C#調用C接口字符參數編碼的問題解決方法

1、傳入單字節ANSI字符

[DllImport("hostIO", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]

    public static extern int initHost([MarshalAs(UnmanagedType.LPStr)] string host);

2、傳入雙字節Unicode字符

[DllImport("hostIO", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]
    public static extern int initHost([MarshalAs(UnmanagedType.LPWStr)] string host);
