OleDbConnection conn=new OleDbConnection(@"provider=microsoft.jet.oledb.4.0;data source=D:\vb3\win32api\WinApi.mdb");
conn.Open();
OleDbDataAdapter adapter=new OleDbDataAdapter("select name from funclass",conn);
DataSet dataset=new DataSet();
adapter.Fill(dataset,"name");
listBox1.DataSource =dataset.Tables[0];
listBox1.DisplayMember=dataset.Tables[0].Columns[0].ToString();
listBox1.ValueMember=dataset.Tables[0].Columns[0].ToString();
conn.Open();
OleDbDataAdapter adapter=new OleDbDataAdapter("select name from funclass",conn);
DataSet dataset=new DataSet();
adapter.Fill(dataset,"name");
listBox1.DataSource =dataset.Tables[0];
listBox1.DisplayMember=dataset.Tables[0].Columns[0].ToString();
listBox1.ValueMember=dataset.Tables[0].Columns[0].ToString();
listBox1.DisplayMember = "device_name";
listBox1.ValueMember= "device_name";
或者
listBox1.DataSource =dataset;
listBox1.DisplayMember = "devices.device_name";
listBox1.ValueMember= "devices.device_name";
当然楼主可以使DisplayMember 和ValueMember指向不同的子段。
