C#中WinFrom的下拉框怎么绑定数据库的值

DBHelper类中应该有个返回DataSet的函数，利用该函数返回所有的stuNO值，然后设置

combox.DataSource=返回的DataSet.Tables［0］

combox.DisplayMember="stuNO"

private void Form1_Load(object sender, EventArgs e)

{

String ConnectionString = "Server=.\\mysqlserverDataBase=demouid=sapwd=songhai111"

SqlConnection Connection = new SqlConnection(ConnectionString)//声明数据库链接

string SqlString = "select name from test order by id desc"//查询语句

DataSet dataset = new DataSet()//声明数据集

Connection.Open()//打开数据库

SqlDataAdapter adapter = new SqlDataAdapter(SqlString, Connection)

adapter.Fill(dataset)//读取数据放入数据集

Connection.Close()//关闭数据库

DataTable dt = dataset.Tables[0]//从数据集中取出表

comboBox1.DataSource = dt//下拉列表绑定查询的10条的数据表

comboBox1.DisplayMember = "name"//设置下拉显示的是month行的值

comboBox1.SelectedIndexChanged += new EventHandler(comboBox1_SelectedIndexChanged)

}

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)

{

textBox1.Text = (comboBox1.SelectedValue).ToString()

string txt = this.comboBox1.Text

this.textBox1.Text = txt

}

}

其它功能你自己看着弄就行了
