使用 Word 2007 XML 对象模型从 Word 模板生成 Word 文档
2.50/5 (6投票s)
如何使用 Word 2007 XML 格式从 Word 模板生成 Word 文档。
引言
在许多项目中，开发人员需要以特定格式或从模板生成 Word 文档中的报告。 使用服务器端 Word 实例化来生成这些文档的旧方法会消耗大量服务器资源，不建议使用。 一种替代方法是使用 Word 2007 XML 对象进行 Word 生成。 可以此处找到有关 Word 2007 XML 格式的基本信息。
本文涵盖了通过填充书签及其样式，从服务器上的模板生成合同文档。
Using the Code
此代码需要 Word 2007 和 .NET Framework 3.0 或更高版本才能工作。.NET 3.0 附带一个名为 WindowsBase.dll 的特殊 DLL 和一个名为 System.IO.Packaging 的命名空间，用于在不实例化服务器上的 Word 对象的情况下生成 Word 文档。
