This is XML Document.I want to bind XML data to GridView using Linq to XML .I want data from title_rec element.There are near about 94 records. :-

我创建了类TitleByApn＆amp;将Linq写入XML查询以解析xml数据。请查找下面的类详细信息和返回查询输出的代码。请使用此代码，或者如果您可以为我提供其他具有不同逻辑的代码也可以。
public class TitleByApn
{
private string grantor;
private string grantee;
private string doctype;
private string instrument;
private string month;
private string day;
private string year;
private string remarks;
public string _grantor
{ get { return grantor; }
}
public string _grantee
{
get {return grantee ;}
}
public string _month
{
get {return month; }
}
public string _day
{
get {return day; }
}
public string _year
{
get { return year; }
}
public string _doctype
{
get{ return doctype; }
}
public string _remarks
{
get {return remarks;}
}
public string _instrument
{
get {return instrument; }
}
public static List<TitleByApn> GetTitle()
{
List<TitleByApn> output = new List<TitleByApn>();
string filepath = @"C:/Title.xml";
//XElement xdoc = new XElement();
XElement xdoc = XElement.Load(filepath);
//XElement xElement = XElement.Parse(filepath);
//var query = from b in xdoc.Descendants("title_doc")
// select b.Value;
//string query = (from b in xdoc.Descendants("title_doc")
// select b.Value).FirstOrDefault();
int i = 0;
string s1 = "";
string inst = "";
//string s2 = "";
//string s3 = "";
//string s4 = "";
var authorList = xdoc.Descendants("title_doc").Select(x => x.Value).ToList();
foreach (string item in authorList)
{
string Month = (from o in xdoc.Descendants("title_doc").Descendants("recorded")
select o.Element("month").Value).First();
string Day = (from o in xdoc.Descendants("title_doc").Descendants("recorded")
select o.Element("day").Value).First();
string Year = (from o in xdoc.Descendants("title_doc").Descendants("recorded")
select o.Element("year").Value).First();
string granTor = (from o in xdoc.Descendants("title_doc").Descendants("party_info").Descendants("party")
where o.Attribute("role").Value == "GRANTOR"
select o.Element("name").Value).FirstOrDefault();
////select new Instrument()
////{
//// Grantor = (string)o.Element("name")
////};
string granTee = (from o in xdoc.Descendants("title_doc").Descendants("party_info").Descendants("party")
where o.Attribute("role").Value == "GRANTEE"
select o.Element("name").Value).First();
string Doctype =(from o in xdoc.Descendants("title_doc").Descendants("inst")
select o.Element("type").Value).First();
string instNo = (from o in xdoc.Descendants("title_doc").Descendants("inst")
select o.Element("number").Value).First();
string REmarks = (from o in xdoc.Descendants("title_doc").Descendants("remarks")
select o.Element("text").Value).First();
output.Add(new TitleByApn(granTor, granTee, Month, Day, Year,instNo, Doctype, REmarks));
}
return output;
}
}
This is the code responsible to bind the class to gridview:
GridView1.DataSource = TitleByApn.GetTitle();
GridView1.DataBind();
I know because of FirstOrDefault() only first record is displaying in gridview.
I want code to display all the records in gridview.
Please help me ASAP.
Thanks in advance.

根据您问题的内容，听起来您已经解析了XML并将其放入上面创建的类中。在Codeplex上发现的本教程标题为“A Detailed Data Binding Tutorial ”，详细介绍了如何将类绑定到带有访问修饰符的DataGridView等等。
基本上，一旦创建了GridView，就可以将BindingSource对象添加到它的数据项中，并简单地添加XML类信息：
private void Form1_Load(object sender, EventArgs e)
{
airplaneBindingSource.Add(new Airplane("Boeing 747", 800));
airplaneBindingSource.Add(new Airplane("Airbus A380", 1023));
airplaneBindingSource.Add(new Airplane("Cessna 162", 67));
}
