Java中DataOutputStream.writeUTF(String)在c#中的替代

java

public static String webPost(String msg,String myurl){

String ret = "";

HttpURLConnection conn = null;

DataOutputStream dos = null;

DataInputStream dis = null;

try {

URL url = new URL(myurl);

conn = (HttpURLConnection)url.openConnection();

conn.setDoOutput(true);

conn.setRequestMethod("POST");

dos = new DataOutputStream(conn.getOutputStream());

dos.writeUTF(msg);

dos.flush();



int code = conn.getResponseCode();

System.out.println("code " + code);

if (code == HttpURLConnection.HTTP_OK){

dis = new DataInputStream(conn.getInputStream());

ret = dis.readUTF();

// System.out.println(ret);

}

// conn.disconnect();

}catch (Exception e) {

e.printStackTrace();

}finally{

if (dis != null)

{

try {

dis.close();

} catch (IOException e) {

e.printStackTrace();

}

}

if (dos != null)

{

try {

} catch (IOException e) {

e.printStackTrace();
