1.创建服务引用
例如：天气预报
2.在代码添加引用空间
1 ??TvProgram.ChinaTVprogramWebService tp = new TvProgram.ChinaTVprogramWebService();2 ????????DataSet ds= ???tp.getAreaDataSet();
3.引用具体方法
1 ?private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) 2 ????????{ 3 ????????????ComboBox cb = (ComboBox)sender; 4 ????????????if(comboBox1.SelectedIndex>0) 5 ????????????{ ?6 ????????????7 ?????????????int num= Convert.ToInt32(cb.SelectedValue.ToString()); 8 ?9 ?????????????TvProgram.ChinaTVprogramWebService tp = new TvProgram.ChinaTVprogramWebService();10 ?????????????DataSet ds = tp.getTVstationDataSet(num);11 ?????????????comboBox2.DataSource = ds.Tables[0];12 ?????????????comboBox2.DisplayMember = "tvStationName";13 ?????????????comboBox2.ValueMember = "tvStationID";14 ???????????15 ????????????}16 ????????}返回的xml用两种处理方法
?//DataRow[] dt = ds.Tables[0].Select(); ?????????//for (int i = 3; i < dt.Length; i++) ??????//{ ??????// ???Text = dt[i]["Area"].ToString(); ??????// ??Value = Convert.ToInt32(dt[i]["areaID"].ToString()); ???????// ???comboBox1.Items.Add(Text); ??????//} ??????comboBox1.DataSource = ds.Tables[0]; ???????comboBox1.DisplayMember = "Area"; ???????comboBox1.ValueMember = "areaID";
Web服务的调用
