Which code segment should you add at line 11?

You have a document library named Documents. Minor and major version management is enabled for the document library.

You plan to add a document named MyFile.docx to Documents.

You create a console application that contains the following code segment. (Line numbers are included for reference only.)

01 using (SPSite site = new SPSite(“http://intranet”))
02 {
03 SPList documents = site.RootWeb.Lists[“Documents”];
04 FileStream fstream = File.OpenRead(@”MyFile.docx”);
05 byte[] content = new byte[fstream.Length];
06 fstream.Read(content, 0, (int)fstream.Length);
07 fstream.Close();
08 site.RootWeb.Files.Add(documents.RootFolder.Url + “/MyFile.docx”, content, true);
09 SPFile file = site.RootWeb.GetFile(documents.RootFolder.Url + “/MyFile.docx”);
10 file.CheckIn(string.Empty);
11
12 }

You need to ensure that all users can see the document.

A.
file.CanOpenFile(true);

Explanation:
MNEMONIC RULE: “Minor and major versions to Publish”

Minor and major version management is enabled for the document library; therefore, we must use Publish() method.

SPFile.Publish Method
