我想要Sql Server连接textBox的。有添加，修改，删除等操作的。
最好是有多个表的操作。
嘎嘎，是不是为难你了呢

用DataBind方法,把数据绑定到textBox上

this.sqlInsertCommand2.Parameters["@Id"].Value=textBox1.Text;
this.sqlInsertCommand2.Parameters["@name"].Value=textBox2.Text;
this.sqlInsertCommand2.Parameters["@Sex"].Value=textBox3.Text;
this.sqlInsertCommand2.Parameters["@Age"].Value=textBox4.Text;
this.sqlInsertCommand2.Parameters["@Telephone"].Value=textBox5.Text;
this.sqlInsertCommand2.Parameters["@Code"].Value=textBox6.Text;
this.sqlInsertCommand2.Connection.Open();
this.sqlInsertCommand2.ExecuteNonQuery();
this.sqlInsertCommand2.Connection.Close();
this.sqlConnection1.Open();
this.sqlDataAdapter2.Fill(this.dataSet11);
this.sqlConnection1.Close();
this.dataGrid1.Update();
this.dataGrid1.Refresh();
this.textBox1.Text="";this.textBox2.Text="";
this.textBox3.Text="";this.textBox4.Text="";
this.textBox5.Text="";this.textBox6.Text="";




this.sqlDeleteCommand3.CommandText="delete from 表名 where Id='"+this.textBox12.Text.Trim()+"'or Name='"+this.textBox11.Text.Trim()+"'or Sex='"+this.textBox10.Text.Trim()+"'or Age='"+this.textBox9.Text.Trim()+"'or Telephone='"+this.textBox8.Text.Trim()+"'or Code='"+this.textBox7.Text.Trim()+"'";
this.sqlDeleteCommand3.Connection.Open();
this.sqlDeleteCommand3.ExecuteNonQuery();
this.dataSet11.Clear();
this.sqlDataAdapter1.Fill(this.dataSet11);
this.sqlDeleteCommand3.Connection.Close();
this.textBox12.Text="";this.textBox11.Text="";
this.textBox10.Text="";this.textBox9.Text="";
this.textBox8.Text="";this.textBox7.Text="";
