How Can I Make HTTP GET Requests with URL-Encoded Slashes in .NET?

HTTP GET Requests with URL-Encoded Slashes

Accessing URLs with URL-encoded slashes in .NET poses a challenge. Instead of preserving the URL encoding, the framework attempts to canonicalize it, resulting in an invalid HTTP request.

To overcome this issue, a workaround exists:

Uri uri = new Uri("http://example.com/%2F");
ForceCanonicalPathAndQuery(uri);
using (WebClient webClient = new WebClient())
{
  webClient.DownloadData(uri);
}

void ForceCanonicalPathAndQuery(Uri uri){
  string paq = uri.PathAndQuery;
  FieldInfo flagsFieldInfo = typeof(Uri).GetField("m_Flags", BindingFlags.Instance | BindingFlags.NonPublic);
  ulong flags = (ulong) flagsFieldInfo.GetValue(uri);
  flags &= ~((ulong) 0x30);
  flagsFieldInfo.SetValue(uri, flags);
}

This hack manipulates internal URI flags to maintain the URL encoding, allowing HTTP GET requests with URL-encoded slashes. However, it should be noted that this approach may not be compatible with future framework versions.
