原例子使用VB.Net写的，以下的用C#改写的代码

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);

}

SaveFileDialog dialog1 = new SaveFileDialog();

dialog1.AddExtension = true;

dialog1.CheckPathExists = true;

int num3 = mDSData.Tables[0].Rows.Count + 1;
