Correct usage of SPFileCollection.Add() overloaded method in SPS 2003

  • Article

I was recently involved in a case involving SPFileCollection.Add() method. When we use one of the overloads of Add() method the “Created” & “Modified” dates weren’t correct (+5:30 hrs at my end & -7 hrs at the customer’s end – not exactly sure why, perhaps it’s defaulting to GMT as that appears to be the only logical reason). The following are the overloaded methods in SPFileCollection.Add() method.

· Add(string strUrl,byte[]file, bool overwrite)

· Add(string strUrl,byte[] file)

· Add(string strUrl,byte[] file,SPUser createdBy,SPUser modifiedBy,DateTime timeCreated,DateTime timeLastModified)

If we use the last overloaded method and provide DateTime.Now as the values for timeCreated & timeLastModified, we’ll see a difference in time between the time the document was uploaded and the time that shows up in the document library against “Created” & “Modified” fields. Looks like DateTime.Now (by default) picks up GMT time. Note: The other overloaded methods return the correct date & time.

A simple fix is to use DateTime.Now.ToUniversalTime()instead.

With my limited search experience, I was not able to find thing small information recorded yet. So, thought of blogging this and saving some of your time J

A quick sample here:

static void Main(string[] args)

{

SPSite site = new SPSite("https://<sharepointserverurl>");

SPWeb web = site.OpenWeb();

SPFolder folder = web.GetFolder("shared documents");

SPUser user = site.Owner;

FileStream fs = new FileStream("test.doc",FileMode.Open);

byte[] fileContents = new byte[(int)fs.Length];

fs.Read(fileContents,0,(int)fs.Length);

fs.Close();

SPFile file = folder.Files.Add("test.doc",fileContents,user,user,DateTime.Now.ToUniversalTime(),DateTime.Now.ToUniversalTime());

Console.WriteLine("Successfully uploaded document");

Console.Read();

}
