復(fù)制代碼 代碼如下:
<head runat="server">
<title></title>
<script src="jquery-1.7.1.js" type="text/javascript"></script>
<script type="text/javascript">
function ShowP(obj) {
$("#Image1")[0].src = "ShowPic.aspx?URL=" + obj.id;
}
</script>
</head>
<body>
<form runat="server">
<div>
<input type="button" value="button" />
<asp:Image runat="server" />
</div>
</form>
</body>
</html>
復(fù)制代碼 代碼如下:
public partial class ShowPic : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
#region "根據(jù)照片路徑，將照片轉(zhuǎn)為二進(jìn)制數(shù)組"
string strUrl = Request.QueryString["URL"];
// 以二進(jìn)制方式讀文件
FileStream aFile = new FileStream(strUrl, FileMode.OpenOrCreate, FileAccess.ReadWrite);
// 創(chuàng)建一個(gè)二進(jìn)制數(shù)據(jù)流讀入器，和打開(kāi)的文件關(guān)聯(lián)
BinaryReader brMyfile = new BinaryReader(aFile);
// 把文件指針重新定位到文件的開(kāi)始
brMyfile.BaseStream.Seek(0, SeekOrigin.Begin);
//獲取照片的字節(jié)數(shù)組
byte[] photo = brMyfile.ReadBytes(Convert.ToInt32(aFile.Length.ToString()));
// 關(guān)閉以上new的各個(gè)對(duì)象
brMyfile.Close();
#endregion
Response.BinaryWrite(photo);
}
}
