c# - Dapper How to Handle DBNull by DynamicParameter.Get - 


var param = new dynamicparameters(); param.add("msgid", dbtype.int32, direction: parameterdirection.output);  connection.execute(messageseloutmessageid, param, commandtype: commandtype.storedprocedure); count = param.get<int>("msgid");

by reference dapper, using code above call stored procedure output parameter - msgid. working fine in cases, there no value found stored procedure , returned output parameter value null. in these cases exception error below :

attempting cast dbnull non nullable type! note out/return parameters not have updated values until data stream completes (after 'foreach' query(..., buffered: false), or after gridreader has been disposed querymultiple)

understood mark return data type nullable avoid error code below 

count = param.get<int?>("msgid");

but there other way check param.get("msgid") == null instead of using nullable data type - int?

thanks paulius, tried dynamic datatype count = param.get<dynamic>("msgid"); , work i'm looking for.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
