如何將此字符串解碼爲utf-8字符串？

Question

我有這樣的代碼：

string URL = "http://translate.google.com/m?hl=vi&sl=en&tl=vi&ie=UTF-8&prev=_m&q=song"; 
string s = ""; 
WebClient client = new WebClient(); 
client.Headers.Add("user-agent", "Mozilla/5.0 (SymbianOS/9.4; U; Series60/5.0 Nokia5800d-1/21.0.025; Profile/MIDP-2.1 Configuration/CLDC-1.1) AppleWebKit/413 (KHTML, like Gecko) Safari/413"); 
s = client.DownloadString(URL); 

在運行時我收到了字符串格式字符串：

danh tÆ°Ì€ buổi há»p để ca hát 

這個字符串：

danh từ buổi họp để ca hát 

非常感謝你:)

當得到byte[]代表一個stri ng，你需要知道在獲取之前使用了什麼編碼。

在這種情況下，它是UTF-8，因此設置的WebClient，以導致正確的字符串的Encoding：

string URL = "http://translate.google.com/m?hl=vi&sl=en&tl=vi&ie=UTF-8&prev=_m&q=song"; 
string s = ""; 
WebClient client = new WebClient(); 
client.Encoding = Encoding.UTF8; 
client.Headers.Add("user-agent", "Mozilla/5.0 (SymbianOS/9.4; U; Series60/5.0 Nokia5800d-1/21.0.025; Profile/MIDP-2.1 Configuration/CLDC-1.1) AppleWebKit/413 (KHTML, like Gecko) Safari/413"); 
s = client.DownloadString(URL);
