Question

我想使用kernel32.dll下的GetFileInformationByHandle函数来获取NTFS唯一文件标识符。函数声明是这样的：

Declare Auto Function GetFileInformationByHandle Lib "kernel32.dll" _ 
(ByVal hFile As IntPtr, ByRef lpFileInformation As BY_HANDLE_FILE_INFORMATION) As Boolean

我的问题可能听起来很愚蠢但是，如何在visual basic中获取给定文件名的文件句柄（hFile As IntPtr）？

您可以使用FileStream.SafeFileHandle属性：

Using fs As FileStream = New FileStream("c:\test.txt", FileMode.Create, FileAccess.Write)
    Dim hFile = fs.SafeFileHandle.DangerousGetHandle()
    ' do something
End Using

如何在vb .net中获取文件句柄
