问题 I know that, we can use Readonly< T> to redeclare all fields of T as readonly, as in: [Typescript: extending an interface and redeclaring the existing fields as readonly What about nested fields? For example: interface School { teachers: Array<Teacher>; students: Array<Student>; } interface Teacher { teacherId: number; personInfo: PersonInfo; } interface Student { studentId: number; personInfo: PersonInfo; } interface PersonInfo { name: string; age: number } How to create a SchoolReadonly

问题 I have a class Bar with a private field containing the reference type Foo . I would like to expose Foo in a public property, but I do not want the consumers of the property to be able to alter Foo ... It should however be alterable internally by Bar , i.e. I can't make the field readonly . So what I would like is: private _Foo; public Foo { get { return readonly _Foo; } } ...which is of course not valid. I could just return a clone of Foo (assumming that it is IClonable ), but this is not

问题 I am periodically getting Word documents from various clients and sometimes they send them to me in 'Read-Only' mode. While it isn't a big deal to go to 'View > Edit Document' manually, I cannot seem to find how to do this within my VBA code. Either opening a document as editable or toggling it as editable once it is open would be sufficient for my needs. Note that I cannot open the document with 'readOnly = false' as it looks like it is set to 'readOnly recommended' (based on my reading of

问题 I'm extracting an ISO and then copying a folder from the extracted ISO. The problem is that the extracted files are read-only. I've tried changing it from the properties menu, and from code in c#. Neither worked. The code I used for extracting the ISO is in another question: extract ISO with winrar automatically with c# or batch I'm looking for a way to either change the attributes of the extracted ISO so that I can copy from its subfolders, or to just change the sub folders permissons.
