我已经扫描了标签[cefsharp]，我问的问题是以类似的形式出现的（请重新考虑重复的问题行动） .
我无法解决我认为应该是一个简单的请求 . 在浏览器控件中获取页面的html源并同步与winform控件交互 .
我在异步方面很弱，但设法通过我从这个标签[cefsharp]获得的几种方式来获取源代码 . 但是，任何与winform控件的交互都是从异步事件触发的，其中任何后续方法中的异步事件都会调用异步"mode"，因此任何winform控件交互 .
Example 1:
private async void Browser_LoadingStateChanged(object sender,
CefSharp.LoadingStateChangedEventArgs e)
{
if (!e.IsLoading)
{
//-- WORKS, but ...
string html = await Task.Run(Browser.GetSourceAsync);
//-- .. when calling other methods which interact with winform controls,
//-- I have to do so in the following way because I am not on the UI thread.
//-- therefore every control needs a block like this
if (InvokeRequired)
{
this.Invoke(new MethodInvoker(delegate
{
txtSource.Text = html;
}));
}
else
{
txtSource.Text = html;
}
}
}
Example 2: 我部分工作的另一个例子是这种方法 . 但是，通过按钮单击调用可以正常工作，而浏览器事件则不会
public string GetSource()
{
string result = null;
if (Browser.IsBrowserInitialized && !Browser.IsDisposed && !Browser.Disposing)
{
Task<string> task = Browser.GetSourceAsync();
var complete = task.ContinueWith(t =>
{
if (!t.IsFaulted)
{
result = t.Result;
}
}, TaskScheduler.Default);
complete.Wait();
}
return result;
}
private void button1_Click(object sender, EventArgs e)
{
//-- WORKS
txtSource.Text = GetSource();
}
private void Browser_LoadingStateChanged(object sender,
CefSharp.LoadingStateChangedEventArgs e)
{
if (!e.IsLoading)
{
//-- DOES NOT WORK. Hangs on waiting for the complete.Wait();
//-- note: this method is not async and neither the button too.
txtSource.Text = GetSource();
}
}
