c# - HttpWebResponse 返回 404 错误

Question

如何让Httpwebresponse忽略404错误继续处理？这比在输入中查找异常更容易，因为这种情况很少发生。

Answer 1

我假设您的代码中某处有一行，例如:

HttpWebResponse response = request.GetResponse() as HttpWebResponse;

只需将其替换为:

HttpWebResponse response;

try
{
    response = request.GetResponse() as HttpWebResponse;
}
catch (WebException ex)
{
    response = ex.Response as HttpWebResponse;
}
