利用XMLHTTP下载文件,和以前的方法一样,先添加引用-COM-MicrosoftXml3.0,然后在代码开始处写:
usingMSXML2;
下面就是主要的代码:
privatevoidPage_Load(objectsender,System.EventArgse){
stringUrl="http://dotnet.aspx.cc/Images/logoSite.gif";
stringStringFileName=Url.Substring(Url.LastIndexOf("/")+1);
stringStringFilePath=Request.PhysicalApplicationPath;
if(!StringFilePath.EndsWith("/"))
StringFilePath+="/";
MSXML2.XMLHTTP_xmlhttp=newMSXML2.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.FileStreamfs=newSystem.IO.FileStream(StringFilePath+StringFileName,System.IO.FileMode.CreateNew);
System.IO.BinaryWriterw=newSystem.IO.BinaryWriter(fs);
w.Write((byte[])_xmlhttp.responseBody);
w.Close();
fs.Close();
Response.Write("文件已经得到。<br><ahref='"+Request.ApplicationPath+StringFileName+"'target='_blank'>");
Response.Write("查看"+StringFileName+"</a>");
}
else
Response.Write(_xmlhttp.statusText);Response.End();}
