DistributedTransactionPermission Class

Definition

Namespace:

System.Transactions

Assembly:

System.Security.Permissions.dll

Caution

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

The permission that is demanded by System.Transactions when management of a transaction is escalated to MSDTC. This class cannot be inherited.

Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

A local transaction only consumes resources from a single durable source or multiple volatile sources. A distributed transaction, on the other hand, has to interact with multiple durable resources, potentially across the network. When management of a transaction is escalated to MSDTC, the code that initiated the escalation is verified to have this permission. For more information on security levels, see Security Trust Levels in Accessing Resources. For more information on transaction management escalation, see Transaction Management Escalation. The security demand affects the code that initiated the escalation, not necessarily the code that originally created the local transaction.

Constructors

DistributedTransactionPermission(PermissionState)

Initializes a new instance of the DistributedTransactionPermission class.

Methods

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)
Copy()	Creates and returns an identical copy of the current permission.
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. 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 permission with a specified state from an XML encoding.
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)	Creates and returns a permission that is the intersection of the current permission and the specified permission.
IsSubsetOf(IPermission)	Returns a value that indicates whether the current permission is a subset of the specified permission.
IsUnrestricted()	Returns a value that indicates whether unrestricted access to the resource that is protected by the current permission is allowed.
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.
Union(IPermission)	Creates a permission that is the union of the current permission and the specified permission.
