C#获取Word文档页数，并跳转到指定的页面获取页面信息

using MSWord = Microsoft.Office.Interop.Word;

private MSWord.Application wordApp;  //Word应用程序变量
private MSWord.Document wordDoc;     //Word文档变量
private Object Nothing = Missing.Value;
  //初始化
wordApp = new MSWord.ApplicationClass();
wordDoc = wordApp.Documents.Add(ref Nothing, ref Nothing, ref Nothing, ref Nothing);
// 打开Word
object FileName = strPath;
object readOnly = false;
object isVisible = true;
wordDoc = wordApp.Documents.Open(ref FileName, ref Nothing, ref readOnly,
ref Nothing, ref Nothing, ref Nothing, ref Nothing, ref Nothing,
ref Nothing, ref Nothing, ref Nothing, ref isVisible, ref Nothing,
ref Nothing, ref Nothing, ref Nothing);

// 计算Word文档页数
MSWord.WdStatistic stat = MSWord.WdStatistic.wdStatisticPages;
int num = wordDoc.ComputeStatistics(stat, ref  Nothing);

// 跳转到指定书签
object BookMarkName = "BookMark1";
object what = MSWord.WdGoToItem.wdGoToBookmark;
wordDoc.ActiveWindow.Selection.GoTo(ref what, ref Nothing, ref Nothing, ref BookMarkName);
MessageBox.Show( wordDoc.ActiveWindow.Selection.Paragraphs[1].Range.Text.ToString());

//  跳转到指定页

object What = MSWord.WdGoToItem.wdGoToPage;
object Which = MSWord.WdGoToDirection.wdGoToNext;
object Name = "1"; // 页数
wordDoc.ActiveWindow.Selection.GoTo(ref What, ref Which, ref Nothing, ref Name); // 第二个参数可以用Nothing
wordDoc.ActiveWindow.Selection.Paragraphs[1].Range.Text.ToString();

//  以下是跳转到某个页面之后的操作

// 通过PageSetup可以获取某个页面的信息

// 获取页面的分栏
wordDoc.ActiveWindow.Selection.PageSetup.TextColumn;
