在 .NET Core 上。
示例
下面的代码示例演示如何调用此方法。
void CheckDefaultProxyForRequest( Uri^ resource )
{
WebProxy^ proxy = (WebProxy^)( WebProxy::GetDefaultProxy() );
// See what proxy is used for resource.
Uri^ resourceProxy = proxy->GetProxy( resource );
// Test to see whether a proxy was selected.
if ( resourceProxy == resource )
{
Console::WriteLine( "No proxy for {0}", resource );
}
else
{
Console::WriteLine( "Proxy for {0} is {1}", resource,
resourceProxy );
}
}
public static void CheckDefaultProxyForRequest(Uri resource)
{
WebProxy proxy = (WebProxy) WebProxy.GetDefaultProxy();
// See what proxy is used for resource.
Uri resourceProxy = proxy.GetProxy(resource);
// Test to see whether a proxy was selected.
if (resourceProxy == resource)
{
Console.WriteLine("No proxy for {0}", resource);
}
else
{
Console.WriteLine("Proxy for {0} is {1}", resource.ToString(),
resourceProxy.ToString());
}
}
注解
方法 GetDefaultProxy 读取 Internet Explorer 5.5 及更高版本存储的非动态代理设置,并使用这些设置创建实例 WebProxy 。
方法 GetDefaultProxy 不会从 Internet Explorer 运行的脚本、自动配置条目或 DHCP 或 DNS 查找获取任何动态设置。
应用程序应使用 HttpClient.DefaultProxy 属性而不是 GetDefaultProxy 方法。
注意
.NET Core 不支持此属性。
