该进程无法访问该文件,因为该文件正由另一个进程使用.File.Copy

Question

我正在尝试将png文件复制到我的项目文件夹的一部分,但是当我尝试时,我得到了这个错误.

该进程无法访问文件'....../Image.png',因为它正由另一个进程使用.

我可以向你保证没有其他程序正在访问该文件,我所有的winforms设计器窗口都关闭,以及任何其他应用程序或窗口.

这是我正在使用的代码,我已经在这个网站上尝试了所有其他答案,没有任何作用,任何有关此的帮助将不胜感激!

您似乎正在将文件复制到其上.

string newFileName = openFileDialog1.FileName;

string filename = openFileDialog1.FileName;

File.Copy(filename, newFileName, true);
