例子

展示如何使用字段集合。

public void FieldCollection()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    builder.InsertField(" DATE \\@ \"dddd, d MMMM yyyy\" ");
    builder.InsertField(" TIME ");
    builder.InsertField(" REVNUM ");
    builder.InsertField(" AUTHOR  \"John Doe\" ");
    builder.InsertField(" SUBJECT \"My Subject\" ");
    builder.InsertField(" QUOTE \"Hello world!\" ");
    doc.UpdateFields();

    FieldCollection fields = doc.Range.Fields;

    Assert.AreEqual(6, fields.Count);

    // 遍历字段集合，并打印内容和类型
    // 使用自定义访问者实现的每个字段。
    FieldVisitor fieldVisitor = new FieldVisitor();

    using (IEnumerator<Field> fieldEnumerator = fields.GetEnumerator())
    {
        while (fieldEnumerator.MoveNext())
        {
            if (fieldEnumerator.Current != null)
            {
                fieldEnumerator.Current.Start.Accept(fieldVisitor);
                fieldEnumerator.Current.Separator?.Accept(fieldVisitor);
                fieldEnumerator.Current.End.Accept(fieldVisitor);
            }
            else
            {
                Console.WriteLine("There are no fields in the document.");
            }
        }
    }

    Console.WriteLine(fieldVisitor.GetText());
}

    public FieldVisitor()

        mBuilder = new StringBuilder();

        mBuilder.AppendLine("\tDisplayed as: " + fieldStart.GetField().Result);

        return VisitorAction.Continue;
    }

    /// <summary>

    /// </summary>
    public override VisitorAction VisitFieldSeparator(FieldSeparator fieldSeparator)
    {
        mBuilder.AppendLine("\tFound separator: " + fieldSeparator.GetText());

        return VisitorAction.Continue;
    }

    /// <summary>
    /// 在文档中遇到 FieldEnd 节点时调用。
    /// </summary>
    public override VisitorAction VisitFieldEnd(FieldEnd fieldEnd)
    {
        mBuilder.AppendLine("End of field: " + fieldEnd.FieldType);

        return VisitorAction.Continue;
    }

    private readonly StringBuilder mBuilder;
