Here is what you can do:

1- Create a web page like http://www.test.com/default.aspx

2- Pass a querystring parameter like http://www.test.com/default.aspx?textboxvalue=123

3- In the Page_load of the default.aspx assign the query string value to the webpage textbox

4- Call the webpage from the your application like

WebClient client = new WebClient();
 String url=@"www.test.com/default.aspx?textboxvalue=" + [Your textbox value]
  Stream data = client.OpenRead(url);

EDIT:

If you donot have the access to the code then you are probably looking to automate the webpage. To automate you can use the http://watin.org/.

Here is the sample code

using (var browser = new IE("http://www.google.com"))
  {
    browser.TextField(Find.ByName("q")).TypeText("WatiN");
    browser.Button(Find.ByName("btnG")).Click();

    Assert.IsTrue(browser.ContainsText("WatiN"));
  }
