Access, Copy, and Move Files

To retrieve files and folders from a Web site, use the GetFile or GetFolder method of the SPWeb class.

You can use the GetFolder method of the SPWeb class to return a specified folder. Then you can access individual files in the folder. After instantiating an SPWeb object (for example, as oWebsite), use SPFolder oFolder = oWebsite.GetFolder("Shared Documents") (in Microsoft Visual Basic, use Dim oFolder As SPFolder = oWebsite.GetFolder("Shared Documents")) to return the Shared Documents folder for the site.

using (SPWeb oWebsite = new SPSite("http://Server/sites/SiteCollection").OpenWeb())
{
    string folderUrl = "/Shared Documents/MySubFolder";
    SPFolder oFolder = oWebsite.GetFolder(folderUrl);
    SPFileCollection collFile = oFolder.Files;

    foreach (SPFile oFile in collFile)
    {
        Label1.Text += "<BR>Url: " + oFile.Url.ToString() + " Size: " + oFile.Length.ToString();
    } 
}
