想象一下,我将在.NET中进行异步调用,即HttpWebRequest.BeginGetResponse,并且不会在更广泛的范围内引用HttpWebRequest对象.垃圾收集器会破坏它并导致问题吗？

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..
    }
}
