Webservice传递的数据只能是序列化的数据,典型的就是xml数据。
/// <summary>
/// 通过用户名和密码 返回下行数据
/// </summary>
/// <param name="UserName">用户名</param>
/// <param name="UserPwd">密码</param>
/// <returns></returns>
[WebMethod]
public
XmlDataDocument GetUpMassageDate(
string
UserName,
string
UserPwd)
{
try
{
XmlDataDocument xd =
new
XmlDataDocument();
DataSet ds = DbHelperSQL.Query(
"select Mobile,UPMessge, RecordDate from dbo.NA_Activity_Data where ActivityID in( select ActivityID from dbo.NA_Activity where UserID in (select UserID from dbo.NA_User where UserName='"
+ UserName.Trim() +
"' and UserPwd='"
+ UserPwd.Trim() +
"'))"
);
if
(ds !=
null
&& ds.Tables.Count > 0)
{
xd =
new
XmlDataDocument(ds);
XmlNode root1 = xd.DocumentElement;
XmlNodeList roots = root1.SelectNodes(
"ds"
);
foreach
(XmlNode item
in
roots)
{
XmlNodeList list = item.SelectNodes(
"RecordDate"
);
ds.EnforceConstraints =
false
;
//如果需要修改xml里的数据 需要加上这句
foreach
(XmlNode node
in
list)
{
//这里是修改XML中 RecordDate的时间格式 原始格式是： <RecordDate>2012-04-20T16:16:00+08:00</RecordDate>
node.InnerText = Convert.ToDateTime(node.InnerText.ToString()).ToString(
"yyyy-MM-dd HH:mm"
);
}
}
return
xd;
}
else

return
null

}
}
catch
(Exception ex)

}
引用webservice返回XML数据，解析XML数据并绑定到GridView上
public
void
DateBind()
{
UpMassgeWebserive.GetDateUpMassageSoapClient um =
new
UpMassgeWebserive.GetDateUpMassageSoapClient();
DataSet ds =
new
DataSet();
XmlNode xmlNode1;
XmlDataDocument xd =
new
XmlDataDocument();
StringBuilder sb;
xmlNode1 = um.GetUpMassageDate(
"hzh"
,
"chinahzh"
);
if
(xmlNode1==
null
)
{
return
;
}
sb =
new
StringBuilder(xmlNode1.OuterXml);
if
(sb.ToString().Equals(
""
))
{
return
;
}
xd.LoadXml(sb.ToString());
ds.ReadXml(
new
XmlNodeReader(xd));
GridView1.DataSource = ds.Tables[0].DefaultView;
GridView1.DataBind();
