I have been able to add a web part, thank to this post, using code like:
limitedWebPartManager.ImportWebPart(webPartSchemaXml)
However now I'm not able to remove the Web Part anymore by Editing the Page, because the Web Part is not visible in Edit mode (incidentally I don't know why).
So I'm trying to Remove the Web Part programatically, but LimitedWebPartManager doesn't offer a method like RemoveWebPart.
Use DeleteWebPart method of WebPartDefinition class to delete web part from the page.
Demo:
class Program
{
private class Configuration
{
public static string ServiceSiteUrl = "https://<tenant>.sharepoint.com/sites/<site>";
public static string ServiceUserName = "<user>@<tenant>.onmicrosoft.com";
public static string ServicePassword = "<password>";
}
static ClientContext GetonlineContext()
{
var securePassword = new SecureString();
foreach (char c in Configuration.ServicePassword)
{
securePassword.AppendChar(c);
}
var onlineCredentials = new SharePointOnlineCredentials(Configuration.ServiceUserName, securePassword);
var context = new ClientContext(Configuration.ServiceSiteUrl);
context.Credentials = onlineCredentials;
return context;
}
static void Main(string[] args)
{
var ctx = GetonlineContext();
var page = ctx.Web.GetFileByServerRelativeUrl("/sites/<SiteCollection>/SitePages/<page>.aspx");
LimitedWebPartManager limitedWebPartManager = page.GetLimitedWebPartManager(PersonalizationScope.Shared);
ctx.Load(limitedWebPartManager.WebParts,
wps => wps.Include(
wp => wp.WebPart.Title));
ctx.ExecuteQuery();
if (limitedWebPartManager.WebParts.Count == 0)
{
throw new Exception("No Web Parts to delete.");
}
WebPartDefinition webPartDefinition = limitedWebPartManager.WebParts[0];
webPartDefinition.DeleteWebPart();
ctx.ExecuteQuery();
}
}

(Though these articles are for SharePoint 2010, they still have good information for SharePoint Online.)
