我有一个多页单词文档，我的目标是自定义页码格式，如'19 -x'，其中x可以是1,2,5等。实际上，单词的页面字段不是我想要的。 所以我的解决方案是绘制一个形状，我可以在每个页面的第一段中通过打开xml插入一个像'19'或甚至'19 -1'的文本：
<w:pict>
<v:shapetype id="_x0000_t202" coordsize="21600,21600" o:spt="202" path="m,l,21600r21600,l21600,xe">
<v:stroke joinstyle="miter" />
<v:path gradientshapeok="t" o:connecttype="rect" />
</v:shapetype>
<v:shape id="_x0000_s2050" type="#_x0000_t202" style="position:absolute;left:0;text-align:left;margin-left:-1in;margin-top:708pt;width:39.75pt;height:12.75pt;z-index:251658240;v-text-anchor:middle" filled="f">
<v:textbox inset="0,0,0,0">
<w:txbxContent>
<w:p w:rsidR="00172BF9" w:rsidRDefault="00172BF9" w:rsidP="00172BF9">
<w:r>
<w:rPr>
<w:rFonts w:hint="eastAsia" />
</w:rPr>
<w:t>19-1</w:t>
</w:r>
</w:p>
</w:txbxContent>
</v:textbox>
</v:shape>
</w:pict>
我想要做的是将值设置为<v:shape/>元素中样式属性的 margin-top 属性。到现在为止，我已经拥有了页脚的位置，只需将其命名为 fieldParaRangeTop ：
HeaderFooter footer = currentDocument.Sections[1].Footers[WdHeaderFooterIndex.wdHeaderFooterPrimary];
Range footerRange = footer.Range;
int left,top,width,height ;// px
currentDocument.ActiveWindow.GetPoint(out left,out top,out width,out height,footerRange);
float fieldParaRangeTop = top * 3 / 4;// pt
现在，我需要获得每个页面中第一段的位置，因此我可以使用 fieldParaRangeTop 来减去它：
Paragraph fistParaEachPage = ...;// first para of each page;
int top;
currentDocument.ActiveWindow.GetPoint(out left,out top,out width,out height,fistParaEachPage.Range);
float fpTop = top * 3 / 4;
margin-top 的值为：
value = fieldParaRangeTop - fpTop;
这是新页码相对于每页第一段显示的地方。
结果是第一页中第一段的位置： fpTop = 104pt，但在第二页： fpTop = 178pt。
我的问题是，第一页中的段落和第二页中的段落都是每个页面中的第一段，为什么方法currentDocument.ActiveWindow.GetPoint(out left,out top,out width,out height,paragraph.Range)可能会输出不同的顶部价值？我怎样才能得到正确的值？
谢谢！

答案 0 :(得分：0)
事实上，每页中第一段的位置可能不同。在为方法（例如段落范围）调用方法Window.ScrollIntoView之后，滚动对象并更改其位置。以下是我的新解决方案：
defaultDistance = fieldParaRangeTop - fpTop;。通常，此值是常量。
paraDistance = defaultDistance - relativeDistance。这是第一段相对于页脚的值，页码形状相对于第一段。
