很多的软件项目几乎都包含着对文档的操作,前面已经介绍过两款操作文档的组件,现在介绍一款文档操作的组件NPOI。

NPOI可以生成没有安装在您的服务器上的Microsoft Office套件的Excel报表,并且在后台调用Microsoft Excel ActiveX更有效率;从Office文档中提取文本,以帮助您实现全文索引功能(大多数时候,此功能用于创建搜索引擎); 从Office文档提取图像; 生成包含公式的Excel工作表。

 一.NPOI组件概述:

NPOI是完全免费使用; 涵盖Excel的大多数功能(单元格样式,数据格式,公式等);支持xls,xlsx,docx;设计为面向接口(看看NPOI.SS命名空间);支持不仅导出而且导入; .Net 2.0甚至为xlsx和docx(虽然我们也支持.NET 4.0); 来自世界各地的成功案例;巨大的基本例子;对隔离存储没有依赖。

 以上是NPOI的优点,其他一些优点可以不用太在意,估计很多人对“支持xls,xlsx,docx”这一特点感觉有些惊讶,因为在很多人的印象里面NPOI就是对Excel进行相关的操作,但是在这里突然看到了对docx也可以操作,这一特点可能让很多人感到欣喜,因为NPOI的的确确是一个很不错的组件,用过的人都说好,我也不例外。

NPOI的运行要求:VS2010与.NET 4.0运行时;VS2005或VS2008与.NET 2.0运行时(SP1);vs2003与.NET 1.1;Mono;ASP.NET中的中等信任环境。

二.NPOI核心类和方法解析:

以上是对NPOI的相关背景和使用环境做了一个简单的介绍,接下来我具体的看一下NPOI的一些核心类和方法,由于下载的是DLL文件,还是采用.NET Reflector对DLL文件进行反编译,以此查看源代码。

如果需要具体的了解NPOI可以直接访问:http://npoi.codeplex.com/SourceControl/latest,提供了NPOI的源码和一些demo,由于本溪介绍的重点是NPOI对Excel的操作,所以下面的类和实例主要是对操作Excel的介绍,如果需要对docx的操作,可以具体查看相应的类demo。

1.XSSFWorkbook类CreateSheet():创建表。

public ISheet CreateSheet(string sheetname)
{
  if (sheetname == null)
  {
    throw new ArgumentException("sheetName must not be null");
  }
  if (this.ContainsSheet(sheetname, this.sheets.Count))
  {
    throw new ArgumentException("The workbook already contains a sheet of this name");
  }
  if (sheetname.Length > 0x1f)
  {
    sheetname = sheetname.Substring(0, 0x1f);
  }
  WorkbookUtil.ValidateSheetName(sheetname);
  CT_Sheet sheet = this.AddSheet(sheetname);
  int index = 1;
  foreach (XSSFSheet sheet2 in this.sheets)
  {
    index = (int) Math.Max((long) (sheet2.sheet.sheetId + 1), (long) index);
  }
Label_0099:
  foreach (XSSFSheet sheet3 in this.sheets)
  {
    index = (int) Math.Max((long) (sheet3.sheet.sheetId + 1), (long) index);
  }
  string fileName = XSSFRelation.WORKSHEET.GetFileName(index);
  foreach (POIXMLDocumentPart part in base.GetRelations())
  {
    if ((part.GetPackagePart() != null) && fileName.Equals(part.GetPackagePart().PartName.Name))
    {
      index++;
      goto Label_0099;
    }
  }
  XSSFSheet item = (XSSFSheet) base.CreateRelationship(XSSFRelation.WORKSHEET, XSSFFactory.GetInstance(), index);
  item.sheet = sheet;
  sheet.id = item.GetPackageRelationship().Id;
  sheet.sheetId = (uint) index;
  if (this.sheets.Count == 0)
  {
    item.IsSelected = true;
  }
  this.sheets.Add(item);
  return item;
}

