1、修改数据
DataRow dr = hRDataSet.Tables[\"emp\"].Rows.Find(textBox3.Text);
//DataRow dr = hRDataSet.Tables[\"emp\"].Select(\"id=\"+textBox3.Text)[0];
dr.BeginEdit();
dr[\"name\"] = textBox1.Text;
dr.EndEdit();
SqlCommandBuilder cmd=new SqlCommandBuilder(empTableAdapter);
empTableAdapter.Update(hRDataSet);
this.empTableAdapter.Fill(this.hRDataSet.emp);
2、插入数据
DataSet ds = new DataSet();
using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings[\"db\"].ConnectionString))
{
String sql = \"select id,name,age from emp\";
SqlDataAdapter adp = new SqlDataAdapter(sql, conn);
adp.Fill(ds);
DataRow dr=ds.Tables[0].NewRow();
dr[\"name\"]=txtName.Text;
dr[\"age\"] = Convert.ToInt32(txtAge.Text);
SqlCommandBuilder cmd=new SqlCommandBuilder(adp);
ds.Tables[0].Rows.Add(dr);
adp.Update(ds);
}
3、删除数据
DataRow dr = hRDataSet.Tables[\"emp\"].Rows.Find(textBox3.Text);
//DataRow dr = hRDataSet.Tables[\"emp\"].Select(\"id=\"+textBox3.Text)[0];
dr.Delete();
SqlCommandBuilder cmd=new SqlCommandBuilder(empTableAdapter);
empTableAdapter.Update(hRDataSet);
this.empTableAdapter.Fill(this.hRDataSet.emp);
