Recently, WebClient downloaded files in two ways, which are reserved for future inquiry.
Type 1
string URLAddress = @"http://xiazai.ofstack.com";
string receivePath=@"C:\";
client.DownloadFile(URLAddress, receivePath + System.IO.Path.GetFileName(URLAddress));
OK.
Type 2
Stream str = client.OpenRead(URLAddress);
StreamReader reader = new StreamReader(str);
byte[] mbyte = new byte[1000000];
int allmybyte = (int)mbyte.Length;
int startmbyte = 0;
while (allmybyte > 0)
{
int m = str.Read(mbyte, startmbyte, allmybyte);
if (m == 0)
break;
startmbyte += m;
allmybyte -= m;
}
reader.Dispose();
str.Dispose();
string path = receivePath + System.IO.Path.GetFileName(URLAddress);
FileStream fstr = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);
fstr.Write(mbyte, 0, startmbyte);
fstr.Flush();
fstr.Close();
