在。net中怎样调用MFC中的方法CFont::CreatePointFont

[curdle]

我想调用MFC中CFont::CreatePointFont方法，创建自己的字体，如何调用？

[lookfeng]

这是C==实现：
BOOL CFont::CreatePointFont(int nPointSize, LPCTSTR lpszFaceName, CDC* pDC)
{
ASSERT(AfxIsValidString(lpszFaceName));

LOGFONT logFont;
memset(&logFont, 0, sizeof(LOGFONT));
logFont.lfCharSet = DEFAULT_CHARSET;
logFont.lfHeight = nPointSize;
lstrcpyn(logFont.lfFaceName, lpszFaceName, _countof(logFont.lfFaceName));

return CreatePointFontIndirect(&logFont, pDC);
}

BOOL CFont::CreatePointFontIndirect(const LOGFONT* lpLogFont, CDC* pDC)
{
ASSERT(AfxIsValidAddress(lpLogFont, sizeof(LOGFONT), FALSE));
HDC hDC;
if (pDC != NULL)
{
ASSERT_VALID(pDC);
ASSERT(pDC->m_hAttribDC != NULL);
hDC = pDC->m_hAttribDC;
}
else
hDC = ::GetDC(NULL);

// convert nPointSize to logical units based on pDC
LOGFONT logFont = *lpLogFont;
POINT pt;
pt.y = ::GetDeviceCaps(hDC, LOGPIXELSY) * logFont.lfHeight;
pt.y /= 720; // 72 points/inch, 10 decipoints/point
pt.x = 0;
::DPtoLP(hDC, &pt, 1);
POINT ptOrg = { 0, 0 };
::DPtoLP(hDC, &ptOrg, 1);
logFont.lfHeight = -abs(pt.y - ptOrg.y);

if (pDC == NULL)
ReleaseDC(NULL, hDC);

return CreateFontIndirect(&logFont);
}
因此你可以转换以上C++代码。或者干脆这样不就完事了：
Font f = new Font(familyName, emSize);

谢谢楼上兄弟？

MFC中CFont::CreatePointFont方法与c#中的Font f = new Font(familyName, emSize)方法是不是等效的啊？

其实C#就是封装了一些底层的方法,让开发人员用得简单,
font就是C#里操作字体的类,
