为什么在WORD里只是显示了第一条记录，后两条没有显示啊

SaveFileDialog sd=new SaveFileDialog();
sd.Filter="txt(*.txt)|*.txt|allfill(*.*)|*.*";
sd.RestoreDirectory=true;
if(sd.ShowDialog()==DialogResult.OK)
{
string flname=sd.FileName;
StreamWriter sw=new StreamWriter(flname);
sw.Write(this.textBox1.Text);
sw.Flush();
sw.Close();
}
