            Data.IEbeln = "4500000003"; //采购凭证
            Data.IEbelp = "00001";  //项目号
            Data.IWerks = "1710";   //工厂
            Data.EtEkpo = new WebReference.ZtestTEkpo[1];
            var res = z_WS004.ZTestRfcEkpoLhy(Data); //传出的参数
            TextBox1.Text = res.EsEkpo.Ebeln + " " +
                res.EsEkpo.Ebelp  + " " +

               res.EsEkpo.Menge;    //传出的结构里面的值
            WebReference.ZtestTEkpo[] ztestTs = res.EtEkpo; //传出的表
            this.GridView1.AutoGenerateColumns = true;
            this.GridView1.DataSource = ztestTs;
            this.GridView1.DataBind();
        }

        //要加上下面的，否则会报错
        protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {
