为什么LOGFONT总是显示null或0

问题描述

我有以下代码:

I have the following code:

[StructLayout(LayoutKind.Sequential)]
        public struct LOGFONT
        {
            public long lfHeight;
            public long lfWidth;
            public long lfEscapement;
            public long lfOrientation;
            public long lfWeight;
            public byte lfItalic;
            public byte lfUnderline;
            public byte lfStrikeOut;
            public byte lfCharSet;
            public byte lfOutPrecision;
            public byte lfClipPrecision;
            public byte lfQuality;
            public byte lfPitchAndFamily;
            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
            public string lfFaceName;

        }
        private void button1_Click(object sender, EventArgs e)
        {
            Font f = new Font("Arial", 12);
            LOGFONT LF = new LOGFONT();
            f.ToLogFont(LF);

        }

不管我使用什么字体名称，LF的所有值都为0，除了lfFaceName为空.看来f.ToLogFont行在调试器中执行，但实际上没有执行任何操作.任何帮助将不胜感激.

and no matter what font name I use all the values of LF are 0 with the exception of lfFaceName which is null. It appears that the f.ToLogFont line executes in the debugger but doesn''t actually do anything. Any help would be greatly appreciated.
