推荐答案

我无法看到你提供的图片您的查询。据我所知，您的系统不知道该消息已被读取。因此，首先，您必须让您的系统了解您已阅读邮件。为此，您可以在数据库中拥有另一列，每条消息的默认值为未读消息;单击该消息进行读取后，将该列的值更新为读取消息。针对网格中的两个值显示适当的图像。而不是字符串消息，更好地以布尔值的形式存储这些值。如果邮件未读，则为false，否则为true。并且立即更新缓存/内存中的值，以便您可以在整个应用程序中对每条消息具有真实值。

I was unable to see the image you have provided along with your query. As far as I have understood, your system doesn't know that the message has been read. So, first you have to make your system understand that you have read a message. For that you can have another column in your database with a default value of 'unread message' against each message; once you click on that message to read it, update that column's value to 'read message'. Show appropriate images against both values in the grid. Instead of a string message, better store these values in the form of boolean value. If a message is unread, it is false, otherwise true. And yes update your values in the cache/memory instantly so that you can have the true value against each message throughout the application.

FileInfo image = new FileInfo(context.Server.MapPath("~/Product_Images/Image-under-update.gif"));
string image1 = image.ToString();
byte[] buffer = File.ReadAllBytes(image1);
// here you will get binary data which you can insert into database
context.Response.BinaryWrite(buffer);
