Excel读取与创建方法三： MyXLS

Excel读取与创建方法三： MyXLS

在后台调用excel组件，生成Excel，虽然可以对Excel文件进行完全控制，可以生成任何复杂的格式，但是有个很大的缺点，这种方式会产生很多Excel进程，很难完全清除掉，特别是在出错的时候，可能会使整个服务器崩溃。本文为大家介绍一个C#写的开源组件，并简单说下office2003和以上版本支持的XML格式。

一
操作Excel二进制格式

OpenOffice.org发布过的俩个文档Excel
File Format (BIFF8)Specification和Microsoft
CompoundDocument (OLE2) Format Specification对Excel的二进制格式做了一个比较详细的说明，依靠这些信息，我们可以直接操作Office二进制格式文档。

MyXls是一个C#写的开源组件，可以用来生成具有很多表格且包含格式的Excel文件。它提供了一套基于对象的API，非常容易使用。
1，生成一个空的表格

3， 再创建一个复杂点表格

protected void Page_Load(object sender, EventArgs e)

{

org.in2bits.MyXls.XlsDocument doc = new XlsDocument();

doc.FileName = "TestingAgain.xls";

//doc.Workbook.ProtectContents = true;

for (int s = 1; s <= 5; s++)

{

string sheetName = Request.Form["txtSheet" + s].Replace(",", string.Empty);

if (sheetName.Trim() == string.Empty)

continue;

int rowMin, rowCount, colMin, colCount;

try

{

rowMin = int.Parse(Request.Form["txtRowMin" + s]);

rowCount = int.Parse(Request.Form["txtRows" + s]);

colMin = int.Parse(Request.Form["txtColMin" + s]);

colCount = int.Parse(Request.Form["txtCols" + s]);

}

catch

{

continue;

}

if (rowCount > 65535) rowCount = 65535;

if (rowCount < 0) rowCount = 0;

if (rowMin < 1) rowMin = 1;

if (rowMin > 32767) rowMin = 32767;

if (colCount > 255) colCount = 255;

if (colCount < 1) colCount = 1;

if (colMin < 1) colMin = 1;

if (colMin > 100) colMin = 100;

if (sheetName.Length > 35) sheetName = sheetName.Substring(0, 35);

Worksheet sheet = doc.Workbook.Worksheets.Add(sheetName);

//sheet.Protected = true;

Cells cells = sheet.Cells;

for (int row = 0; row <= rowCount; row++)

{

if (row == 0)

{

for (int col = 1; col <= colCount; col++)

{

Cell cell = cells.Add(rowMin + row, colMin + col - 1, "Fld" + col);

cell.Font.Weight = 700;

cell.DiagonalAscending = true;

cell.DiagonalLineColor = Colors.Black;

cell.DiagonalLineStyle = 2;

//cell.Pattern = 18;

//cell.PatternColorIndex = 0;

//cell.PatternBackgroundColor = Colors.Green;

cell.Locked = true;

}

}

else

{

for (int col = 1; col <= colCount; col++)

{

Cell cell = cells.Add(rowMin + row, colMin + col - 1, /*row + col*/1.001);

cell.Locked = false;

}

}

}

}

doc.Send();

Response.Flush();

Response.End();

}

1

XlsDocument xls = new XlsDocument(); //创建一个空的Excel文档

2


3

xls.Send(); //将文档发送到浏览器。

2， 创建一个复杂点表格


XlsDocument xls = new XlsDocument();


xls.FileName = "Wacky.xls";




//添加文件属性


xls.SummaryInformation.Author = "Tim Erickson"; //作者


xls.SummaryInformation.Subject = "A wacky display of Excel file generation";


xls.DocumentSummaryInformation.Company = "in2bits.org";




for (int sheetNumber = 1; sheetNumber <= 5; sheetNumber++)






{


string sheetName = "Sheet " + sheetNumber;


int rowMin = sheetNumber;


int rowCount = sheetNumber + 10;


int colMin = sheetNumber;


int colCount = sheetNumber + 10;


//创建5个表格


Worksheet sheet = xls.Workbook.Worksheets.AddNamed(sheetName);


Cells cells = sheet.Cells;


for (int r = 0; r < rowCount; r++)






{


if (r == 0)






{


for (int c = 0; c < colCount; c++)






{


//在一行内创建colCount个单元格


cells.Add(rowMin + r, colMin + c, "Fld" + (c + 1)).Font.Bold = true;


}


}
