示例
下面的代码示例获取或设置可以使用 属性进行身份验证的 URI 的 Message 前缀。
public Authorization Authenticate( string challenge,WebRequest request,ICredentials credentials)
{
try
{
string message;
// Check if Challenge string was raised by a site which requires 'CloneBasic' authentication.
if ((challenge == null) || (!challenge.StartsWith("CloneBasic")))

if (credentials is CredentialCache)
{

if (myCredentials == null)
return null;
}
else
{
myCredentials = (NetworkCredential)credentials;
}

// a)Concatenate username and password seperated by space;
// b)Apply ASCII encoding to obtain a stream of bytes;
// c)Apply Base64 Encoding to this array of bytes to obtain our encoded authorization message.

注解
属性 ProtectionRealm 包含属性可用于进行身份验证的 URI 前缀 Message 列表。 WebRequest 及其后代将 URI 与此列表进行比较, Authorization 以确定 是否对特定 URI 有效。
