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：
DataSetmDSData=newDataSet();
mDSData.Tables.Add("myTable");
mDSData.Tables["myTable"].Columns.Add("ID");
mDSData.Tables["myTable"].Columns.Add("Name");
mDSData.Tables["myTable"].Columns.Add("PassWord");
for(inti=0;i<10;i++)
{
DataRowdr=mDSData.Tables["myTable"].NewRow();
dr["ID"]=i;
dr["Name"]=i;
dr["PassWord"]=i;
mDSData.Tables["myTable"].Rows.Add(dr);
}
SaveFileDialogdialog1=newSaveFileDialog();
dialog1.AddExtension=true;
dialog1.CheckPathExists=true;
dialog1.Filter="ExcelWorkbooks(*.xls)|*.xls";
dialog1.OverwritePrompt=true;
dialog1.Title="SaveExcelFormattedReport";
if(dialog1.ShowDialog()==DialogResult.OK)
{
intnum2=0;
intnum3=mDSData.Tables[0].Rows.Count+1;
intnum1=mDSData.Tables[0].Columns.Count;
num2=0;
stringtext1=dialog1.FileName;
if(File.Exists(text1))
{
File.Delete(text1);
}
StreamWriterwriter1=newStreamWriter(text1,false);
StreamWriterwriter2=writer1;
writer2.WriteLine("<?xmlversion=\"1.0\"?>");
writer2.WriteLine("<?mso-applicationprogid=\"Excel.Sheet\"?>");
writer2.WriteLine("<Workbookxmlns=\"urn:schemas-microsoft-com:office:spreadsheet\"");
writer2.WriteLine("xmlns:o=\"urn:schemas-microsoft-com:office:office\"");

writer2.WriteLine("<Protection/>");
writer2.WriteLine("</Style>");
writer2.WriteLine("<Styless:ID=\"s21\">");
writer2.WriteLine("<Alignmentss:Vertical=\"Bottom\"ss:WrapText=\"1\"/>");
writer2.WriteLine("</Style>");
writer2.WriteLine("</Styles>");
writer2.WriteLine("<Worksheetss:Name=\"MyReport\">");
writer2.WriteLine(string.Format("<Tabless:ExpandedColumnCount=\"{0}\"ss:ExpandedRowCount=\"{1}\"x:FullColumns=\"1\"",num1.ToString(),num3.ToString()));
writer2.WriteLine("x:FullRows=\"1\">");
foreach(DataRowrow1inmDSData.Tables[0].Rows)
{
writer2.WriteLine("<Row>");
for(num2=0;num2!=num1;num2++)
{
writer2.Write("<Cellss:StyleID=\"s21\"><Datass:Type=\"String\">");
writer2.Write(row1[num2].ToString());
writer2.WriteLine("</Data></Cell>");
}
writer2.WriteLine("</Row>");
}
writer2.WriteLine("</Table>");
writer2.WriteLine("<WorksheetOptionsxmlns=\"urn:schemas-microsoft-com:office:excel\">");
writer2.WriteLine("<Selected/>");
writer2.WriteLine("<Panes>");
writer2.WriteLine("<Pane>");

writer2.WriteLine("</Panes>");
writer2.WriteLine("<ProtectObjects>False</ProtectObjects>");
writer2.WriteLine("<ProtectScenarios>False</ProtectScenarios>");
writer2.WriteLine("</WorksheetOptions>");
writer2.WriteLine("</Worksheet>");
writer2.WriteLine("<Worksheetss:Name=\"Sheet2\">");
writer2.WriteLine("<WorksheetOptionsxmlns=\"urn:schemas-microsoft-com:office:excel\">");
writer2.WriteLine("<ProtectObjects>False</ProtectObjects>");

writer2.WriteLine("</Worksheet>");
writer2.WriteLine("</Workbook>");
writer2=null;
writer1.Close();
MessageBox.Show("ReportCreated","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。
