在.NET中利用XMLHTTP下载文件
string Url = "http://dotnet.aspx.cc/Images/logoSite.gif";
string StringFileName = Url.Substring(Url.LastIndexOf("/") + 1);
string StringFilePath = Request.PhysicalApplicationPath;
if (!StringFilePath.EndsWith("/"))
{
StringFilePath += "/";
}
MSXML2.XMLHTTP _xmlhttp = new MSXML2.XMLHTTPClass();
_xmlhttp.open("GET", Url, false, null, null);
_xmlhttp.send("");
if (_xmlhttp.readyState == 4)
{
if (System.IO.File.Exists(StringFilePath + StringFileName))
{
System.IO.File.Delete(StringFilePath + StringFileName);
}
System.IO.FileStream fs = new System.IO.FileStream(StringFilePath + StringFileName, System.IO.FileMode.CreateNew);
System.IO.BinaryWriter w = new System.IO.BinaryWriter(fs); w.Write((byte[])_xmlhttp.responseBody);
w.Close();
fs.Close();
Response.Write("文件已经得到。<br><a href='" + Request.ApplicationPath + StringFileName + "' href_cetemp='" + Request.ApplicationPath + StringFileName + "' target='_blank'>");
Response.Write("查看" + StringFileName + "</a>");
}
else Response.Write(_xmlhttp.statusText);
Response.End();
