如何删除分配给PictureBox xontrol的图像文件？ [英] How to delete an image file assigned to a PictureBox xontrol ?

问题描述

在Windows窗体应用程序中，某些图像文件被分配给PictureBox控件。我想删除那些图像文件。第一种方法[1]带有"Image.FromFile"。给出了"另一个进程正在使用该图像文件"的错误消息，尽管"Image.Dispose（）"也是如此。执行
。第二种方法[2]使用"Image.FromStream";如果"fs.Close（）"，则为PictureBoxes和Buttons的结果（X）图像。是的。如果没有"fs.Close（）"，它会给出"另一个进程正在使用..."的相同错误消息。如何正确显示图像
并删除这些图像文件？

In a Windows form application, some image files are assigned to PictureBox controls. I am trying to delete those image files. The first approach [1] with "Image.FromFile" gives an error message of "Another process is using this image file", although "Image.Dispose()" is executed. The second approach [2] using "Image.FromStream" results (X) images for PictureBoxes and Buttons, if "fs.Close()" is inclided. Without "fs.Close()", it gives the same error message of "Another process is using...". How can I display images properly and delete those images files ?

谢谢

pictureBoxSelected.Image.Dispose（）;

pictureBoxSelected.Image.Dispose();
pictureBoxSelected.Image = Image.FromFile(@tempImage);

}

[2]

FileStream fs = new FileStream （fileName，FileMode.Open，FileAccess.Read）;
$
pictureBox.Image = System.Drawing.Image.FromStream（fs）;

fs.Close（）;

FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read);
pictureBox.Image = System.Drawing.Image.FromStream(fs);
fs.Close();

您好，

如果您使用picturebox的ImageLocation属性，则可以使用相同的属性设置图片，您可以获得图片路径...

If you use ImageLocation property of picturebox you can then set picture also using same property you can get Picture path...

  pictureBox1.ImageLocation = @" c：\ pic。 jpg";

 pictureBox1.ImageLocation = @"c:\pic.jpg";
