[討論] google api qrcode轉存圖片<研究出來了..>
各位好...
最近才開始學習寫C#
還請各位幫忙給我一點建議，謝謝了
目前是寫一個WEB FORM 用C#
=====================================================================
然後碰到的問題是：
我利用了GOOGLE API 產生出來的QRCODE，該怎麼樣能夠轉存到我的資料夾裡呢?
<註解後面的是參考GOOGLE出來的資料自己的測試...>
再麻煩各位大大
辛苦各位了

HttpWebResponse rsp = (HttpWebResponse)req.GetResponse();
if (rsp.StatusCode == System.Net.HttpStatusCode.OK)

this.Image1.ImageUrl = strQRcode;
================================以下為參考後的個人測試======================
// 測試抓取 Google Logo.
Uri uri = new Uri(strQRcode);
string saveDir =
@"D:\ASPNET\WebApplication1\WebApplication1\NewFolder1\"; // 注意：資料夾必須
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));

WebClient mywebclient = new WebClient();
