Answer 1

翻译成C#.net Web，谢谢了！

Answer 2

似乎是要用某个股票网站提供的service...

Answer 3

byte[] ImaByte;
            ImaByte = webService.getStockImageByteByCode(textBox1.Text);
            Image tempImage;
            Stream imageStream = new MemoryStream(ImaByte);
            //imageStream.Read(ImaByte, 0, ImaByte.Length);
            tempImage = Image.FromStream(imageStream);
            pictureBox1.Image = tempImage;
            pictureBox1.Show();
其实就是这儿不知道怎么写成C#.net Web的形式

Answer 4

分两个文件：index.aspx:
<img src="StockImage.aspx?StockCode=<%=textBox1.Text%>" />
StockCode.aspx:
<%
string StockCode = Request.QueryString("StockCode").Trim();
if (StockCode == string.Empty)
{
  Response.WriteFile("NullStock.gif");
}
else
{
  byte[] ImaByte = webService.getStockImageByteByCode(StockCode);
  Response.BinaryWrite(ImaByte);
}
%>
