Question

我正在调用这行代码来访问azure服务器：

var request = (HttpWebRequest)WebRequest.Create(uri);

并收到此例外。有人知道如何管理吗？

虽然我们有不同的调用堆栈，但此解决方案有助于HttpClient request throws IOException。

您需要在注册表中创建这些密钥。

路径：HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ .NETFramework

关键：

名称：＆＃34; LegacyWPADSupport＆＃34;输入：＆＃34; dword＆＃34;数据：00000000

路径：HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Microsoft \ .NETFramework

关键：

名称：＆＃34; LegacyWPADSupport＆＃34;输入：＆＃34; dword＆＃34;数据：00000000

WebRequest.Create抛出IOException“指定的注册表项不存在。”
