OleDbPermission Class

Definition

Caution

Code Access Security is not supported or honored by the runtime.

Enables the .NET Framework Data Provider for OLE DB to help make sure that a user has a security level sufficient to access an OLE DB data source.

Remarks

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.

Constructors

OleDbPermission()
Obsolete.
Obsolete.

Initializes a new instance of the OleDbPermission class.

OleDbPermission(PermissionState)

Initializes a new instance of the OleDbPermission class.

OleDbPermission(PermissionState, Boolean)
Obsolete.
Obsolete.

Initializes a new instance of the OleDbPermission class.

Properties

AllowBlankPassword

Gets a value indicating whether a blank password is allowed.

(Inherited from DBDataPermission)
Provider
Obsolete.

This property has been marked as obsolete. Setting this property will have no effect.

Methods

Add(String, String, KeyRestrictionBehavior)

Adds access for the specified connection string to the existing state of the DBDataPermission.

(Inherited from DBDataPermission)
Assert()

Declares 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)
Clear()

Removes all permissions that were previous added using the Add(String, String, KeyRestrictionBehavior) method.

(Inherited from DBDataPermission)
Copy()

Returns the OleDbPermission as an IPermission.

CreateInstance()

Creates a new instance of the DBDataPermission class.

(Inherited from DBDataPermission)
Demand()

Forces 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)
Deny()
Obsolete.
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)
Equals(Object)

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.

(Inherited from CodeAccessPermission)
FromXml(SecurityElement)

Reconstructs a security object with a specified state from an XML encoding.

FromXml(SecurityElement)

Reconstructs a security object with a specified state from an XML encoding.

(Inherited from DBDataPermission)
GetHashCode()

Gets 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)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
Intersect(IPermission)

Returns an IPermission that is the intersection of the current OleDbPermission and the specified target IPermission.

Intersect(IPermission)

Returns a new permission object representing the intersection of the current permission object and the specified permission object.

(Inherited from DBDataPermission)
IsSubsetOf(IPermission)

Returns a value indicating whether the current permission object is a subset of the specified permission object.

(Inherited from DBDataPermission)
IsUnrestricted()

Returns a value indicating whether the permission can be represented as unrestricted without any knowledge of the permission semantics.

(Inherited from DBDataPermission)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
PermitOnly()

Prevents 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)
ToString()

Creates and returns a string representation of the current permission object.

(Inherited from CodeAccessPermission)
ToXml()

Creates an XML encoding of the security object and its current state.

ToXml()

Creates an XML encoding of the security object and its current state.

(Inherited from DBDataPermission)
Union(IPermission)

Creates a database permission that is the union of the current permission and the specified permission.

Union(IPermission)

Returns a new permission object that is the union of the current and specified permission objects.

(Inherited from DBDataPermission)

Explicit Interface Implementations

IPermission.Demand()

Throws a SecurityException at run time if the security requirement is not met.

(Inherited from CodeAccessPermission)
IStackWalk.Assert()

Asserts that the calling code can access the resource identified by the current permission object, even if callers higher in the stack have not been granted permission to access the resource.

(Inherited from CodeAccessPermission)
IStackWalk.Demand()

Determines at run time whether all callers in the call stack have been granted the permission specified by the current permission object.

(Inherited from CodeAccessPermission)
IStackWalk.Deny()

Causes every Demand() for the current object that passes through the calling code to fail.

(Inherited from CodeAccessPermission)
IStackWalk.PermitOnly()

Causes every Demand() for all objects except the current one that pass through the calling code to fail, even if code higher in the call stack has been granted permission to access other resources.
