.net 不能写入数据库的问题？

Question

一个小程序　
点击按钮执行插入一行，程序运行没有错误，但打开数据库发现并没有插入，请问为什么？片断如下：private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                db1DataSet.wordRow newRow = db1DataSet1.word.NewwordRow();                newRow["word"] = "1234";                
                newRow["means"] = "4534";
                newRow["ok"] = false;
                newRow["ord"] = 3;                db1DataSet1.word.Rows.Add(newRow);                               
                wordTableAdapter1.Update(db1DataSet1); 
            }
            catch (Exception e1)
            {
                Console.WriteLine(e1.ToString());
            }
        }谢谢大家！

public static void  InSertDB()
{
SqlConnection con = DB.CreateDBcon();
string sql="插入语句"
con.Open();
SqlCommand cmd=new SqlCommand(sql,con);
try
{
cmd.ExecuteNonQuery();
writeFile(newId);
}
catch
{
Console.Write("插入出错了");
}
finally
{
cmd.Dispose();
con.Close();
} }

Answer 2

                  public static void  InSertDB()//多写了一点
{
SqlConnection con = DB.CreateDBcon();
string sql="插入语句";
con.Open();
SqlCommand cmd=new SqlCommand(sql,con);
try
{
cmd.ExecuteNonQuery();
}
catch
{
Console.Write("插入出错了");
}
finally
{
         cmd.Dispose();
         con.Close();
} }
