Question

I need to read the HTTP Response 200 OK with the following text/plain body. (Either one)

OK

NUMBER NOT IN LIST

ERROR

But I only know how to read the HTTP Response but not the response body. Explanation with example would be much appreciated

Answer 1

You can use the WebClient.DownloadString Method to make an HTTP GET request and get the HTTP response body as string returned:

using (var client = new WebClient())
{
    string result = client.DownloadString("http://example.com/path/to/file");

    switch (result)
    {
        case "OK":
        case "NUMBER NOT IN LIST":
        case "ERROR":
            break;
    }
}
