在Word 文档中创建表单域

---

MS Word 文档表单域通常用于显示、捕获和编辑数据。我们可以在 Microsoft Office Word 中使用模板创建表单并添加内容控件，包括文本框、日期选择器和下拉列表。无需安装 Microsoft Office，开发者就可以使用Spire.Doc在 C# 的 Word 文档中添加字段和创建表单。

Spire.Doc for.NET 最新下载

以下是开发人员如何使用 Spire.Doc 创建 FormField 的详细信息：

• 下载 Spire.Doc for .NET（或 Spire.Office for .NET）并将其安装在您的系统上。
• 通过以下路径在下载的 Bin 文件夹中添加 Spire.Doc.dll 作为参考：“..\Spire.Doc\Bin\NET4.0\ Spire.Doc.dll”。

第一步：创建word文档。

//Create a word document
Document document = new Document();

第 2 步：将新部分添加到文档中，我们将提供有关表单部分的详细信息。表单中主要包含三个字段：文本、下拉列表和复选框。

//Add new section to document
Section section = document.AddSection();

//Add Form to section
private void AddForm(Section section)

//add text input field
TextFormField field
= fieldParagraph.AppendField(fieldId, FieldType.FieldFormTextInput) as TextFormField;

//add dropdown field
DropDownFormField list
= fieldParagraph.AppendField(fieldId, FieldType.FieldFormDropDown) as DropDownFormField;

//add checkbox field
fieldParagraph.AppendField(fieldId, FieldType.FieldFormCheckBox);

第 3 步：将文档保存为 Microsoft Word 格式的文件。

//Save doc file
document.SaveToFile("Sample.doc",FileFormat.Doc);
