报错的是 因为System.IO.Path.GetFileName(URLAddress) 返回的字符串 带有非法字符 ‘？’
string URLAddress = @"http://translate.google.cn/translate_tts?ie=UTF-8&q=你好&tl=zh-CN&total=1&idx=0&textlen=9&prev=input";
string receivePath = @"C:\";
System.Net.WebClient client = new System.Net.WebClient();
string p=System.IO.Path.GetFileName(URLAddress);
foreach (var element in Path.GetInvalidFileNameChars()) {
p=p.Replace(element,'_');
}
client.DownloadFile(URLAddress, receivePath + p));
追问
