c# WebClient下载问题

Question

url结尾 input 就报错
换成结尾url txt zip rar 都是可以的....
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();
client.DownloadFile(URLAddress, receivePath + System.IO.Path.GetFileName(URLAddress));

Answer 1

client.DownloadFile(URLAddress, receivePath + System.IO.Path.GetFileName(URLAddress));不知道你为什么这么写
你传入的根本就不是合法的文件路径，你能说说你的意图么？
