我要用java的借口发短信，请问下面的代码用C#怎么翻译过来

[不同凡响]

JAVA不是很熟。请各位高人帮帮忙。

代码如下：
public static String get(String address, int timeOut) throws IOException {
String ret = "";
URL url = new URL(address);
URLConnection connection = url.openConnection();
connection.setConnectTimeout(timeOut);
connection.setReadTimeout(timeOut);
connection.setDoOutput(true);
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) {
ret = ret + inputLine;
}
in.close();
in = null;
url = null;

ret = ret.trim();

return ret;
}
