Question

我需要从我的don net应用程序生成报告文件。我需要将数据放在表格格式中。通常，您希望我使用Microsoft报表查看器控件。但我使用的是sqlite，并且无法自动生成报告。此外，我的报告基于多个表，而不是基于特定的表。所以我决定使用RichTextFormat或Word .doc。

我需要创建一个看起来像这样的报告

-------------------------------------------------------------------------
|    Column 1     |    Column 2     |    Column 3     |    Column 4     |
-------------------------------------------------------------------------
|                 |                 |                 |                 |
|                 |                 |                 |                 |
|                 |                 |                 |                 |
-------------------------------------------------------------------------

当然，行不是固定的，但可以更小。你能告诉我最好的办法吗？

您可以使用“Office Open XML”并构建您自己的docx编写器，查看此wiki url以获取更多信息。在dotnet中，您将获得此作业的特定命名空间。希望这会对你有所帮助。

您也可以使用互操作库并直接写入Word文档。特别是如果文档结构非常简单。缺点：必须在将生成报告的计算机上安装Word。下面的例子，记得添加程序集：Microsoft.Office.Interop.Word（... \ Office12 \ Microsoft.Office.Interop.Word.dll），Office（... \ Office12 \ Office.dll）。

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Office.Interop.Word;
using Microsoft.Office.Core;
using System.Runtime.InteropServices;
using System.IO;
using System.Diagnostics;

namespace WriteToWordSO
{
    class Program
    {
        static void Main(string[] args)
        {
            _Application app = null;
            Documents docs = null;
            Document doc = null;
            Range range = null;
            Tables tables = null;
            Table table = null;

            object oMissing = System.Reflection.Missing.Value;
            object oFalse = false;
            object oTrue = true;
            object fileName = Path.Combine(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location), "tmp.doc");
            object fileFormat = WdSaveFormat.wdFormatDocument;

            FileInfo fi = new FileInfo(fileName.ToString());
            if (fi.Exists) fi.Delete();

            int rows = 4, cols = 5;

            try
            {
                app = new ApplicationClass();
                app.Visible = false;
                app.DisplayAlerts = WdAlertLevel.wdAlertsNone;
                app.AutomationSecurity = MsoAutomationSecurity.msoAutomationSecurityForceDisable;

                docs = app.Documents;
                doc = docs.Add(ref oMissing, ref oMissing, ref oMissing, ref oMissing);

                range = doc.Range(ref oMissing, ref oMissing);

                tables = doc.Tables;

                object oAutoFitCell = WdDefaultTableBehavior.wdWord9TableBehavior;
                object oAutoFitWindow = WdAutoFitBehavior.wdAutoFitWindow;

                table = tables.Add(range, rows, cols, ref oAutoFitCell, ref oAutoFitWindow);

                Cell c = null;
                Range cellRange = null;

                // header row
                for (int i = 1; i < cols + 1; i++)
                {
                    c = table.Cell(1, i);
                    cellRange = c.Range;
                    cellRange.Text = "Header " + i.ToString();
                    cellRange.Bold = 1;

                    Marshal.ReleaseComObject(cellRange);
                }

                // data rows
                for (int i = 1; i < cols + 1; i++)
                {
                    for (int j = 1; j < rows; j++)
                    {
                        c = table.Cell(j + 1, i);
                        cellRange = c.Range;
                        cellRange.Text = "Cell " + i.ToString() + j.ToString();
                        Marshal.ReleaseComObject(c);
                        Marshal.ReleaseComObject(cellRange);
                    }
                }

                doc.SaveAs(ref fileName, ref fileFormat, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,

                ((_Document)doc).Close(ref oFalse, ref oMissing, ref oMissing);

                ((_Application)app).Quit(ref oFalse, ref oMissing, ref oMissing);

                Process.Start(fileName.ToString());

            finally

                GC.Collect();

                // its very important to release all used object,
                // otherwise some complications may appear
                if (table != null) Marshal.ReleaseComObject(table);
                table = null;

                if (tables != null) Marshal.ReleaseComObject(tables);
