How to get count of document libraries in a SharePoint site using SSOM?

To get the count of document libraries, we can use below simple code in SSOM:

using(SPSite site = new SPSite("https://yoursiteURL"))

{

  using (SPWeb web = site.OpenWeb())

  {

    SPListCollection librarycollection = Web.GetListsOfType(SPBaseType.DocumentLibrary);

    int count  = librarycollection .Count;

  }

}

Sweet and Simple. Hope this helps.!!!
