c# - 如何释放 BitMap 类持有的文件

Question

我有以下代码:

Bitmap image = new Bitmap(filePath);
...
image.Save(someOtherPath);
image.Dispose();
File.Delete(filePath);
File.Move(someOtherPath, filePath);

File.Delete 行引发以下错误:

The process cannot access the file '...' because it is being used by another process.

如何让 C# 释放它对文件的锁定？

Answer 1

尝试

using(var image = new Bitmap(filepath))
{
    image.Save(someOtherPath);
}


File.Delete(filePath);
File.Move(someOtherPath, filePath);
