string constr = @"Data Source=192.168.*.*; Database=wsditsupport; User ID=**; Password=**";
public Form7()
{
InitializeComponent();
MySqlConnection cn = new MySqlConnection(constr);
string value = "SELECT passover_info FROM probing_production";
MySqlDataAdapter adp = new MySqlDataAdapter(value, cn);
DataTable dt = new DataTable();
adp.Fill(dt);
comboBox1.DataSource = dt;
comboBox1.DisplayMember = "passover_info";
cn.Close();
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (comboBox1.SelectedIndex == -1)
{
textBox1.Text = string.Empty;
}
else
{
textBox1.Text = comboBox1.SelectedItem.ToString();
}
}
}
我尝试过:
当我尝试运行调试时,这是我进入文本框的结果>>> System.Data.DataRowView
What I have tried:
When I try run debug, This is the result I get into textbox >>> "System.Data.DataRowView"

textBox1.Text = ((DataRowView)comboBox1.SelectedItem)["passover_info"].ToString();
}
