Using HTTP Authentication with a C# WebRequest

问题

I want to make a web request to a page that needs authenticating. How would I go about doing this? I found something that said possibly to use the Credentials property, but I'm not sure how to use it.

回答1:

Assign a new NetworkCredential instance to the Credentials property:

webClient.Credentials = new NetworkCredential("Mehrdad", "Password");

回答2:

Basic auth example:

public void SetBasicAuthHeader(WebRequest req, String userName, String userPassword)
{
    string authInfo = userName + ":" + userPassword;
    authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
    req.Headers["Authorization"] = "Basic " + authInfo;
}

It is also possible to authenticate automatically with. This will use the credentials of the currently logged on user.

webClient.Credentials = CredentialCache.DefaultCredentials
