C# 跳过所有代理异常 - 超时

发布于 2024-11-10 05:37:16 字数 450 浏览 1 评论 0原文

有什么方法可以跳过/捕获所有代理异常吗？也许还可以设置一个超时，这样程序就不会卡在中间

webProxy = new WebProxy("" + prox + "");
webProxy.Credentials = CredentialCache.DefaultCredentials;
wr.Proxy = webProxy;

我已经添加了

             catch (Exception ex)
            {
                // Do nothing or log
                var exceptio = ex.ToString();
                richTextBox1.Text = exceptio;
            }

如何设置一个超时？

Is there any way i can skip/catch all proxy exceptions?
And also maybe put a time-out so the program wont get stuck in-between

webProxy = new WebProxy("" + prox + "");
webProxy.Credentials = CredentialCache.DefaultCredentials;
wr.Proxy = webProxy;

I've added

             catch (Exception ex)
            {
                // Do nothing or log
                var exceptio = ex.ToString();
                richTextBox1.Text = exceptio;
            }

how can i put a time-out on it?

try/catch 块对此有帮助吗？

正如建议的，您需要将执行代码包含在 try/catch 块中。
您可以在调试/异常...（在 Visual Studio 中）下摆弄调试器异常处理，但无论如何，任何未处理的异常将始终触发调试器中断。

try
{
    // Do work that might fail
}
catch (Exception ex)
{
    // Do nothing or log
    Trace.WriteLine(ex);
}

有关调试和异常的更多信息，请参见此处

关于超时，您将其放在 WebRequest 对象上，而不是放在代理上，如下所示：

WebProxy webProxy = new WebProxy("http://myproxyserver:80/");
WebRequest webRequest = WebRequest.Create("http://www.stackoverflow.com");
webRequest.Proxy = webProxy;
webRequest.Timeout = 5000;  // <-- Set time out here, in milliseconds
...

阅读有关超时的更多信息此处。

As suggested you need to enclose the executing code in a try/catch block.
You can fiddle around with debugger Exception handling under Debug/Exceptions... (in Visual Studio) but regardless, any non-handled exception will always trigger the debugger to break.

try
{
    // Do work that might fail
}
catch (Exception ex)
{
    // Do nothing or log
    Trace.WriteLine(ex);
}

More on debugging and exceptions can be found here

Regarding time-out, you put it on the WebRequest object, not on the proxy, like so:

WebProxy webProxy = new WebProxy("http://myproxyserver:80/");
WebRequest webRequest = WebRequest.Create("http://www.stackoverflow.com");
webRequest.Proxy = webProxy;
webRequest.Timeout = 5000;  // <-- Set time out here, in milliseconds
