asp.net webmethod async 寫法

 c#

====

[WebMethod]

public async static Task<string> 查詢Async()

{

using (var db = new Entities1())

{

var xxx =(await db.xxx.Where(a => ...).ToListAsync().ConfigureAwait(false)).Select(a => ...);

※加入 .ConfigureAwait(false) 避免無窮等待，原因可參考這篇，簡短說明參考:

To avoid performance degradation and possible dead-locks in ASP.NET or WPF applications (or any SynchronizationContext-dependent environment), you should always put ConfigureAwait(false) in your await statements:

javascript

====

$http.post('xxx.aspx/查詢Async', { })

.then(function (result) {

var newlist = JSON.parse(result.data.d.Result);

※回傳資料會放在Result裡面
