I am able to getTitle of web Part but I need the content

Answer 1

The CSOM LimitedWebPartManager only allows import of a web part, but not export. So no, you cannot access the Content property.

There is an Office UserVoice suggestion to introduce this CSOM capability: https://officespdev.uservoice.com/forums/224641-general/suggestions/6413925-expose-microsoft-sharepoint-webpartpages-splimited

As an alternative for now, you may use the GetWebPart2 method of the WebPartPagesWebService to get the content: https://msdn.microsoft.com/en-us/library/aa979489(v=office.12).aspx

Answer 2

If this helps someone else,

using(ClientContext ctx = new ClientContext("siteURL")) {  
  SecureString password = new SecureString();
  ctx.Credentials = new SharePointOnlineCredentials("onlineEmail", password);
  File file = ctx.Web.GetFileByServerRelativeUrl("/pages/default.aspx");
  LimitedWebPartManager wpManager = file.GetLimitedWebPartManager(PersonalizationScope.Shared);
  Guid wpID= new Guid("{GUID}");
  ClientResult<string> wpXml= wpManager.ExportWebPart(wpID);
  ctx.ExecuteQuery();

  //Parse wpXml.Value to get Content Element
}
