我希望将一个图片jpeg,gif等文件上传到updateprofilepicture页面上的SQL数据库中.然后在配置文件页面上,我想从sql数据库中检索图像并将其显示在Asp: Image控件中.我有很多代码尝试这样做,但
// ProcessRequest method of Image.ashx
long imageId = Convert.ToInt64(Request.QueryString["ImageId"]);
using (var conn = new SqlConnection(connectionString))
using (var command = new SqlCommand(
"SELECT ImageFile FROM ImageTable WHERE ImageId = @ImageID", conn))
{
command.Parameters.Add("@ImageID", SqlDbType.Int).Value = imageId;
conn.Open();
Response.ContentType = "image/gif";
Response.BinaryWrite((byte[]) command.ExecuteScalar());
}
然后在您的页面中使用图像:
<asp:Image id="Image1" runat="server" ImageUrl="Image.ashx?ImageID=12"/>
