我编写了一个代码,用于从文件中读取png图像并显示控件.
我想从流和设置读取图像

control.BackgroundImage = Image.FromStream(memStream);

但是当使用这段代码时,会发生"内存不足"异常.但是在使用时

control.Image = Image.FromStream(memStream);

要么

control.BackgroundImage = Image.FromFile(fileSource);

那就是工作.

图像文件大小为5KB.

 if (System.IO.File.Exists(imgSource))
 {
  using (FileStream localFileStream = new FileStream(imgSource, FileMode.Open))
  {
  using (MemoryStream memStream = new MemoryStream())
  {
   int bytesRead;
   byte[] buffer = new byte[1024];

   while ((bytesRead = localFileStream.Read(buffer, 0, buffer.Length)) > 0)
   {
      memStream.Write(buffer, 0, bytesRead);
   }
   retIMG = Image.FromStream(memStream);

   pictureBox1.Image = retIMG;      // is work
   label1.Image = retIMG;       // is work
   button1.Image = retIMG;      // is work
   button1.BackgroundImage = retIMG;    // …
