如何用C#对word文档进行页码设置

[小明做IT]

public void InsertPageNumber(string strType, bool bHeader)
{
object oAlignment = Word.WdPageNumberAlignment.wdAlignPageNumberCenter;
object oFirstPage = bHeader;
Word.WdHeaderFooterIndex WdFooterIndex = Word.WdHeaderFooterIndex.wdHeaderFooterPrimary;
switch (strType)
{
case "Center":
oAlignment = Word.WdPageNumberAlignment.wdAlignPageNumberCenter;
break;

case "Right":
oAlignment = Word.WdPageNumberAlignment.wdAlignPageNumberRight;
break;

case "Left":
oAlignment = Word.WdPageNumberAlignment.wdAlignPageNumberLeft;
break;
}
myWordApplication.Selection.Sections.Item(1).Footers.Item(WdFooterIndex).PageNumbers.Add(ref oAlignment, ref oFirstPage);

}

为什么提出出错
提示错误 “Word.Sections”并不包含“Item”的定义

myWordApplication.Selection.Sections.Item(1).Footers.Item(WdFooterIndex).PageNumbers.Add(ref oAlignment, ref oFirstPage); 这句有问题啊！
谁帮我解决啊！谢谢了

myWordApplication.Selection.Sections[1].Footers[WdFooterIndex].PageNumbers.Add(ref oAlignment, ref oFirstPage);
