C#利用XML创建Excel文档的实现方法

一般来说C#在不安装Excel软件的情况下，可以通过XML来创建Excel文档。因此，运行本文所述代码您无需安装Excel程序。本文原例子是使用VB.Net写的，以下的用C#改写的代码，分享给大家，供大家参考。

具体代码如下：

DataSet mDSData = new DataSet();
mDSData.Tables.Add("myTable");
mDSData.Tables["myTable"].Columns.Add("ID");
mDSData.Tables["myTable"].Columns.Add("Name");
mDSData.Tables["myTable"].Columns.Add("PassWord");
for (int i = 0; i < 10; i++)
{
 DataRow dr = mDSData.Tables["myTable"].NewRow();
 dr["ID"] = i;
 dr["Name"] = i;
 dr["PassWord"] = i;
 mDSData.Tables["myTable"].Rows.Add(dr);
}
SaveFileDialog dialog1 = new SaveFileDialog();
dialog1.AddExtension = true;
dialog1.CheckPathExists = true;
dialog1.Filter = "Excel Workbooks (*.xls) | *.xls";
dialog1.OverwritePrompt = true;
dialog1.Title = "Save Excel Formatted Report";
if (dialog1.ShowDialog() == DialogResult.OK)
{
 int num2 = 0;
 int num3 = mDSData.Tables[0].Rows.Count + 1;
 int num1 = mDSData.Tables[0].Columns.Count;
 num2 = 0;
 string text1 = dialog1.FileName;
 if (File.Exists(text1))
 {
   File.Delete(text1);
 }
 StreamWriter writer1 = new StreamWriter(text1, false);
 StreamWriter writer2 = writer1;
 writer2.WriteLine("<?xml version=\"1.0\"?>");
 writer2.WriteLine("<?mso-application progid=\"Excel.Sheet\"?>");
 writer2.WriteLine("<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\"");
 writer2.WriteLine(" xmlns:o=\"urn:schemas-microsoft-com:office:office\"");
 writer2.WriteLine(" xmlns:x=\"urn:schemas-microsoft-com:office:excel\"");
 writer2.WriteLine(" xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\"");
 writer2.WriteLine(" xmlns:html=\"http://www.w3.org/TR/REC-html40\">");
 writer2.WriteLine(" <DocumentProperties xmlns=\"urn:schemas-microsoft-com:office:office\">");
 writer2.WriteLine(" <Author>Automated Report Generator Example</Author>");
 writer2.WriteLine(string.Format(" <Created>{0}T{1}Z</Created>", DateTime.Now.ToString("yyyy-mm-dd"), DateTime.Now.ToString("HH:MM:SS")));
 writer2.WriteLine(" <Company>Your Company Here</Company>");
 writer2.WriteLine(" <Version>11.6408</Version>");
 writer2.WriteLine(" </DocumentProperties>");
 writer2.WriteLine(" <ExcelWorkbook xmlns=\"urn:schemas-microsoft-com:office:excel\">");
 writer2.WriteLine(" <WindowHeight>8955</WindowHeight>");
 writer2.WriteLine(" <WindowWidth>11355</WindowWidth>");
 writer2.WriteLine(" <WindowTopX>480</WindowTopX>");
 writer2.WriteLine(" <WindowTopY>15</WindowTopY>");
 writer2.WriteLine(" <ProtectStructure>False</ProtectStructure>");
 writer2.WriteLine(" <ProtectWindows>False</ProtectWindows>");
 writer2.WriteLine(" </ExcelWorkbook>");
 writer2.WriteLine(" <Styles>");
 writer2.WriteLine(" <Style ss:ID=\"Default\" ss:Name=\"Normal\">");
 writer2.WriteLine("  <Alignment ss:Vertical=\"Bottom\"/>");
 writer2.WriteLine("  <Borders/>");
 writer2.WriteLine("  <Font/>");
 writer2.WriteLine("  <Interior/>");
 writer2.WriteLine("  <Protection/>");
 writer2.WriteLine(" </Style>");
 writer2.WriteLine(" <Style ss:ID=\"s21\">");
 writer2.WriteLine("  <Alignment ss:Vertical=\"Bottom\" ss:WrapText=\"1\"/>");
 writer2.WriteLine(" </Style>");
 writer2.WriteLine(" </Styles>");
 writer2.WriteLine(" <Worksheet ss:Name=\"MyReport\">");
 writer2.WriteLine(string.Format(" <Table ss:ExpandedColumnCount=\"{0}\" ss:ExpandedRowCount=\"{1}\" x:FullColumns=\"1\"", num1.ToString(), num3.ToString()));
 writer2.WriteLine("  x:FullRows=\"1\">");
 foreach (DataRow row1 in mDSData.Tables[0].Rows)
 {
   writer2.WriteLine("<Row>");
   for (num2 = 0; num2 != num1; num2++)
   {
     writer2.Write("<Cell ss:StyleID=\"s21\"><Data ss:Type=\"String\">");
     writer2.Write(row1[num2].ToString());
     writer2.WriteLine("</Data></Cell>");
   }
   writer2.WriteLine("</Row>");
 }
 writer2.WriteLine(" </Table>");
 writer2.WriteLine(" <WorksheetOptions xmlns=\"urn:schemas-microsoft-com:office:excel\">");
 writer2.WriteLine("  <Selected/>");
 writer2.WriteLine("  <Panes>");
 writer2.WriteLine("  <Pane>");
 writer2.WriteLine("   <Number>3</Number>");
 writer2.WriteLine("   <ActiveRow>1</ActiveRow>");
 writer2.WriteLine("  </Pane>");
 writer2.WriteLine("  </Panes>");
 writer2.WriteLine("  <ProtectObjects>False</ProtectObjects>");
 writer2.WriteLine("  <ProtectScenarios>False</ProtectScenarios>");
 writer2.WriteLine(" </WorksheetOptions>");
 writer2.WriteLine(" </Worksheet>");
 writer2.WriteLine(" <Worksheet ss:Name=\"Sheet2\">");
 writer2.WriteLine(" <WorksheetOptions xmlns=\"urn:schemas-microsoft-com:office:excel\">");
 writer2.WriteLine("  <ProtectObjects>False</ProtectObjects>");
 writer2.WriteLine("  <ProtectScenarios>False</ProtectScenarios>");
 writer2.WriteLine(" </WorksheetOptions>");
 writer2.WriteLine(" </Worksheet>");
 writer2.WriteLine(" <Worksheet ss:Name=\"Sheet3\">");
 writer2.WriteLine(" <WorksheetOptions xmlns=\"urn:schemas-microsoft-com:office:excel\">");
 writer2.WriteLine("  <ProtectObjects>False</ProtectObjects>");
 writer2.WriteLine("  <ProtectScenarios>False</ProtectScenarios>");
 writer2.WriteLine(" </WorksheetOptions>");
 writer2.WriteLine(" </Worksheet>");
 writer2.WriteLine("</Workbook>");
 writer2 = null;
 writer1.Close();
 MessageBox.Show("Report Created", "Success", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
}

这只是主要的代码，使用前需要此入using相应的命名空间，如果不知道需要哪个命名空间，可在编译时根据提示逐个添加。
