C#中datagridview用dataset绑定远程oracle中的数据却不显示，请大家帮帮忙吧

Question

下面是代码，应该没什么问题啊，而且也没报错，就是数据都不显示
private void Form1_Load(object sender, EventArgs e)
{

string connstring = "Data Source=(DESCRIPTION="
+
" (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.1)(PORT = 1521))"
+ "(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orclserv)));"
+"User Id=fdjh_maker;Password=fdjh;";

OracleConnection con = new OracleConnection(connstring);
DataSet myset = new DataSet();
con.Open();
OracleDataAdapter adapter = new OracleDataAdapter("select * from han_table", con);
adapter.Fill(myset);
this.dataGridView1.DataSource = myset.Tables["han_table"];
}

Answer 1

把最后一句改成dataGridView1.DataSource = myset.Tables[0];就行了，你从数据库里han_table查出来的DataTable表名可不是han_table
