使用Linq查詢Xml文件以獲取記錄

Question

以下是我的xml文件。 我必須為每個頁面和每個用逗號分隔的字符串中的Type提及字段。 請幫助如何繼續使用Linq

示例：如果我想為“ page1”定義“ Type = customFields”，則必須以逗號分隔的ProjectID，EmployeeID，EmployeeName，hasExpiration等獲取輸出

<Pages>
 <Page Name="Page1" >
<Type TypeID="customfields">
  <Field>ProjectID</Field>
  <Field>EmployeeID</Field>
  <Field>EmployeeName</Field>
  <Field>HasExpiration</Field>
  <Field>EndDate</Field>
</Type>
<Type TypeID="Directfields">
  <Field>ProjectID</Field>
  <Field>EmployeeID</Field>
  <Field>EmployeeName</Field>
  <Field>HasExpiration</Field>
  <Field>EndDate</Field>
  <Field>IsInUpdateMode</Field>
  <Field>TimesheetSpendLimit</Field>
</Type>
 </Page>
  <Page Name="Page2" >
    <Type TypeID="customfields">
  <Field>ProjectID</Field>
  <Field>EmployeeID</Field>
  <Field>EmployeeName</Field>
  <Field>HasExpiration</Field>
  <Field>EndDate</Field>
  <Field>IsInUpdateMode</Field>
  <Field>TimesheetSpendLimit</Field>
</Type>
<Type TypeID="Directfields">
  <Field>ProjectID</Field>
  <Field>EmployeeID</Field>
  <Field>EmployeeName</Field>
  <Field>HasExpiration</Field>
  <Field>EndDate</Field>
  <Field>IsInUpdateMode</Field>
  <Field>TimesheetSpendLimit</Field>
</Type>
  </Page>
</Pages>

Answer 1

您可以這樣做：

var Result = from a in element.Descendants("Page")
             from b in a.Descendants("Type")
             select new
             {
               Page = a.Attribute("Name").Value,
               Type = b.Attribute("TypeID").Value,
               Fields = String.Join(",", b.Elements("Field").Select(x => x.Value))
             };
foreach (var item in Result)
{
  Console.WriteLine(String.Format("Page = {0}:Type={1}:Fields:{2}", item.Page, item.Type, item.Fields));
}
