Optimized Object model API code for uploading large files to a SharePoint document library

  • Artikkeli

The following code block contains an optimized code for uploading large files (>500 MB) to a SharePoint document library. This code may be used to circumvent Out of Memory exceptions when the process loads the entire file in memory for uploading.

 

 

//Get the FileName from the fully qualified path

string strFileName = Path.GetFileName(strFileFullName);

// siteURL = URL of the web on which the file will be uploaded

using (SPSite sitecollection = new SPSite(siteURL))

{

using (SPWeb site = new SPSite(siteURL).OpenWeb())

      {

      site.AllowUnsafeUpdates = true;

            StreamReader reader = new StreamReader(strFileFullName);

            //docLibGuid = GUID of the Document Library where the file will be uploaded

            SPDocumentLibrary targetDocLib = (SPDocumentLibrary)site.Lists[docLibGuid];

            string libraryRelativePath = targetDocLib.RootFolder.ServerRelativeUrl;

            string libraryPath = sitecollection.MakeFullUrl(libraryRelativePath);

            string documentPath = libraryPath + "/" + strFileName;

            strFolderUrl = libraryPath + "/";

            site.Files.Add(documentPath, reader.BaseStream, true);

            site.AllowUnsafeUpdates = false;

            reader.Close();

            reader.Dispose();

      }

}

    I think there are a few tweaks to make this code even better, but it seems pretty good. One issue is
