我想在datagridview中显示指定的列值.示例:从表 user_account 中我要显示和搜索datagridview

I want to display in datagridview a specified column value. Example: from table user_account I want to display and search by textbox data from column account in datagridview

Here is the code so far:

{
        string connectionString = @"Data Source=" + textBox4.Text + ";" + "Initial Catalog=" + textBox1.Text + ";" + "User ID=" + textBox2.Text + ";" + "Password=" + textBox3.Text;
        string sql = "SELECT * FROM user_account";
        SqlConnection connection = new SqlConnection(connectionString) ;
        SqlDataAdapter dataadapter = new SqlDataAdapter(sql, connection);
        DataSet ds = new DataSet();
        connection.Open();
        dataadapter.Fill(ds, "account");
        connection.Close();
        dataGridView1.DataSource = ds;
        dataGridView1.DataMember = "account";
    }

推荐答案

private void button3_Click(object sender, EventArgs e)
    {
        string connectionString = @"Data Source=" + textBox4.Text + ";" + "Initial Catalog=" + textBox1.Text + ";" + "User ID=" + textBox2.Text + ";" + "Password=" + textBox3.Text;
        string sql = "SELECT account FROM user_account";
        SqlConnection connection = new SqlConnection(connectionString) ;
        SqlDataAdapter dataadapter = new SqlDataAdapter(sql, connection);
        DataSet ds = new DataSet();
        connection.Open();
        dataadapter.Fill(ds, "account");
        connection.Close();
        dataGridView1.DataSource = ds;

    }
