Creating a SharePoint 2010 page via the client object model

I am attempting to create pages in a Sharepoint 2010 pages library via the client object model but I cannot find any examples on how to do it. I have tried two approaches:

The first is to treat the Pages library as a l开发者_开发百科ist and try to add a list item.

static void createPage(Web w, ClientContext ctx)
{
    List pages = w.Lists.GetByTitle("Pages");
    //ListItem page = pages.GetItemById(0);
    ListItemCreationInformation lici = new ListItemCreationInformation();
    ListItem li = pages.AddItem(lici);
    li["Title"] = "hello";
    li.Update();
    ctx.ExecuteQuery();            
}

As expected, this failed with the error message:

To add an item to a document library, use SPFileCollection.Add()

The next approach I tried was to add it as a file. The problem is that the FileCreationInformation object is expecting a byte array and I am not sure what to pass to it.

static void createPage(Web w, ClientContext ctx)
{
    List pages = w.Lists.GetByTitle("Pages");
    FileCreationInformation file = new FileCreationInformation();
    file.Url = "testpage.aspx";
    file.Content = new byte[0];
    file.Overwrite = true;
    ctx.Load(pages.RootFolder.Files.Add(file));
    ctx.ExecuteQuery();    
}

The piece of code above will add an item in the Pages library but opening the file brings up a blank page which I cannot edit. From reading various topics, I suspect that it may only be possible to add pages via server side code. Any thoughts?

Thanks

The problem is that the FileCreationInformation object is expecting a byte array and I am not sure what to pass to it.

You could you whatever method you want to get the page contents into a string (read it from a file, create it using a StringBuilder, etc) and then convert the string to a byte array using

System.Text.Encoding.ASCII.GetBytes()

First of all, Publishing API is not supported via Client Side Object Model (CSOM) in SharePoint 2010. But you could consider the following approach that demonstrates how to create a publishing page using SharePoint 2010 CSOM.

How to create a publishing page using SharePoint 2010 CSOM

public static void CreatePublishingPage(ClientContext ctx, string listTitle, string pageName, string pageContent)
{
        const string publishingPageTemplate = "<%@ Page Inherits=\"Microsoft.SharePoint.Publishing.TemplateRedirectionPage,Microsoft.SharePoint.Publishing,Version=14.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c\" %> <%@ Reference VirtualPath=\"~TemplatePageUrl\" %> <%@ Reference VirtualPath=\"~masterurl/custom.master\" %>";
        var pagesList = ctx.Web.Lists.GetByTitle(listTitle);
        var fileInfo = new FileCreationInformation
        {
            Url = pageName,
            Content = Encoding.UTF8.GetBytes(publishingPageTemplate),
            Overwrite = true
        };
        var pageFile = pagesList.RootFolder.Files.Add(fileInfo);
        var pageItem = pageFile.ListItemAllFields;

        if (!ctx.Site.IsPropertyAvailable("ServerRelativeUrl"))
        {
            ctx.Load(ctx.Site);
            ctx.ExecuteQuery();
        }
        pageItem["PublishingPageLayout"] =  string.Format("{0}_catalogs/masterpage/ArticleLeft.aspx, ArticleLeft",ctx.Site.ServerRelativeUrl);
        pageItem["PublishingPageContent"] = pageContent;
        pageItem.Update();
        ctx.ExecuteQuery();
}

Usage

using (var ctx = new ClientContext(url))
{ 
     ctx.Credentials = new NetworkCredential("username", "password", "domain");
     CreatePublishingPage(ctx, "Pages", "Greetings.aspx", "Welcome to SharePoint!"); 
}
