C#導出word [無規則表結構+模板遇到的坑]

1）當然可以考慮使用aspose.word。使用書簽替換的方案替換模板中對應的書簽值。

2）但是我使用了Interop.Word，下面記錄使用類及要注意的地方

3）使用類

                }
            }
        }

    }
}

　　4）使用方式

          1）按書簽導入值 書簽設置見下方

            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); //模板路徑
            report.InsertValue("name", "世界杯");//在書簽“name”處插入值

　　  2）導入表格 

Table table2 = report.InsertTable("table2", 4, 4, 0); //在書簽“table2”處插入2行3列行寬

　　  3）導入表格數據

report.InsertCell(table2, 1, 1, "項目名稱");//表名,行號,列號,值

　　 4）合並單元格

report.MergeCell(table2, 1, 2, 1, 4); //表名,開始行號,開始列號,結束行號,結束列號 

　　5）設置字體大小

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

　　6）文檔保存

 report.SaveDocument(savapath);

　　7）類中可修改的叮當

  table.Rows.Height = 40; //添加行時可 修改當前行的高度AddRow方法

 //InsertTable方法修改回按書簽的位置來添加表格 此方法不適用多個表格的導出

 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);
            //設置表的格式
            newTable.Borders.Enable = 1; //允許有邊框，默認沒有邊框(為0時報錯，1為實線邊框，2、3為虛線邊框，以后的數字沒試過)
            newTable.Borders.OutsideLineWidth = WdLineWidth.wdLineWidth050pt;//邊框寬度
            if (width != 0)
            {
                newTable.PreferredWidth = width;//表格寬度
            }
            newTable.AllowPageBreaks = false;
            return newTable;
        }

　　

wordApp.Selection.EndKey(WdUnits.wdStory);//焦點放到文檔最后

5）注意點 

     1）表格導出時會嵌套表 

                原因 ：表格導入完成后 焦點的位置默認會在表格里 在次插入會導致在表格內嵌套  

                解決：把焦點放到文檔末尾 wordApp.Selection.EndKey(WdUnits.wdStory);

    2）合並時會報所要求的的成員不存在

                原因：這個錯誤的原因就是沒有找到單元格，會有幾種情況1）沒有代碼中定義的書簽，2）表格前一項合並完 多列合成一列 后面再用之前的列值來合並。肯定找不到 

                解決：先輸出對應的列與值，最后在處理合並。每次合並都記錄，當前行的合並列數 如下

                    //處理合並
                    var pans = 0;//合並數
                    foreach (var o in lo)   //lo為一個list<other>    
                    {
                        report.MergeCell(table2, o.row, o.col1-pans, o.row, o.col2- pans);
                        pans++;
                    }

　　3）書簽的插入

word->插入->書簽->輸入書簽名稱->添加  

4）檢索 COM 類工廠中 CLSID 為 {000209FF-0000-0000-C000-000000000046} 的組件失敗，原因是出現以下錯誤: 80070005 拒絕訪問

  原因：沒有權限讀取word.dll

 5）ApplicationClass() 不被識別
