Detect proxy setting on webrequest

Good afternoon my dear, I need to make a request for an api that is in a domain outside the local network, I do this through a webrequest that was created this way:

WebRequest myWebRequest = WebRequest.Create("urldestino");

However, the network has a proxy, which blocked my requests stating that proxy authentication was required. To test the operation, I was able to perform the request by setting the proxy manually as follows:

WebProxy myProxy = new WebProxy();
myProxy = (WebProxy)WebProxy.GetDefaultProxy();
myProxy.Credentials = new NetworkCredential("meuusuario", "minhasenha", "meudominio");
myWebRequest.Proxy = myProxy;

Detail: After running "myProxy = (WebProxy)WebProxy.GetDefaultProxy();" myProxy.Credentials got null, so I set it manually.

In this way, the request passes through the proxy, however, I was directed to get the proxy session already authenticated by windows, in the same way that browsers and postman does, in postman for example I make the request without the need of inform the proxy data and it does not return me a proxy authentication is required.

Is there any way I can get the authenticated proxy session, without having to manually enter the user's registration and password?

Thank you very much in advance.

To avoid passing the credentials manually you can obtain the credentials as follows:

WebProxy myProxy = new WebProxy();
myProxy = (WebProxy)WebProxy.GetDefaultProxy();
myProxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
myWebRequest.Proxy = myProxy;

With System.Net.CredentialCache.DefaultCredentials; it will return the credentials already set in IE by default, just below you arrow to webrequest.proxy the credentials.
