Programmatically uploading and setting permission to a document in a document library in SharePoint

We can use the following code for uploading a document to document library.

// create a filestream object and open an existing file for reading its contents

FileStream oFileStream = File.OpenRead(@”C:\G.doc”);

byte[] content = new byte[oFileStream.Length];

// store the contents in a byte array

oFileStream.Read(content, 0, (int)oFileStream.Length);


// create an SPSIte object

using (SPSite objSite = new SPSite(“http://d-1246”))


// get reference to the web application or web site

using (SPWeb objWeb = objSite.OpenWeb())


// get reference to the document library. Proposal – name of the document library

SPFolder mylibrary = objWeb.Folders[“Proposal”];

objWeb.AllowUnsafeUpdates = true;

// add the file to the document library and update it

SPFile myFile = mylibrary.Files.Add(“MyProposal.doc”, content, true);


// get the reference to the file just uploaded as a SPListItem for setting permissions

SPListItem myListItem = myFile.Item;

// HasUniqueRoleAssignments – returns false if it inherits permission from parent else true


// BreakRoleInheritance – breaking role inheritance so that we can define our own permissions


// webroledefinitions – Full Right, Design, Contribute and Read

SPRoleDefinitionCollection webroledefinitions = objWeb.RoleDefinitions;

// group – different groups created in that site

SPGroup group = objWeb.SiteGroups[“MyGroup”];

SPRoleAssignment roleassignment = new SPRoleAssignment(group);



// same for the user as well

SPUser user = objWeb.SiteUsers[@”domainname\username”];

SPRoleAssignment roleassignment1 = new SPRoleAssignment(user);

roleassignment1.RoleDefinitionBindings.Add(webroledefinitions[“Full Control”]);

  1. Hi,

    Im looking out for a script which
    automates the archival policy processes.

    I would have a dump of documents and an excel sheet provided with the following columns:
    Old File Name
    New File Name
    Folder Name (where files need to be moved)
    Ad–ID to provide access at files

    Script should read the information from the excel sheet to perform the following actions into WSS:

    · Re-naming of files as per the new file name mentioned in the sheet.

    · Movement of files to a particular folder as per the folder name mentioned in the sheet.

    · Automatic access to the files as per the Ad-Id mentioned in the sheet.

    System should validate the access of the document for each user.

    I would be grateful if you could assist me on this

    Thanks & Regards,
    narayanan rm.


  2. The topic is to much informative but what we have to do if i have a document already uploded..and i want a refrence a that file i.e abc.doc.Please help me if someone have knowledge about it.
    Thanks in Advance


  3. thank you so much. The post was helpgful. I have another question. I have a folder and a subfolder inside that which is hiiden and the file inside the subfolder. I need to access the worflow status column of the file and update it in the folder workflow column. Any help in this is appreciated


  4. Thanks for your post.I want to know if it is possible to create application from sharepoint that can integrate outlook 2007 by creating alert programatically.


  5. This is the easiest way of usage, but a fairly good example.
    Suggest to extend this with using SPItemEvent, f.e. ItemUploaded, add som extra, f.e. RunWithElevated privileges and AD group handling, not just trivial SPGroup.
    This way the sample would be more realistic.


  6. by applying this method permissions are set on item not on document , if user who has read permission can download document , edit the document and saved the changes to server ,
