documet upload in REST c# is giving 401 un-authirized error

the following code in c# in auto hosted app upload document giving 401 unauthorized error. please let me know.

httpwebrequest endpointrequest = (httpwebrequest)httpwebrequest.create(hostweb + "/_api/web/getfolderbyserverrelativeurl('shared%20documents'/files/add(url='" + filename + "',overwrite=true))");
                endpointrequest.method = "post";

                endpointrequest.accept = "application/json;odata=verbose";                
                endpointrequest.headers.add("authorization", "bearer" + accesstoken);
                endpointrequest.headers.add("binarystringrequestbody", "true");
                var reqstream = endpointrequest.getrequeststream();
                reqstream.write(bytefile, 0, bytefile.length);
                reqstream.flush();
                reqstream.close();

                httpwebresponse endpointresponse = (httpwebresponse)endpointrequest.getresponse();

              

assuming accesstoken valid, found couple typos/syntax errors in code:

• should be: /web/getfolderbyserverrelativeurl('shared%20documents')/files/add(url='" + filename + "',overwrite=true) -- didn't close parenthesis after shared%20documents , had parenthesis @ end
  
• should be: "bearer " + accesstoken -- didn't have space after bearer

the following code worked me in autohosted app:

httpwebrequest endpointrequest = (httpwebrequest)httpwebrequest.create(hostweb + "/_api/web/getfolderbyserverrelativeurl('shared%20documents')/files/add(url='" + filename + "',overwrite=true)"); endpointrequest.method = "post"; endpointrequest.headers.add("binarystringrequestbody", "true"); endpointrequest.headers.add("authorization", "bearer " + accesstoken); endpointrequest.getrequeststream().write(bytefile, 0, bytefile.length);  httpwebresponse endpointresponse = (httpwebresponse)endpointrequest.getresponse();
