C#操作实现Word全域查找且替换

作者：初九之潜龙勿用

这篇文章主要为大家详细介绍了C#如何操作实现Word全域查找且替换功能,文中的示例代码讲解详细,具有一定的借鉴价值,有需要的小伙伴可以参考下

关于全域查找且替换

C#全域操作 Word 查找且替换主要包括如下四个对象：

序号对象说明
1Word.Appication.Selection窗格对象
2Word.Section.Headers[Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range页眉对象
3Word.Section.Footers[Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range页脚对象
4Word.Shape.TextFrame.TextRange形状对象

我们需要创建 Word.Find 对象，对上述相关区域分别进行查找替换操作。

Word应用样本

我们假设设计简历模板的输出，并查找且替换对应的关键字，如下图：

其中对应项目的关键字如 {xm}、{xb} 等则为查找且替换的对象，{grzp} 关键字处我们要处理图片的插入。

SqlServer数据表部分设计样本

设计 PersonInfo 数据表如下：

CREATE TABLE [dbo].[PersonInfo](
	[id] [uniqueidentifier] ROWGUIDCOL  NOT NULL,
	[sfzh] [varchar](18) NOT NULL,
	[xm] [nvarchar](50) NOT NULL,
	[xb] [nvarchar](1) NULL,
	[grzp] [image] NULL,
 CONSTRAINT [PK_PersonInfo] PRIMARY KEY CLUSTERED 
(
	[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY],
 CONSTRAINT [IX_PersonInfo] UNIQUE NONCLUSTERED 
(
	[sfzh] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
 
ALTER TABLE [dbo].[PersonInfo] ADD  CONSTRAINT [DF_PersonInfo_id]  DEFAULT (newid()) FOR [id]
GO

通过查询 select sfzh,xm,xb,grzp from PersonInfo where id=xxx 得到DataSet，再取 Tables[0]中的数据。 

范例运行环境

操作系统： Windows Server 2019 DataCenter

操作系统上安装 Office Excel 2016

数据库：Microsoft SQL Server 2016

.net版本： .netFramework4.7.1 或以上

开发工具：VS2019  C#

配置Office DCOM

配置方法可参照我的文章《C# 读取Word表格到DataSet》进行处理和配置。

设计实现

组件库引入

实现原理

我们假设查询出表数据，存入对应的变量，其中将二进制字段grzp数据写入到d:\test.jpg生成图片，示例代码如下：

DataTable dt=DataSet.Tables[0];
 
string sfzh = dt.Rows[0]["sfzh"].ToString();
object bt = dt.Rows[0]["grzp"];
byte[] bFile2 = (byte[])bt;
System.IO.File.WriteAllBytes("@d:\test.jpg", bFile2);
 
string xm = dt.Rows[0]["xm"].ToString();
string xb = dt.Rows[0]["xb"].ToString();

然后我们将其存到二维字符串数组 _repls 里，如下代码：

string[,] _repls = new string[4, 2];
_repls[0, 0] = "{sfzh}";
_repls[0, 1] = sfzh;
_repls[1, 0] = "{xm}";
_repls[1, 1] = xm;
_repls[2, 0] = "{xb}";
_repls[2, 1] = xb;
_repls[3, 0] = "RepalceFromImageFilename_{grzp}";
_repls[3, 1] = "@d:\test.jpg";

其中第一元素存储要查找的关键字，第二元素存储要替换的值。注意：替换图片使用了自定义的RepalceFromImageFilename_ 前缀关键字，则表示值为对应的文件路径。数据准备完毕后，我们将通过遍历数组对 Word 进行查找且替换操作。

小结

1、示例代码是冗余的写法，在实际应用中我们需要进行优化。

2、添加图片后，代码默认是使用完毕后，删除图片文件以释放空间，我们自定义了 RepalceFromImageFilenameNoDelete_ 前缀关键字，表示使用完毕后不进行文件删除。

3、示例代码中 Word 表示 using Word=Microsoft.Office.Interop.Word; 的引用。

4、示例代码 WordDoc 表示对 Word.Document 的引用。
