Console.WriteLine ("The value of 'ContentLength' property after sending the data is {0}", myHttpWebRequest.ContentLength);

// Close the Stream object.
newStream.Close ();

' Set the 'Method' property of the 'Webrequest' to 'POST'.
myHttpWebRequest.Method = "POST"

Console.WriteLine(ControlChars.Cr + "Please enter the data to be posted to the (http://www.contoso.com/codesnippets/next.asp) Uri :")

' Set the content type of the data being posted.
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded"

備註

謹慎

WebRequest、、HttpWebRequest、ServicePointWebClient、和 都已過時，你不應該用它們來做新開發。 請改用 HttpClient。

此 Method 屬性可設定為任一 HTTP 1.1 協定動詞：GET、HEAD、POST、PUT、DELETE、TRACE 或 OPTIONS。

如果 ContentLength 屬性設定為除 -1 以外的任何值，則 Method 必須設定為上傳資料的協定屬性。
