使用C#实现在word中插入页眉页脚的方法

public void InsertFooter(string footer) 
{ 
  if (ActiveWindow.ActivePane.View.Type == WdViewType.wdNormalView || 
    ActiveWindow.ActivePane.View.Type == WdViewType.wdOutlineView) 
  { 
    ActiveWindow.ActivePane.View.Type = WdViewType.wdPrintView; 
  } 
 
  ActiveWindow.View.SeekView = WdSeekView.wdSeekCurrentPageFooter; 
  this.Application.Selection.HeaderFooter.LinkToPrevious = false; 
  this.Application.Selection.HeaderFooter.Range.ParagraphFormat.Alignment = WdParagraphAlignment.wdAlignParagraphCenter; 
  ActiveWindow.ActivePane.Selection.InsertAfter(footer); 
 
  //跳出页眉页脚设置 
  ActiveWindow.View.SeekView = WdSeekView.wdSeekMainDocument; 
 
} 

foreach (Word.Section wordSection in this.Application.ActiveDocument.Sections) 
{ 
    Word.Range footerRange = wordSection.Footers[Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range; 
    footerRange.Font.ColorIndex = Word.WdColorIndex.wdDarkRed; 
    footerRange.Font.Size = 20; 
    footerRange.Text = "页脚 页脚"; 
} 

foreach (Word.Section section in this.Application.ActiveDocument.Sections) 
{ 
    Word.Range headerRange = section.Headers[Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range; 
    headerRange.Fields.Add(headerRange, Word.WdFieldType.wdFieldPage); 
    headerRange.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphRight; 
}
