想象一下,我将在.NET中进行异步调用,即HttpWebRequest.BeginGetResponse,并且HttpWebRequest对象在更广泛的范围内不被引用.垃圾收集器会毁灭它并造成问题吗？
示例代码：
- using System;
- using System.Net;
- public class AsyncHttpWebRequest
- {
- void Main()
- {
- var Request = HttpWebRequest.Create("http://www.contoso.com");
- var result = Request.BeginGetResponse(GetResponseCallback,null);
- }
- private void GetResponseCallback(IAsyncResult AsyncResult)
- {
- // Do Something..
- }
- }
备用版本(请求作为AsyncState传递)：
- using System;
- using System.Net;
- public class AsyncHttpWebRequest
- {
- void Main()
- {
- var Request = HttpWebRequest.Create("http://www.contoso.com");
- var result = Request.BeginGetResponse(GetResponseCallback,Request);
- }
- private void GetResponseCallback(IAsyncResult AsyncResult)
- {
- // Do Something..
- }
- }
