Methods

public IPermission
AddPermission​(IPermission perm)
perm The permission to add.
Returns The union of the permission added and any permission of the same type that already exists in the <see cref="T:System.Security.PermissionSet" /> .
Adds a specified permission to the <see cref="T:System.Security.PermissionSet" /> .
protected IPermission
AddPermissionImpl​(IPermission perm)
perm The permission to add.
Returns The union of the permission added and any permission of the same type that already exists in the <see cref="T:System.Security.PermissionSet" /> , or <see langword="null" /> if <paramref name="perm" /> is <see langword="null" /> .
Adds a specified permission to the <see cref="T:System.Security.PermissionSet" /> .
public void
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 <see cref="M:System.Security.PermissionSet.Assert" /> can create security vulnerabilities.
public bool
ContainsNonCodeAccessPermissions​()

public PermissionSet
Copy​()
Returns A copy of the <see cref="T:System.Security.PermissionSet" /> .

array The target array to which to copy.
index The starting position in the array to begin copying (zero based).
Copies the permission objects of the set to the indicated location in an <see cref="T:System.Array" /> .
public void
Demand​()
Forces a <see cref="T:System.Security.SecurityException" /> at run time if all callers higher in the call stack have not been granted the permissions specified by the current instance.
public void
Deny​()
Causes any <see cref="M:System.Security.PermissionSet.Demand" /> that passes through the calling code for a permission that has an intersection with a permission of a type contained in the current <see cref="T:System.Security.PermissionSet" /> to fail.
public bool
Equals​(object o)
o The object to compare with the current <see cref="T:System.Security.PermissionSet" /> .
Returns <see langword="true" /> if the specified object is equal to the current <see cref="T:System.Security.PermissionSet" /> object; otherwise, <see langword="false" /> .

et The XML encoding to use to reconstruct the security object.
Reconstructs a security object with a specified state from an XML encoding.
GetEnumerator​()
Returns An enumerator object for the permissions of the set.

GetEnumeratorImpl​()
Returns An enumerator object for the permissions of the set.
Returns an enumerator for the permissions of the set.
public int
GetHashCode​()
Returns A hash code for the current <see cref="T:System.Security.PermissionSet" /> object.
Gets a hash code for the <see cref="T:System.Security.PermissionSet" /> object that is suitable for use in hashing algorithms and data structures such as a hash table.
public IPermission
GetPermission​(Type permClass)
permClass The type of the desired permission object.
Returns A copy of the permission object of the type specified by the <paramref name="permClass" /> parameter contained in the <see cref="T:System.Security.PermissionSet" /> , or <see langword="null" /> if none exists.
Gets a permission object of the specified type, if it exists in the set.
protected IPermission
GetPermissionImpl​(Type permClass)
permClass The type of the permission object.
Returns A copy of the permission object, of the type specified by the <paramref name="permClass" /> parameter, contained in the <see cref="T:System.Security.PermissionSet" /> , or <see langword="null" /> if none exists.
Gets a permission object of the specified type, if it exists in the set.
public PermissionSet
Intersect​(PermissionSet other)
other A permission set to intersect with the current <see cref="T:System.Security.PermissionSet" /> .
Returns A new permission set that represents the intersection of the current <see cref="T:System.Security.PermissionSet" /> and the specified target. This object is <see langword="null" /> if the intersection is empty.
