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);

}
