时间Thu Jul 29 20:45:52 2010
各位好...
最近才开始学习写C#
还请各位帮忙给我一点建议，谢谢了
目前是写一个WEB FORM 用C#
=====================================================================
然後碰到的问题是：
我利用了GOOGLE API 产生出来的QRCODE，该怎麽样能够转存到我的资料夹里呢?
<注解後面的是参考GOOGLE出来的资料自己的测试...>
再麻烦各位大大
辛苦各位了

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strQRcode);
HttpWebResponse rsp = (HttpWebResponse)req.GetResponse();
if (rsp.StatusCode == System.Net.HttpStatusCode.OK)
{
this.Image1.ImageUrl = strQRcode;
================================以下为参考後的个人测试======================
// 测试抓取 Google Logo.
Uri uri = new Uri(strQRcode);
string saveDir =
@"D:\ASPNET\WebApplication1\WebApplication1\NewFolder1\"; // 注意：资料夹必须
已存在
string fileName = "google.png";
string savePath = saveDir + fileName;
System.Net.WebRequest request =
System.Net.WebRequest.Create(uri);
System.Net.WebResponse response = request.GetResponse();
System.IO.Stream stream = response.GetResponseStream();
Image img = Image.FromStream(stream);
img.Save(savePath);
////image1.Saveas(Server.MapPath(@"~\NewFloder1\"+
TextBox2.Text));
////Image1.ImageUrl.ToString();
////Image1.ImageUrl.GetTypeCode.SaveAs(Server.MapPath(@"~\PhotoDate\" +
FileUpload1.FileName))
//System.Net.WebClient WC = new System.Net.WebClient();
//System.IO.MemoryStream Ms = new
System.IO.MemoryStream(WC.DownloadData(strQRcode));
//Image1 img = image.FromStream(Ms);
//img.Saveas(Server.MapPath(@"~\NewFloder1\"+
TextBox2.Text));

rsp.Close();
辛苦各位了...感激!
