c# - Document DB query -

i'm trying query 1 of documents documentdb doesn't appear working, how set up:

nosqlservice:

private inosqlprovider client; private static icontainer container;  public nosqlservice(inosqlprovider provider) {     client = provider; }  public static dynamic querydocument<t>(uri reference, feedoptions queryoptions) {     var documentdb = container.resolve<inosqlprovider>();     return documentdb.querydocumentasync(reference, queryoptions); } 

inosqlprovider:

iorderedqueryable<document> querydocumentasync(uri reference, feedoptions queryoptions); 

azuredocumentdbservice

azuredocumentdbservice inherits inosqlprovider

private readonly idocumentclient client;  public iorderedqueryable<document> querydocumentasync (uri reference, feedoptions queryoptions) {     return client.createdocumentquery(reference, queryoptions); } 

azuredocumentdbtest

feedoptions queryoptions = new feedoptions();  documents document = new documents();  document.id = "112";  queryoptions.maxitemcount = -1;  var reference = nosqlservice.createdocumenturi("ppsession1", "callumtest"); iqueryable<documents> documentquery = nosqlservice.querydocument<documents>(reference, queryoptions).where(document.id = "112");  foreach (documents documents in documentquery) {     console.writeline("\tread {0}", documents);  } 

when run test exception:

microsoft,csparp.runtimebuilder.runtimebinderexception: 'object' not contain definition 'where'.

you returning dynamic nosqlservice.querydocument , trying apply linq extension method where on it. cannot do. have cast can work extension.

so either change nosqlservice using dynamic

public static iqueryable<document> querydocument<t>(uri reference, feedoptions queryoptions) {     var documentdb = container.resolve<inosqlprovider>();     return documentdb.querydocumentasync(reference, queryoptions); } 

or cast result in test

var reference = nosqlservice.createdocumenturi("ppsession1", "callumtest"); iqueryable<document> documentquery = ((iqueryable<document>)nosqlservice.querydocument<document>(reference, queryoptions)).where(document => document.id == "112");
