本例使用XML来创建Excel文档，但在运行时不需要安装Excel程序。
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);
