如果用HttpWebRequest和HttpWebResponse从服务器取图片,会触发图片变化.于是想到从IE缓存读取图片 参考https://www.cnblogs.com/yelaiju/archive/2010/10/01/1839860.html和https://blog.csdn.net/annkie/article/details/6065521和http://www.mamicode.com/info-detail-370382.html 代码如下: using System;
写入图片部分代码:假设图片为 test.gifbyte [] bytes = File.ReadAllBytes(@"c:\test.gif");SqlConnection con = new SqlConnection("server=.;uid=sa;pwd=xxx;database=数据库名");con.open();SqlCommand cmd = new SqlCommand("insert into 表(图片字段) values(@image)
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Drawing; using System.Drawing.Imaging; using System.Collections; namespace YEMLWEB.AppHelper { public class Picturexif { #region 构造函数 /// <summary> ///
本例子的目的在于测试往oracle数据库中插入blob字段 //以下代码源于:https://www.cnblogs.com/ywlx/p/4544179.html public static String getImgStr(String imgFile){ //将图片文件转化为字节数组字符串,并对其进行Base64编码处理 InputStream in = null; byte[] data = null; //读取图片字节数组 try { in = new FileInputStream(
