Answer 2

Using managed client object model, you can add web part to the the page. You just need to have Url of the page.

using (ClientContext context =new ClientContext(""))
{
   Web web = context.Web;
   File file = web.GetFileByServerRelativeUrl("Page Url");//Page Url is the page where you want to add webpart.Doc lib view.keep all libraries in collection and traverse and get the view url of it
   context.Load(file);
   context.ExecuteQuery();
   LimitedWebPartManager wpm = file.GetLimitedWebPartManager(PersonalizationScope.Shared);
   WebPartDefinition def = wpm.ImportWebPart(WebpartData);
   wpm.AddWebPart(def.WebPart, "Main", 0);
   context.ExecuteQuery();
}

what is WebpartData data?

WebPartDefinition def = wpm.ImportWebPart(WebpartData);

WebpartData is the string variable which contains webpart data in xml.

Initially add your CEWP on one page and export this webpart and assign the content of .dwp file to WebpartData before above code.

for example.

   public static string WebpartContent = @"<WebPart                xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns=""http://schemas.microsoft.com/WebPart/v2"">
