“System.Net.WebException"类型的异常 [英] An exception of type 'System.Net.WebException'

问题描述

我正在开发 WP7-8 应用程序，该应用程序使用 RestClient 从 WebServer 获取信息.当我关闭互联网连接时，我看到:

I'm working on WP7-8 application which is using RestClient for getting info from WebServer. When I swich off internet connection I see:

System.Net.WebException"类型的异常发生在System.Windows.ni.dll 并且在托管/本机之前未处理边界

An exception of type 'System.Net.WebException' occurred in System.Windows.ni.dll and wasn't handled before a managed/native boundary

什么意思?我应该如何或应该修复它?我的代码:

What does it mean? How or should I fix it? My code:

 RestSharp.RestClient _client;
_client = new RestClient { BaseUrl = BaseURL };
_client.Timeout = 50;

resourceString = "Http:\\blablabla"; 
var request = new RestRequest { RequestFormat = DataFormat.Xml, Resource = resourceString };
request.Timeout = 50;
request.IncreaseNumAttempts();

if (System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable() != true)
{
    ErrorCallback("Internet connection Error");
    return;
}
_client.ExecuteAsync(request, response =>
{
    return response;
}

推荐答案

该异常是 TimeoutException.您必须增加 Timeout 属性才能让它完成请求，假设将其设置为 4000.

That exception is a TimeoutException. You must increase the Timeout property in order to let it complete the request, let's say to set it to 4000.
