The DistributedTransactionPermission type exposes the following members.

  NameDescription
Public methodDistributedTransactionPermissionInitializes a new instance of the DistributedTransactionPermission class.
Top

  NameDescription
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 methodCopyCreates and returns an identical copy of the current permission. (Overrides CodeAccessPermission.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.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodFromXmlReconstructs a permission with a specified state from an XML encoding. (Overrides CodeAccessPermission.FromXml(SecurityElement).)
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 methodIntersectCreates and returns a permission that is the intersection of the current permission and the specified permission. (Overrides CodeAccessPermission.Intersect(IPermission).)
Public methodIsSubsetOfReturns a value that indicates whether the current permission is a subset of the specified permission. (Overrides CodeAccessPermission.IsSubsetOf(IPermission).)
Public methodIsUnrestrictedReturns a value that indicates whether unrestricted access to the resource that is protected by the current permission is allowed.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
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. (Overrides CodeAccessPermission.ToXml.)
Public methodUnionCreates a permission that is the union of the current permission and the specified permission. (Overrides CodeAccessPermission.Union(IPermission).)

A local transaction only consumes resources from a single durable source or mutilple volatitle 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.
