (Inherited from DBDataPermission.)
Public methodAssertDeclares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. Using Assert can create security issues. (Inherited from CodeAccessPermission.)
Public methodCopyReturns the OleDbPermission as an IPermission. (Overrides DBDataPermission.Copy().)
Public methodDemandForces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodDeny Obsolete. Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodEqualsDetermines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission.)
Public methodFromXmlReconstructs a security object with a specified state from an XML encoding. (Inherited from DBDataPermission.)
Public methodGetHashCodeGets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table. (Inherited from CodeAccessPermission.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIntersectReturns a new permission object representing the intersection of the current permission object and the specified permission object. (Inherited from DBDataPermission.)
Public methodIsSubsetOfReturns a value indicating whether the current permission object is a subset of the specified permission object. (Inherited from DBDataPermission.)
Public methodIsUnrestrictedReturns a value indicating whether the permission can be represented as unrestricted without any knowledge of the permission semantics. (Inherited from DBDataPermission.)
Public methodPermitOnlyPrevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodToStringCreates and returns a string representation of the current permission object. (Inherited from CodeAccessPermission.)
Public methodToXmlCreates an XML encoding of the security object and its current state. (Inherited from DBDataPermission.)
Public methodUnionReturns a new permission object that is the union of the current and specified permission objects. (Inherited from DBDataPermission.)

This class is intended for future use when the .NET Framework Data Provider for OLE DB is enabled for partial trust scenarios. The .NET Framework Data Provider for OLE DB currently requires FullTrust permission. Currently, using the OleDbPermission class has no effect. For more information, see Code Access Security and ADO.NET.
