C# Extrakt - XML ​​Child Node Attribute

Question

Beispiel für XML-Datei

<NvM_DataManager_Blocks 
     AlignmentConstraint="ManagedBy_DataManager" 
     GenerateBlockAccessAPI="Yes" UseProtectedSections="Yes" UseRteForDataManagerInterface="No"> 
     <DATA_MANAGER_EEPROM_BLOCK Block_Crc_Type="NVM_CRC16" 
      Block_Priority="255" Block_Type="NVM_BLOCK_NATIVE" 
      ErrorCallback="" FeeOrEa_BlockId="" 
      Name="DataManager_Block_01" 
      Project_specific_information="" 
      Resistant_To_Changed_SW="No" Storage_In="Fee" Write_Only_At_WriteAll="No"> 
      <DATA_ELEMENT CreateCommitedApi="Yes" DataSize="" 
       DataSize_bit="" Data_type="uint8" Default_Value="66" 
       Header_file="" Name="DataManager_DataElement_01" 
       Number_Of_Planned_Writes="255" VariantInit="No"/> 
      <DATA_ELEMENT CreateCommitedApi="Yes" DataSize="" 
       DataSize_bit="" Data_type="uint32" 
       Default_Value="255" Header_file="" 
       Name="DataManager_DataElement_02" 
       Number_Of_Planned_Writes="363" VariantInit="No"/> 
     </DATA_MANAGER_EEPROM_BLOCK>

Dies ist mein Code.

//Load xml 

XDocument xdoc = XDocument.Load("C:\\Users\\John\\Desktop\\Program\\file.xml"); 
var blocks2 = (from r in xdoc.Descendants("DATA_MANAGER_EEPROM_BLOCK") 
       select new 
       { 
        Name = r.Attribute("Name").Value, 

//This line below does not the produce what is req. I need some help on how to fix this. 

        Sub_Elements = xdoc.Descendants("DATA_MANAGER_EEPROM_BLOCK").Descendants("DATA_ELEMENT") 

       }).ToList(); 

Allerdings habe ich einige Frage, die Unterelemente zu extrahieren: DataManager_DataElement_01 & DataManager_DataElement_02 und deren Attribute.
