推荐答案

发生了什么:某些进程打开文件以进行独占访问(不允许共享)，这是默认模式.尝试从您的进程中打开同一文件失败，但会看到异常.此异常的类型为System.IO.IOException.不幸的是，该异常不包含保存文件的进程的句柄.

在保存文件的进程退出之前，无法进行任何操作.您可以终止此过程；这就是您所能做的.

您可以使用System.Diagnostics.Process.GetProcesses枚举所有进程来获取有问题的进程的句柄.使用枚举期间获得的Process实例以某种方式确定您需要的过程.您将获得该流程的实例.使用Process.Kill终止它.

这种方式是有问题的，因为没有用于识别过程的通用标准.您只需要打开文件的过程.您可以使用System.Management进行操作.方法如下:

What happens: some process opens the file for exclusive access (sharing not allowed) which is the default mode. An attempt to open the same file from your process fails with the exception you observe. The type of this exception is System.IO.IOException. Unfortunately, the exception does not contain the handle of the process holding the file.

Nothing can be done until the process holding the file exits. You can terminate this process; this is all you can do.

You can get the handle of the offending process by enumerating all the processes using System.Diagnostics.Process.GetProcesses; somehow identify the process you need using the instance of the Process obtained during enumeration. You will get the instance of the process. Use Process.Kill to terminate it.

This way is problematic because there is no a universal criterion used to identify the process. You need only the process which has opened your file. You can do it using System.Management. Here is how:
