进程无法访问文件 [英] process cannot access file

问题描述

您好

我想删除以前使用BitmapImage访问的图像文件.
像这样:

hello

I want do delete an image-file i accessed before with a BitmapImage.
Like this:

BitmapImage bi = new BitmapImage();
bi.BeginInit();
bi.UriSource = new Uri(@"c:\test.jpg", UriKind.RelativeOrAbsolute);
bi.EndInit();

System.IO.File.Delete(@"c:\test.jpg");

File.Delete引发以下异常:
"System.IO.IOException:进程无法访问文件"C:\ test.txt".因为它正在被另一个进程使用."

我如何告诉WPF释放文件以便可以将其删除?

wpfnoob

File.Delete throws the following exception:
"System.IO.IOException: The process cannot access the file "C:\test.txt" because it is being used by another process."

How can i tell WPF to free the file so i can delete it?

bi.UriSource = Uri ( UriKind .RelativeOrAbsolute);

bi.UriSource = new Uri(@"c:\test.jpg", UriKind.RelativeOrAbsolute);

bi.EndInit();

System.IO. File .Delete( @"c:\ test.jpg"");

System.IO.File.Delete(@"c:\test.jpg");
