请问VB.net中如何保存BMP/jpg图像

我现在有一个一维数组,byte类型的

如何将这个数组的值生成BMP/jpg图像

我理解你
我写过图片网络传输的和你要求的一样
为了不把图片写到硬盘 又从硬盘读取
而直接保存图片内存流 进行网络传输
从网络读取的图片byte数组转成图片代码如下

Dim mStream As New IO.MemoryStream
mStream.Write(b, 0, b.length) '这里b就是你的一维数组了
Dim Img As New Bitmap(mStream)
mStream.Close()
mStream.Dispose()

下面是把图片保存到一维数组的方法
Dim Stream As New IO.MemoryStream
im.Save(Stream, System.Drawing.Imaging.ImageFormat.Jpeg)
im = Nothing
Stream.Flush()
Dim b As Byte() = Stream.ToArray
Stream.Dispose()

呵呵 我有的啊 private sub command1_click() on error resume next commondialog1.dialogtitle = "打开文件" commondialog1.filter = "所有支持的格式" + _ "(*.bmp;*.jpg;*.gif;*.pcx;*.ico)|" + _ "*.bmp;*.jpg;*.gif;*.pcx;*.ico)" commondialog1.showopen if commondialog1.filename <> "" then if err <> 32755 then dim openfilename as string openfilename = commondialog1.filename picture1.picture = loadpicture(openfilename) end if end if end sub private sub command2_click() on error resume next commondialog1.dialogtitle = "保存为bmp文件" commondialog1.filter = "位图文件(*.bmp)|*.bmp" commondialog1.showsave if commondialog1.filename <> "" then if err <> 32755 then dim savebmpname as string savebmpname = commondialog1.filename savepicture picture1.image, savebmpname end if end if end sub private sub form_load() commondialog1.cancelerror = true end sub 我自己写的啊 很简单的啊
