推荐答案

您应该尝试这样的操作.

You should try something like this.

 string query = @"SELECT * FROM Sales_so
  Inner join Com_customer on COM_Customer.Com_customer_id = Sales_SO.Com_customer_Id";
 Connection con = new Connection();
 SqlDataAdapter dataAdapter = new SqlDataAdapter(query, con);

 SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter);
 DataSet ds = new DataSet();
 dataAdapter.Fill(ds);
 dataGridView1.ReadOnly = true; 
 dataGridView.DataSource = ds.tables[0];
