C#实现jpg转MemoryStream，再转成bmp保存

Java中应该思路差不多。

static void Main(string[] args)
{
string picPath = @"D:\download\Pic.jpg";//Origin picture path as jpg
string destPath = @"D:\download\Pic2.bmp";//Destination picture as bmp(or any type u like)
Image img = Image.FromFile(picPath);//load origin picture
File.Create(destPath);//create dest picture as path u want
using(MemoryStream memStream=new MemoryStream())//create a instance of memorystream
{
img.Save(memStream, ImageFormat.Bmp);//save stream from origin pic as format bmp
Bitmap destBmp = new Bitmap(memStream);//create bmp instance from stream above
destBmp.Save(destPath);//save bmp to the path you want
}
Console.WriteLine("**********Done**************");
Console.ReadKey();
}

兄弟，没有看懂哦

这代码应该可以用,你要问什么?

这段代码有问题吗？

using system.io;
