C#导出word [无规则表结构+模板遇到的坑]

1）当然可以考虑使用aspose.word。使用书签替换的方案替换模板中对应的书签值。

2）但是我使用了Interop.Word，下面记录使用类及要注意的地方

3）使用类

Report.cs 来自于网上 修改了在添加表格时焦点移动到最后并新建一页

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Office.Interop.Word;

namespace Song_Public //这边需要换成自己的命名空间名

    public class Report

                bool b = process.MainWindowTitle == "";
                if (process.MainWindowTitle == "")
                {
                    process.Kill();
                }
            }
        }

    }
}

　　4）使用方式

1）按书签导入值 书签设置见下方

            Report report = new Report();
            var path = System.Web.HttpContext.Current.Server.MapPath("/files/word/2.doc");
            var savapath = System.Web.HttpContext.Current.Server.MapPath("/files/word/" + RandomStr.GetSerialNumber(4) + ".doc");
            report.CreateNewDocument(path); //模板路径
            report.InsertValue("name", "世界杯");//在书签“name”处插入值

　　  2）导入表格

Table table2 = report.InsertTable("table2", 4, 4, 0); //在书签“table2”处插入2行3列行宽

　　  3）导入表格数据

report.InsertCell(table2, 1, 1, "项目名称");//表名,行号,列号,值

　　 4）合并单元格

report.MergeCell(table2, 1, 2, 1, 4); //表名,开始行号,开始列号,结束行号,结束列号

　　5）设置字体大小

report.SetFont_Table(table2, "宋体", 11);//宋体14磅

　　6）文档保存

 report.SaveDocument(savapath);

　　7）类中可修改的叮当

  table.Rows.Height = 40; //添加行时可 修改当前行的高度AddRow方法

 //InsertTable方法修改回按书签的位置来添加表格 此方法不适用多个表格的导出

 public Table InsertTable(string bookmark, int rows, int columns, float width)
        {
            object miss = System.Reflection.Missing.Value;
            object oStart = bookmark;
            Range range = wordDoc.Bookmarks.get_Item(ref oStart).Range;//表格插入位置
            Table newTable = wordDoc.Tables.Add(range, rows, columns, ref miss, ref miss);
            //设置表的格式
            newTable.Borders.Enable = 1; //允许有边框，默认没有边框(为0时报错，1为实线边框，2、3为虚线边框，以后的数字没试过)
            newTable.Borders.OutsideLineWidth = WdLineWidth.wdLineWidth050pt;//边框宽度
            if (width != 0)
            {
                newTable.PreferredWidth = width;//表格宽度
            }
            newTable.AllowPageBreaks = false;
            return newTable;
        }

　　

wordApp.Selection.EndKey(WdUnits.wdStory);//焦点放到文档最后

5）注意点

1）表格导出时会嵌套表

原因 ：表格导入完成后 焦点的位置默认会在表格里 在次插入会导致在表格内嵌套

解决：把焦点放到文档末尾 wordApp.Selection.EndKey(WdUnits.wdStory);

2）合并时会报所要求的的成员不存在

原因：这个错误的原因就是没有找到单元格，会有几种情况1）没有代码中定义的书签，2）表格前一项合并完 多列合成一列 后面再用之前的列值来合并。肯定找不到

解决：先输出对应的列与值，最后在处理合并。每次合并都记录，当前行的合并列数 如下

                    //处理合并
                    var pans = 0;//合并数
                    foreach (var o in lo)   //lo为一个list<other>
                    {
                        report.MergeCell(table2, o.row, o.col1-pans, o.row, o.col2- pans);
                        pans++;
                    }

　　3）书签的插入

word->插入->书签->输入书签名称->添加

4）检索 COM 类工厂中 CLSID 为 {000209FF-0000-0000-C000-000000000046} 的组件失败，原因是出现以下错误: 80070005 拒绝访问

原因：没有权限读取word.dll

5）ApplicationClass() 不被识别
