Adds a specified permission to the PermissionSet.

C# 
protected virtual System.Security.IPermission? AddPermissionImpl(System.Security.IPermission? perm);
C# 
protected virtual System.Security.IPermission AddPermissionImpl(System.Security.IPermission perm);

Parameters

perm
IPermission

The permission to add.

Returns

IPermission

The union of the permission added and any permission of the same type that already exists in the PermissionSet, or null if perm is null.

Exceptions

InvalidOperationException

The method is called from a ReadOnlyPermissionSet.

Remarks

The AddPermissionImpl method is the implementation for the AddPermission method.

If a permission of the same type as the added permission already exists in the PermissionSet, the new permission is the union of the existing permission object and the specified permission object. For example, if a permission that implements IUnrestrictedPermission is added to an UnrestrictedPermissionSet, the resulting union is the original Unrestricted PermissionSet.
