xmlファイルからgridview asp.netに特定のレコードをフィルタリングします。

Question

従業員のデータを含むXMLファイルがあります。私のページのデザインは、ユーザーが自分のIDを入力すると、グリッドビューはスキル（すでに存在する場合）を表示し、何も表示せずに自分のデータ（新入社員）を入力するようになります。私は彼のIDを使用して従業員のデータを記録し、グリッドビューで表示したいと思います。しかし、私のコードを使用すると、「 'System.Data.DataRow'に 'EmployeeID'という名前のプロパティが含まれていません」という例外がスローされます。私はすでに正しい値でテンプレートを境界しています。何が問題なのでしょう？

私のXMLスキーマ

-<SkillSet> 


-<SkillSets> 

<EmployeeID>1</EmployeeID> 

<EmployeeName>abc</EmployeeName> 

<PLName>xyz</PLName> 

<SkillName1>Html</SkillName1> 

<SkillType1>Programming</SkillType1> 

<SkillProficiency1>Beginner</SkillProficiency1> 

<Experience1>1</Experience1> 

<Comments>Hello</Comments> 

</SkillSets> 

</SkillSet> 

私のaspxページのソースコード：

           <ItemTemplate> 
            <asp:Label ID="lblEmpId" runat="server" Text='<%# Bind("EmployeeID")%>'></asp:Label> 
           </ItemTemplate> 
          </asp:TemplateField>

          </asp:TemplateField> 
         </Columns>      
        </asp:GridView> 

結合グリッドのための私のC＃コード：

private void BindGrid() 
    { 

     string filename = Server.MapPath("~/SkillSet.xml"); 

     if (File.Exists(filename) == true) 
     { 
      try 
      { 

       string filePath = Server.MapPath("SkillSet.xml"); 
       DataSet ds = new DataSet(); 
       ds.ReadXml(filePath); 
       var skillSets = ds.Tables[0].AsEnumerable(); 
       var query = from SkillSets in skillSets 
          where SkillSets.Field<string>("EmployeeID") == emplid 
          select SkillSets; 
       grdxml.DataSource = query.ToList(); 
       grdxml.DataBind(); 
      } 
      catch (Exception ex) 
      { 
       lblerror.Text = ex.ToString(); 
      } 
     } 
    }

私はこれをテストし、その正常に動作しています

var xmlStr = File.ReadAllText(Server.MapPath("YourFileName.xml")); 
var str = XElement.Parse(xmlStr); 
var result = str.Elements("SkillSets").Where(x => x.Element("EmployeeID").Value.Equals(emplid.ToString())).ToList();  
List<Employee> mapList = new List<Employee>(); 
foreach (var item in result) 
{ 
    Employee obj = new Employee(); 
    obj.EmployeeID = item.Element("EmployeeID").Value; 
    obj.EmployeeName = item.Element("EmployeeName").Value; 
    obj.PLName = item.Element("PLName").Value; 
    obj.SkillName1 = item.Element("SkillName1").Value; 
    obj.SkillType1 = item.Element("SkillType1").Value; 
    obj.SkillProficiency1 = item.Element("SkillProficiency1").Value; 
    obj.Experience1 = item.Element("Experience1").Value; 
    obj.Comments = item.Element("Comments").Value; 
    mapList.Add(obj); 
} 

grdxml.DataSource = mapList; 
grdxml.DataBind(); 

そして、あなたはEmployeeのクラスを作成することができます。

public class Employee 
    { 
    private string _EmployeeID; 
    public string EmployeeID 
    { 
     get 
     { 
      return _EmployeeID; 
     } 
     set 
     { 
      _EmployeeID = value; 
     } 

    } 
    private string _EmployeeName; 
    public string EmployeeName 
    { 
     get 
     { 
      return _EmployeeName; 
     } 
     set 
     { 
      _EmployeeName = value; 
     } 
    } 
    private string _PLName; 
    public string PLName 
    { 
     get 
     { 
      return _PLName; 
     } 
     set 
     { 
      _PLName = value; 
     } 
    } 

    private string _SkillName1; 
    public string SkillName1 
    { 
     get 
     { 
      return _SkillName1; 
     } 
     set 
     { 
      _SkillName1 = value; 
     } 
    } 

    private string _SkillType1; 
    public string SkillType1 
    { 
     get 
     { 
      return _SkillType1; 
     } 
     set 
     { 
      _SkillType1 = value; 
     } 
    } 

    private string _SkillProficiency1; 
    public string SkillProficiency1 
    { 
     get 
     { 
      return _SkillProficiency1; 
     } 
     set 
     { 
      _SkillProficiency1 = value; 
     } 
    } 

    private string _Experience1; 
    public string Experience1 
    { 
     get 
     { 
      return _Experience1; 
     } 
     set 
     { 
      _Experience1 = value; 
     } 
    } 

    private string _Comments; 
    public string Comments 
    { 
     get 
     { 
      return _Comments; 
     } 
     set 
     { 
      _Comments = value; 
     } 
    } 
}
