动态解析XML生成EXCEL

在做项目中，可能会遇到这样的需求，根据数据库里的数据生成相应格式Excel表格。生成的Excel表格不是常规的表格，而是存在合并，宽度不一，长短不一这种需求的。

类似于下面的图表：

//要转换的XML文件
creatXML();
string XMLFileName = Path.Combine(Request.PhysicalApplicationPath, "XML\\document.xml");
DataSet dsBook = new DataSet();
dsBook.ReadXml(XMLFileName);
int rows = dsBook.Tables[0].Rows.Count + 1;
int cols = 7;

//将要生成的Excel文件
string ExcelFileName = Path.Combine(Request.PhysicalApplicationPath, "XML\\DMSExcel.xls");
if (File.Exists(ExcelFileName))
{
File.Delete(ExcelFileName);
}
StreamWriter writer = new StreamWriter(ExcelFileName, false);

这个代码只是一种思想，根据XML生成相应的EXCEL关键是设计结构。至于解析数据，学过编程的都会。
