打印 HasMorePages 不起作用 c#

好吧，所以我一直在四处寻找（在 SO 和 Google 上），看看一个问题是否可以解决我的错误，但显然不能，所以这里是：

我正在尝试打印有时会超过一页的内容，并且我正在检查要打印的页数。检查完所有这些逻辑后，我使用HasMorePages属性来设置是否有其他页面。这是我的代码：

int currentpage = 0;
int pagesleft = 0;
private void doc_PrintPage(object sender, PrintPageEventArgs ev)
{
    ev.Graphics.Clear(Color.White);
    int numofpages = (int)Math.Ceiling((double)(numofwords / 29.0));
    numofpages = (int)Math.Ceiling((double)(numofwords / 29.0));
    currentpage = currentpage + 1;
    if(currentpage == 1)
    {
        pagesleft = numofpages;
    }
    if (numofwordsleft >= 29)
    {
        currentwords = 29;
    }
    else
    {
        currentwords = numofwordsleft;
    }
    Font f19 = new Font("Arial", (float)19);
    Font f9 = new Font("Arial", (float)9);            

    ev.Graphics.DrawString("Pages: "+numofpages.ToString()+"         Words: "+numofwords.ToString()+"     "+currentwords.ToString(), f19, Brushes.Red, 200, 300);
    ev.Graphics.DrawString("Words Left: "+numofwordsleft, f19, Brushes.Green, 200, 500);

    ev.Graphics.DrawString("Pages: "+numofpages.ToString()+"       Current Page: "+currentpage.ToString(), f19, Brushes.Blue, 200, 700);

    numofwordsleft = numofwordsleft - currentwords;
    pagesleft = pagesleft - 1;

    //currentpage++;
    //if (currentpage != numofpages && currentpage < numofpages && pagesleft > 0 && pagesleft != 0)
    if(currentpage < numofpages)
    {
        ev.HasMorePages = true;
    }
    else 
    {
        ev.HasMorePages = false;
    }
}

现在一切都正常工作，但是当我尝试打印多于一页时，它会打印 2 页。我做了一些调试并发现了这一点：

So HasMorePages等于false所以它应该只打印一页。我按下继续调试，它再次到达最后的断点。由于我在开始时清除了页面，所以我只看到了第二页（在printpreview）但是printpreview说只有 1 页，唯一显示的页面是第二页。

这里是printpreview:

对于蓝色文本，我正在这样做：

ev.Graphics.DrawString("Pages: "+numofpages.ToString()+"    Current Page: "+currenpage.ToString(), ...);

打印预览清楚地表明它在第 1 页。

很抱歉这篇文章很长，但我需要帮助。如果您可以帮助我/指出解决此问题的正确方向，请在此处发帖。

Thanks!

编辑：所以当我尝试打印 2 页时，使用：

int numofpages = Math.Ceiling(39.0 / 29.0);

它打印 3 页，但全部打印在同一页上，如图所示PrintPreview除非那不能正常工作。

try this

    int currentpage = 0;
    int pagesleft = 0;
    int numofwordsleft = 0;
    int currentwords = 0;//For testing
    int numofwords = 120; // For testing
    private void doc_PrintPage(object sender, PrintPageEventArgs ev)
    {
        ev.Graphics.Clear(Color.White);
        int numofpages = (int)Math.Ceiling((double)(numofwords / 29.0));
        numofpages = (int)Math.Ceiling((double)(numofwords / 29.0));
        currentpage = currentpage + 1;
        if (currentpage == 1)
        {
            pagesleft = numofpages;
        }
        if (numofwordsleft >= 29)
        {
            currentwords = 29;
        }
        else
        {
            currentwords = numofwordsleft;
        }
        Font f19 = new Font("Arial", (float)19);
        Font f9 = new Font("Arial", (float)9);

        ev.Graphics.DrawString("Pages: " + numofpages.ToString() + "         Words: " + numofwords.ToString() + "     " + currentwords.ToString(), f19, Brushes.Red, 200, 300);
        ev.Graphics.DrawString("Words Left: " + numofwordsleft, f19, Brushes.Green, 200, 500);

        ev.Graphics.DrawString("Pages: " + numofpages.ToString() + "       Current Page: " + currentpage.ToString(), f19, Brushes.Blue, 200, 700);

        numofwordsleft = numofwordsleft - currentwords;
        pagesleft = pagesleft - 1;

        //currentpage++;
        //if (currentpage != numofpages && currentpage < numofpages && pagesleft > 0 && pagesleft != 0)
        if (currentpage < numofpages)
        {
            ev.HasMorePages = true;
        }
        else
        {
            ev.HasMorePages = false;
        }
    }

hope this helps. This is the preview i am getting after changing number of words.