2.XSSFSheet类Write():将文件流写入到excel。
 

 internal virtual void Write(Stream stream)
{
  bool flag = false;
  if (this.worksheet.sizeOfColsArray() == 1)
  {
    CT_Cols colsArray = this.worksheet.GetColsArray(0);
    if (colsArray.sizeOfColArray() == 0)
    {
      flag = true;
      this.worksheet.SetColsArray(null);
    }
    else
    {
      this.SetColWidthAttribute(colsArray);
    }
  }
  if (this.hyperlinks.Count > 0)
  {
    if (this.worksheet.hyperlinks == null)
    {
      this.worksheet.AddNewHyperlinks();
    }
    CT_Hyperlink[] array = new CT_Hyperlink[this.hyperlinks.Count];
    for (int i = 0; i < array.Length; i++)
    {
      XSSFHyperlink hyperlink = this.hyperlinks[i];
      hyperlink.GenerateRelationIfNeeded(base.GetPackagePart());
      array[i] = hyperlink.GetCTHyperlink();
    }
    this.worksheet.hyperlinks.SetHyperlinkArray(array);
  }
  foreach (XSSFRow row in this._rows.Values)
  {
    row.OnDocumentWrite();
  }
  Dictionary<string, string> dictionary = new Dictionary<string, string>();
  dictionary[ST_RelationshipId.NamespaceURI] = "r";
  new WorksheetDocument(this.worksheet).Save(stream);
  if (flag)
  {
    this.worksheet.AddNewCols();
  }
}

3.XSSFSheet类CreateRow():创建行。

 public virtual IRow CreateRow(int rownum)
{
  CT_Row cTRow;
  XSSFRow row2 = this._rows.ContainsKey(rownum) "htmlcode">
 public ISheet GetSheet(string name)
{
  foreach (XSSFSheet sheet in this.sheets)
  {
    if (name.Equals(sheet.SheetName, StringComparison.InvariantCultureIgnoreCase))
    {
      return sheet;
    }
  }
  return null;
}

5.WorkbookFactory类:

 public class PropertySetFactory
 {
  public static PropertySet Create(DirectoryEntry dir, string name);
  public static PropertySet Create(Stream stream);
  public static SummaryInformation CreateSummaryInformation();
  public static DocumentSummaryInformation CreateDocumentSummaryInformation();
 }

6.DocumentSummaryInformation:

 [Serializable]
public class DocumentSummaryInformation : SpecialPropertySet
{
  // Fields
  public const string DEFAULT_STREAM_NAME = "\x0005DocumentSummaryInformation";

  // Methods
  public DocumentSummaryInformation(PropertySet ps);
  private void EnsureSection2();
  public void RemoveByteCount();
  public void RemoveCategory();
  public void RemoveCompany();
  public void RemoveCustomProperties();
  public void RemoveDocparts();
  public void RemoveHeadingPair();
  public void RemoveHiddenCount();
  public void RemoveLineCount();
  public void RemoveLinksDirty();
  public void RemoveManager();
  public void RemoveMMClipCount();
  public void RemoveNoteCount();
  public void RemoveParCount();
  public void RemovePresentationFormat();
  public void RemoveScale();
  public void RemoveSlideCount();

  // Properties
  public int ByteCount { get; set; }
  public string Category { get; set; }
  public string Company { get; set; }
  public CustomProperties CustomProperties { get; set; }
  public byte[] Docparts { get; set; }
  public byte[] HeadingPair { get; set; }
  public int HiddenCount { get; set; }
  public int LineCount { get; set; }
  public bool LinksDirty { get; set; }
  public string Manager { get; set; }
  public int MMClipCount { get; set; }
  public int NoteCount { get; set; }
  public int ParCount { get; set; }
  public string PresentationFormat { get; set; }
  public override PropertyIDMap PropertySetIDMap { get; }
  public bool Scale { get; set; }
  public int SlideCount { get; set; }
}

具体方法:

private void EnsureSection2()
{
  if (this.SectionCount < 2)
  {
    MutableSection section = new MutableSection();
    section.SetFormatID(SectionIDMap.DOCUMENT_SUMMARY_INFORMATION_ID2);
    this.AddSection(section);
  }
}

以上只是对部分的类和方法做了简单的说明,需要了解更多的内容,可以进入官网下载源码,或者使用软件查看DLL文件。

三.NPOI操作实例:

        }
        //将文件流写入到excel
        workbook.Write(fs);
        return count;
      }
      catch (IOException ioex)
