1、创建服务引用
例如：天气预报
2、在代码添加引用空间
TvProgram.ChinaTVprogramWebService tp=new TvProgram.ChinaTVprogramWebService(); DataSet ds=tp.getAreaDataSet();
3、引用具体方法
private void comBox1_SelectedIndexChanged(object sender,EventArgs e)
{
ComboBox cb=(ComboBox)sender;
if(ComboBox1.SelectedIndex>0)
{
int num=Convert.ToInt32(cb.SelectedValue.ToString());
TvProgram.ChinaTVprogramWebService tp=new TvProgram.ChinaTVprogramWebService();
DataSet ds=tp.getTVstationDataSet(num);
comboBox2.DataSource=ds.Tables[0];
comboBox2.DisplayMember="tvStationName";
comboBox2.ValueMember="tvStationID";
}
}
返回的XML用两种处理方法
comboBox1.DataSource=ds.Tables[0];
comboBox1.DisplayMember="Area";
comboBox1.ValueMember="areaID";
