例子

演示如何使用各种字段类型链接到本地文件系统中的其他文档并显示其内容。

public void FieldLinkedObjectsAsText(InsertLinkedObjectAs insertLinkedObjectAs)
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    // 下面是三种类型的字段，我们可以使用它们以文本形式显示链接文档中的内容。
    // 1 - 链接字段：
    builder.Writeln("FieldLink:\n");

    // 2 - DDE 字段：
