1.使用SqlDataAdapter
SqlDataAdapter sda = new SqlDataAdapter(**)
DataSet ds = new DataSet();
sda.Fill(ds);
this.dataGridView1.DataSource = ds.Tables[0];
2.使用
SqlDataReader sdr = command.ExecuteReader();
BindingSource BS = new BindingSource();
bs.DataSource = sdr;
this.dataGridView1.DataSource = BS;
暂时就这样吧
