检查2个本地和网络路径是否将客户端PC中的同一文件夹作为目标

Question

背景

我正在使用多用户软件，其中每个用户都必须在同一文件夹中创建Excel文件。

要求

用户必须选择所有文件的保存路径。

问题

现在，问题在于在数据库中，仅保存local path of Server，由于某种技术原因无法保存其网络路径。

问题

如何检查服务器的本地路径和用户选择的路径（服务器的网络路径）是否定位到客户端PC上服务器PC 中的同一文件夹？

OR

如何检查是否：-

1. 服务器的本地路径和用户选择的路径（服务器的网络路径）将服务器PC
2. 必须从客户端PC
检查以上条件

我尝试过的事情

我已经从Internet上挽救了此代码，如果您在 SERVER-PC 上，则可以检查 本地和网络路径是否以同一文件夹为目标 ，方法是调用 IsTargetingSameDirectory 函数。

    }

    private static BY_HANDLE_FILE_INFORMATION? MY_GetFileInfo(SafeFileHandle directoryHandle)
    {
        BY_HANDLE_FILE_INFORMATION objectFileInfo;
        if ((directoryHandle == null) || (!GetFileInformationByHandle(directoryHandle.DangerousGetHandle(), out objectFileInfo)))
        {
            return null;
        }
        return objectFileInfo;
    }

    public static bool IsTargetingSameDirectory(string dirName1, string dirName2)
    { //
        bool bRet = false;
        //NOTE: we cannot lift the call to GetFileHandle into GetFileInfo, because we _must_
        // have both file handles open simultaneously in order for the objectFileInfo comparison
        // to be guaranteed as valid.
        using (SafeFileHandle directoryHandle1 = MY_GetFileHandle(dirName1), directoryHandle2 = MY_GetFileHandle(dirName2))
        {
            BY_HANDLE_FILE_INFORMATION? objectFileInfo1 = MY_GetFileInfo(directoryHandle1);
            BY_HANDLE_FILE_INFORMATION? objectFileInfo2 = MY_GetFileInfo(directoryHandle2);
            bRet = objectFileInfo1 != null
                    && objectFileInfo2 != null
                    && (objectFileInfo1.Value.FileIndexHigh == objectFileInfo2.Value.FileIndexHigh)
                    && (objectFileInfo1.Value.FileIndexLow == objectFileInfo2.Value.FileIndexLow)
                    && (objectFileInfo1.Value.VolumeSerialNumber == objectFileInfo2.Value.VolumeSerialNumber);
        }
        return bRet;
    }

但是问题在于，我必须从远程或客户端PC 而不是服务器PC 本身中找到它。
