我如何知道我是否正确地执行了异步页面

Question

我有这个指令的aspx：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Logs.aspx.cs" Inherits="Logs_Logs" Async="true" %>

和.cs：

.....

private readonly Action<string> zipArquivoAction;

public Logs_Logs()
{
    zipArquivoAction = ZipArquivo;
}

protected void LkbGZip_Click(object sender, EventArgs e)
{
    LinkButton lkbGZip = (LinkButton) sender;
    AddOnPreRenderCompleteAsync(BeginAsyncOperation, EndAsyncOperation, lkbGZip.CommandArgument);
}

IAsyncResult BeginAsyncOperation(object sender, EventArgs e, AsyncCallback cb, object state)
{
    return zipArquivoAction.BeginInvoke((string)state, cb, state);
}

void EndAsyncOperation(IAsyncResult ar)
{
    zipArquivoAction.EndInvoke(ar);
}

private void ZipArquivo(string arquivoCaminho)
{
    System.Threading.Thread.Sleep(10000);
}

如果我在任何方法中都设置断点并调用System.Threading.Thread.CurrentThread，则始终返回相同的Thread，这意味着我没有使用IO Thread，对吗？

System.Threading.Thread.CurrentThread
{System.Threading.Thread}
    base {System.Runtime.ConstrainedExecution.CriticalFinalizerObject}:             
{System.Threading.Thread}
    ApartmentState: MTA
    CurrentCulture: {pt-BR}
    CurrentUICulture: {pt-BR}
    ExecutionContext: {System.Threading.ExecutionContext}
    IsAlive: true
    IsBackground: true
    IsThreadPoolThread: true
    ManagedThreadId: 5
    Name: null
    Priority: Normal
    ThreadState: Background

Answer 1

打开跟踪并查找对Begin AsyncOperation和End AsyncOperation的调用。 这些应该出现在End PreRender之后。
