如何将位图转换为图标 [英] How to convert bitmap to icon

问题描述

我将我的图像从picturebox存储到数据库

但是在我加载了我的datagrod视图列之后，由于图片大而得到的图像非常大，所以我想将我的位图存储为图标怎么做这个

这是我的代码

  if （picFoto.Image！=  null ）
 {
位图bmp =  new 位图（picFoto.Image）; 
  ///   / Icon icon = System.Drawing.Icon.FromHandle（bmp.GetHicon（））; 
  
 System.IO.MemoryStream imgMemoryStream =  new  System.IO.MemoryStream（）; 
 bmp.Save（imgMemoryStream，System.Drawing.Imaging.ImageFormat.Jpeg）; 
  byte  [] imgByteData = imgMemoryStream.GetBuffer（）; 
 
 row [  Foto] = imgByteData; 
 
} 

解决方案

看看这个：

1. 一个简单的类，可以将图像转换为c＃中的图标 [ ^ ]

2. 使用C＃将图像文件转换为图标 [ ^ ]

我认为你的意思是你要生成缩略图而不是图标

在MSDN网站上查看这篇文章如何：创建缩略图 [ ^ ]

解决方案

Check this out:
1. A simple class that converts a image to a icon in c# [^]
2. Convert Image file to Icon using C#[^]

I think you mean you want to generate a thumbnail image rather than an icon
Have a look at this article on the MSDN website How to: Create Thumbnail Images[^]
