ok, i'm lost. why 1st function wrong (squiglies in lambda expression), 2nd 1 right (meaning compiles)? public static expression<func<iproduct, string, bool>> isvalidexpression(string val) { return (h => h.product_name == val); } public static expression<func<iproduct, bool>> isvalidexpression2() { return (m => m.product_name == "ace"); } your first function going need 2 arguments. func<x,y,z> defines 2 parameters , return value. since have both iproduct , string parameters, you'll need 2 arguments in lambda. public static expression<func<iproduct, string, bool>> isvalidexpression(string val) { return ((h, i) => h.product_name == val); } your second function func<x,y> , means function signature has 1 parameter, , lambda statement compiles.

i have array, say: var arr1 = new [] { 1, 2, 3, 4, 5, 6 }; now, when array-size exceeds 5, want resize current array 3, , create new array contains upper 3 values, after action: arr1 = new [] { 1, 2, 3 }; newarr = new [] { 4, 5, 6 }; what's fastest way this? guess i'll have unmanaged corner, no clue. some more info: the arrays have able size without large performance hits the arrays contain int32's purpose of array group numbers in source array without having sort whole list in short: want split following input array: int[] arr = new int[] { 1, 3, 4, 29, 31, 33, 35, 36, 37 }; into arr1 = 1, 3, 4 arr2 = 29, 31, 33, 35, 36, 37 but because ideal speed reached array size of 3, arr2 should split 2 evenly sized arrays. note i know array's implementation in memory quite naive (well, @ least in c, can manipulate count of items in array array resizes). there memory move function somewhere in win32 api. guess fastest: change arr1 contai...

i have question regarding performance of .net httpwebrequest client (or webclient, gives similar results). if use httpwebrequest request html page (in case news.bbc.co.uk) , analyse speed (using httpanalyzer) @ response read application, slower browser (firefox, chrome, ie) requesting same resource (all caches cleared etc). .net application takes approximately 1.7 seconds versus 0.2 - 0.3 seconds browser. is purely down speed , efficiency of code / application or there other factors consider? code follows: httpwebrequest request = null; uri uritest = new uri("http://news.bbc.co.uk"); request = (httpwebrequest)webrequest.create(uritest); request.method = "get"; request.keepalive = true; request.headers["accept-encoding"] = "gzip, deflate"; httpwebresponse response = (httpwebresponse)request.getresponse(); response.close(); if make 2 requests second 1 happen more quickly? i have notice speed disparities between browsers...

i using samplemodel project mvvm foundation .why icommand returned when _decrementcommand declared relaycommand . know relaycommand inherits icommand won't clearer return relaycommand ? public icommand decrementcommand { { return _decrementcommand ?? (_decrementcommand = new relaycommand(() => --this.value)); } } relaycommand _decrementcommand; this principle of using least specific type can away with. concrete or specific types liability because more expose things callers don't need know , more need changed (making them implementation detail). in case, if return icommand, can change underlying command type without breaking callers. can expect callers won't have know more function should know, meaning less break oo principles.
