How write special character (é, è) with StreamWriter?

asp.net, c#, special-characters, streamwriter.write

Solution

Set the encoding for the StreamWriter:

StreamWriter sw = new StreamWriter(webRequest.GetRequestStream(), encoding)

Try this, I hope it helps. It worked for me!

Problem

My problem : I want to write datas with a StreamWriter (my String contains letters é and è) but it doesn't work. Without this letters, it works. The error : Cannot close the stream My code : ``` string postString = "id=" + sIdTransaction + "&nom=" + sNom + "&prenom=" + sPrenom + "&email=" + sEmail + "&adresse.rue=" + sRue + "&adresse.codePostal=" + sCodePostal + "&adresse.ville=" + sVille; string sIdContractant = ""; Encoding iso = Encoding.GetEncoding("utf-8"); Encoding utf8 = Encoding.UTF8; byte[] utfBytes = utf8.GetBytes(postString); byte[] isoBytes = Encoding.Convert(utf8, iso, utfBytes); postString = iso.GetString(isoBytes); string sUrlAuth = "https://test.contralia.fr/Contralia/api/transactions/" + sIdTransaction + "/contractant/"; HttpWebRequest webRequest = CreationRequete(sUrlAuth); webRequest.ContentLength = postString.Length; StreamWriter requestWriter = new StreamWriter(webRequest.GetRequestStream()); requestWriter.Write(postString); requestWriter.Close(); ``` adresse.Ville = Fercé (problem with this é) How can I resolve this problem please ? Thanks
