[Asp.Net] 資料庫存圖片與讀圖片

 常用基本功能： 
利用ASP.NET的FileUpload上傳Binary資料的圖片,存放在Image欄位型態的資料庫裡,並且結合ashx handler來瀏覽圖片


using System;
using System.Web;
using System.Data;

public class movieimg : IHttpHandler {
   
    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "image/jpeg";
        if (context.Request["mid"] != null)
        {
            Select_Object.GetMovieImage gmi =
                new Select_Object.GetMovieImage(context.Request["mid"]);
            DataTable img = gmi.GetData();
            if (img != null)
            {
                context.Response.BinaryWrite((byte[])img.Rows[0][0]);
            }
        }
        //context.Response.Write("Hello World");
    }

    public bool IsReusable {
        get {
            return false;
        }
    }

}
