皆さん、
お疲れ様です。
下記に代替データストリーム取得C#ソースをvb.netへ変換したいんです。お願い致します。変換するToolを使いましたが上手く動かないです。問題あるやつは
[DllImport("kernel32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool BackupRead(SafeFileHandle hFile, IntPtr lpBuffer, uint nNumberOfBytesToRead, out uint lpNumberOfBytesRead, [MarshalAs(UnmanagedType.Bool)] bool bAbort, [MarshalAs(UnmanagedType.Bool)] bool bProcessSecurity,
ref IntPtr lpContext);
ここです。

C#からvb.netへ変換したい
