namespace 数据导入导出
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void import_Click(object sender, EventArgs e)
{
if (odfImport.ShowDialog()==DialogResult.OK)
{
using (FileStream fileStream = File.OpenRead(odfImport.FileName))
{
using (StreamReader streamReader = new StreamReader(fileStream))
{
string line = null;
while ((line = streamReader.ReadLine()) != null)
{
string[] strs = line.Split('|');
string name = strs[0];
int age = Convert.ToInt32(strs[1]);
using (SqlConnection conn = new SqlConnection(@"Data Source=.\sqlexpress;attachDBFilename=|DataDirectory|\Database1.mdf1;Integrated Security=True;User Instance=True"))
{
conn.Open();
using (SqlCommand cmd = conn.CreateCommand())
{
cmd.CommandText = "Insert into T_users(Name,Age) values(@Name,@Age)";
cmd.Parameters.Add(new SqlParameter("Name", name));
cmd.Parameters.Add(new SqlParameter("Age", age));
cmd.ExecuteNonQuery();

}

}

}
}
}
MessageBox.Show("导入成功！");

}
}
}
}

以上所述代码是数据的导入代码，需要认真研究！
