PnrpPermission.Union(IPermission) Method

Definition

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

public override System.Security.IPermission Union (System.Security.IPermission target);

Parameters

target
IPermission

A permission to combine with the current permission. It must be of the same type as the current permission.

Returns

A new permission that represents the Union(IPermission) of the current PnrpPermission and the specified permission.

Exceptions

target parameter is invalid.

Remarks

The result of a call to Union is a permission that represents all the operations represented by both the current PnrpPermission and the specified permission. Any demand that passes either permission passes their union.

The following statements are required to be true for all implementations of the Union method. X and Y represent IPermission objects that are not a null reference (Nothing in Visual Basic).

  • X.Union(X) returns an object that has the same value as X.

  • X.Union(Y) returns an object that has the same value as the object returned by Y.Union(X).

  • X.Union(a null reference (Nothing in Visual Basic)) returns an object that has the same value as X.
