c#/vb.net 添加 word 域-ag凯发旗舰厅

spire.doc组件为用户提供了多种域类型选择，其中涵盖了word自带的各种域类型。这些域类型被定义在枚举spire.doc.fieldtype中，下图为部分域类型及描述：

该文我们详细介绍如何使用spire.doc添加下面三种常见的word 域：fielddate（日期域），fieldif （条件域）及toc（目录域）。

fielddate （日期域）

//新建一个word文档对象
document document = new document();
//添加一个section和paragraph
section section = document.addsection();
paragraph paragraph = section.addparagraph();
//添加文本到paragraph
paragraph.appendtext("今天的日期为: ");
//添加日期域并设置日期格式
field field = paragraph.appendfield("date", fieldtype.fielddata) as field;
field.code = @"date  \@"   "\"yyyy年mm月dd日 \"";
//保存文档
document.savetofile("sample.docx", fileformat.docx2013);

'新建一个word文档对象
dim document as document = new document
'添加一个section和paragraph
dim section as section = document.addsection
dim paragraph as paragraph = section.addparagraph
'添加文本到paragraph
paragraph.appendtext("今天的日期为: ")
'添加日期域并设置日期格式
dim field as field = ctype(paragraph.appendfield("date", fieldtype.fielddata),field)
field.code = ("date  \@"   """yyyytmmdd  """"")
'保存文档
document.savetofile("sample.docx", fileformat.docx2013)

fieldif（条件域）

spire.doc创建条件域的时候，我们会用到两个域，一个是条件域，一个是邮件合并域。格式为这样{if { mergefield count } > "60" "成绩合格" "成绩不合格"}

{
   //新建一个word文档对象并添加section和paragraph
   document document = new document();
   section section = document.addsection();
   paragraph paragraph = section.addparagraph();
   //调用createiffield方法并赋值
   createiffield(document, paragraph);
   string[] fieldname = { "count" };
   string[] fieldvalue = { "100" };
//合并值到条件域
   document.mailmerge.execute(fieldname, fieldvalue);
//更新域
   document.isupdatefields = true;
 
 //保存文档
   document.savetofile("sample.docx", fileformat.docx); 
  }
 static void createiffield(document document, paragraph paragraph)
 {
  //添加条件域并设置条件
iffield iffield = new iffield(document);
iffield.type = fieldtype.fieldif;
    iffield.code = "if ";
    paragraph.items.add(iffield);
    paragraph.appendfield("count",fieldtype.fieldmergefield);
    paragraph.appendtext(" > ");
    paragraph.appendtext("\"60\" ");
    paragraph.appendtext("\"成绩合格\" ");
    paragraph.appendtext("\"成绩不合格\"");
   iparagraphbase end = document.createparagraphitem(paragraphitemtype.fieldmark);
  (end as fieldmark).type = fieldmarktype.fieldend;
   paragraph.items.add(end);
   iffield.end = end as fieldmark;
}

'新建一个word文档对象并添加section和paragraph
dim document as document = new document
dim section as section = document.addsection
dim paragraph as paragraph = section.addparagraph
'调用createiffield方法并赋值
createiffield(document, paragraph)
dim fieldname() as string
dim fieldvalue() as string
'合并值到条件域
document.mailmerge.execute(fieldname, fieldvalue)
'更新域
document.isupdatefields = true
'保存文档
document.savetofile("sample.docx", fileformat.docx)
    
    private shared sub createiffield(byval document as document, byval paragraph as paragraph)
        '添加条件域并设置条件
        dim iffield as iffield = new iffield(document)
        iffield.type = fieldtype.fieldif
        iffield.code = "if "
        paragraph.items.add(iffield)
        paragraph.appendfield("count", fieldtype.fieldmergefield)
        paragraph.appendtext(" > ")
        paragraph.appendtext("""60"" ")
        paragraph.appendtext("\"成绩合格\" ")
        paragraph.appendtext("\"成绩不合格\"")
        dim end as iparagraphbase = document.createparagraphitem(paragraphitemtype.fieldmark)
        ctype(end,fieldmark).type = fieldmarktype.fieldend
        paragraph.items.add(end)
        iffield.end = ctype(end,fieldmark)
    end sub

toc（目录域）

spire.doc提供了appendtoc()方法让用户能够直接添加目录域。

{
  //新建一个word文档对象并添加section和paragraph
document document = new document();
  section section = document.addsection();
  paragraph paragraph = section.addparagraph();
//添加目录域
  paragraph.appendtoc(1, 3);
//添加内容到段落并设置样式
  paragraph para1 = section.addparagraph();
  para1.appendtext("head1");
  para1.applystyle(builtinstyle.heading1);
  paragraph para2 = section.addparagraph();
  para2.appendtext("head2");
  para2.applystyle(builtinstyle.heading2);
  //更新目录域
  document.updatetableofcontents();
//保存文档
  document.savetofile("toc.docx", fileformat.docx);
  }

'新建一个word文档对象并添加section和paragraph
dim document as document = new document
dim section as section = document.addsection
dim paragraph as paragraph = section.addparagraph
'添加目录域
paragraph.appendtoc(1, 3)
'添加内容到段落并设置样式
dim para1 as paragraph = section.addparagraph
para1.appendtext("head1")
para1.applystyle(builtinstyle.heading1)
dim para2 as paragraph = section.addparagraph
para2.appendtext("head2")
para2.applystyle(builtinstyle.heading2)
'更新目录域
document.updatetableofcontents
'保存文档
document.savetofile("toc.docx", fileformat.docx)
