c# - Filter Generic List by multiple values -

is a general list of documents, how can I filter it by DOS ID 1 and 2?

I have tried the following link but it is not working. I need to filter the list and use it as a data source.

  list & lt; VisitDocs & gt; ListD = default (list & visit; Docs & gt;); Results = Dico in Docs from Docs in the Doc. DOSID == 1 & amp; Amp; Docs.DocID == 2docs; RptDocs.DataSource = listD;    
 
 
 You should  : 
 
 < Code> results = list D. Where (Doctor => doc.DocID == 1 || doc.DocID == 2);  
 
 or 
 
  result = docs in the list where in the docs. DOSID == 1 || Docs. Choose dosid == 2 docs;  
 
 Your  DocID  can be  1  or  2 , it can not be both. Your current status is  & amp; Amp;  which means that it should be  1  and  2  at the same time. To assign to  Datasource  call  toList : 
 
  rptDocs.DataSource = result.ToList ();
