3、ExcelBuilder
Code
using System;using System.Collections.Specialized;using System.Text;using System.Text.RegularExpressions;using System.Xml;using System.Xml.Xsl;using System.Xml.XPath;using System.Data;using System.IO;public class ExcelBuilder{ public ExcelBuilder() { } private void GetXSLFile(DataSet ds, string XslPath, params string[] Titles) { string strColumn = ""; string strRow = ""; string dsName = ds.DataSetName; string tableName = ds.Tables[0].TableName; string header = dsName + "/" + tableName; foreach (string title in Titles) { strColumn += "<th>" + title + "</th>" + "\r\n"; strRow += "<td>" + "<xsl:value-of select=" + "\"" + title + "\"" + "/>" + "</td>" + "\r\n"; } string str = @"<xsl:stylesheet version=""1.0"" xmlns:xsl=""http://www.w3.org/1999/XSL/Transform""> <xsl:template match=""/""> <html xmlns:o=""urn:schemas-microsoft-com:office:office"" xmlns:x=""urn:schemas-microsoft-com:office:excel"" xmlns=""http://www.w3.org/TR/REC-html40""> <head> <meta http-equiv=""Content-Type"" content=""text/html;charset=utf-8"" /> <style> .xl24{mso-style-parent:style0;mso-number-format:""\@"";text-align:right;} </style> <xml> <x:ExcelWorkbook> <x:ExcelWorksheets> <x:ExcelWorksheet> <x:Name>Sheet1</x:Name> <x:WorksheetOptions> <x:ProtectContents>False</x:ProtectContents> <x:ProtectObjects>False</x:ProtectObjects> <x:ProtectScenarios>False</x:ProtectScenarios> </x:WorksheetOptions> </x:ExcelWorksheet> </x:ExcelWorksheets> </x:ExcelWorkbook> </xml> </head> <body> "; str += "\r\n" + @"<table border=""1"" cellpadding=""0"" cellspacing=""0""> <tr>" + "\r\n"; str += strColumn; str += @" </tr> <xsl:for-each select=""" + header + @"""> <tr>"; str += "\r\n" + strRow; str += @"</tr> </xsl:for-each> </table> </body> </html> </xsl:template> </xsl:stylesheet> "; if (File.Exists(XslPath)) { File.Delete(XslPath); } FileStream fs = File.Create(XslPath); StreamWriter sw = new StreamWriter(fs); sw.Write(str); sw.Close(); fs.Close(); } private void GetXmlFile(DataSet ds, string XmlFilePath) { if (File.Exists(XmlFilePath)) { File.Delete(XmlFilePath); } FileStream fs = File.Create(XmlFilePath); StreamWriter writer = new StreamWriter(fs); writer.Write(ds.GetXml()); writer.Close(); fs.Close(); } public bool BuildExcel(DataSet ds, string tempPath, string xslPath) { bool flag = false; if (File.Exists(tempPath)) { File.Delete(tempPath); } string _path = tempPath.Substring(0, tempPath.Length - 4); string _fileXml = _path + ".xml"; string _fileXsl = _path + ".xsl"; string _fileXls = _path + ".xls"; try { GetXmlFile(ds, _fileXml); XmlDocument doc = new XmlDocument(); doc.Load(_fileXml); XslTransform xslt = new XslTransform(); xslt.Load(xslPath); XmlElement root = doc.DocumentElement; XPathNavigator nav = root.CreateNavigator(); XmlTextWriter writer = new XmlTextWriter(_fileXls, null); xslt.Transform(nav, null, writer, null); writer.Close(); File.Delete(_fileXml); flag = true; } catch (Exception ex) { string msg = ex.Message; throw; } return flag; } public bool BuildExcelWithSheets(DataSet ds, string tempPath, string xslPath) { bool flag = false; if (File.Exists(tempPath)) { File.Delete(tempPath); } string _path = tempPath.Substring(0, tempPath.Length - 4); string _fileXml = _path + ".xml"; string _fileXsl = _path + ".xsl"; string _fileXls = _path + ".xls"; string _fileXsd = _path + ".xsd"; try { GetXmlFile(ds, _fileXml); XmlDocument doc = new XmlDocument(); doc.Load(_fileXml); XslTransform xslt = new XslTransform(); xslt.Load(xslPath); XmlElement root = doc.DocumentElement; XPathNavigator nav = root.CreateNavigator(); XmlTextWriter writer = new XmlTextWriter(_fileXsd, null); xslt.Transform(nav, null, writer, null); writer.Close(); File.Delete(_fileXml); StreamReader rd = new StreamReader(_fileXsd, Encoding.UTF8); string ss = rd.ReadToEnd(); ss = ss.Replace("<", "<"); ss = ss.Replace(">", ">"); rd.Close(); StreamWriter sw = new StreamWriter(_fileXls); sw.Write(ss); File.Delete(_fileXsd); sw.Close(); flag = true; } catch (Exception ex) { string msg = ex.Message; throw; } return flag; }}
