HttpWebRequest URL Output

Question

I know the name sounds like this issue has been examined many times. But I am struggling with a specific case, and I am very confused about this. Hopefully experienced C # 'er could point me in the right direction.

I have a code:

string serviceURL = "https://www.domain.com/service/tables/bucketname%2Ftables%2Ftesttable/imports";
HttpWebRequest dataRequest = (HttpWebRequest)WebRequest.Create(serviceURL);

Now when I read dataRequest, I see the following:

RequestUri: {https://www.domain.com/service/tables/bucketname/tables/testtable/imports}

And it looks like HttpWebRequest has changed %2Fto /. However, the server requires that the requested Uri be exactly the same as the serviceURL containing is written %2F.

Is there a way to get the HttpWebRequest class to call Url:

https://www.domain.com/service/tables/bucketname%2Ftables%2Ftesttable/imports

Many thanks! Here I have a complete loss ... -Brett

Answer 3

string serviceURL = Uri.EscapeUriString("https://www.domain.com/service/tables/bucketname%2Ftables%2Ftesttable/imports");
