c# - Percent-encoded dot in .NET Uri

Question

I'm trying to send a request to a web service that requires certain . characters in the request URI to be percent-encoded as %2e. I'm having trouble sending a request from .NET, because when I construct the Uri instance it replaces the %2e characters with . characters. How can I work around this issue to send the web request in the form required by the service?

Edit: Here is how I'm constructing the request:

Uri uri = ...;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "GET";
request.Accept = "application/json";
request.UserAgent = "MyUserAgent";

I have attempted the following:

• Constructing the Uri instance using UriTemplate.BindByName

• Constructing the Uri instance, then using UriBuilder to try to insert the %2e characters.

  Uri uri = "...";
  UriBuilder builder = new UriBuilder(uri);
  builder.Path = builder.Path.Replace(".", "%2e");
  uri = builder.Uri;
  

• Constructing the Uri while setting the dontEscape constructor argument to true.
