using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Imaging;
using System.IO;namespace test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private byte[] photo;
        private void Form1_Load(object sender, EventArgs e)
        {
            //Image img = new Bitmap(@"C:\Documents and Settings\All Users\Documents\My Pictures\示例图片\Sunset.jpg");
            Image img = new Bitmap(@"D:\065_045.jpg");
            MemoryStream stream = new MemoryStream();
            img.Save(stream, ImageFormat.Bmp);
            BinaryReader br = new BinaryReader(stream);
            photo = stream.ToArray();
            stream.Close();
        }        private void button1_Click(object sender, EventArgs e)
        {
            byte[] bytes = photo;
            MemoryStream ms = new MemoryStream(bytes);
            ms.Position = 0;
            Image img = Image.FromStream(ms);
            ms.Close();
            this.pictureBox1.Image = img;
             img.Dispose();              
        }        private void button2_Click(object sender, EventArgs e)
        {
            byte[] bytes = photo;
            FileStream fs = new FileStream(@"D:\tupian.bmp", FileMode.Create, FileAccess.Write);
            fs.Write(bytes, 0, bytes.Length);
            fs.Flush();
            fs.Close();
    
        }       
    }
}
这是我的程序

Answer 2

调试代码即可知道另，尽量使用 .Dispose() ，不用.Close() 释放资源才足

错误 2 “GenerateResource”任务意外失败。
System.OutOfMemoryException: 内存不足。
   在 System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement, Boolean validateImageData)

这个是提示的错误！各位大侠帮忙看看吧！

Answer 4

RGB 8：8：8 未压缩 
6000*6000*256*256*256/1024/1024/1024/8=70312.5G

Answer 5

fs.Write(bytes, 0, bytes.Length); 看看 Length是多少。
