Load data from XML to Class using XmlSerializer C#

Question

I have an XML as shown below.

<?xml version="1.0" encoding="utf-8"?>
<RoleManagement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Permissions>
    <Group Name="Test Case Management">
      <Permission ID="1" Name="Add/Edit/Delete test cases" />
      <Permission ID="2" Name="Assign Test cases to users" />
    </Group>
    <Group Name="Bug Management">
      <Permission ID="9" Name="Add/Edit/Delete bugs" />
      <Permission ID="13" Name="View bugs" />
    </Group>
    <Group Name="Administration">
      <Permission ID="19" Name="Database backup" />
      <Permission ID="20" Name="Role Management" />
    </Group>
  </Permissions>
  <RolePermissions>
    <RolePermission RedmineId="8" PermissionID="9" />
    <RolePermission RedmineId="8" PermissionID="13" />
  </RolePermissions>
  <Roles>
    <Role Name="Manager" RedmineId="8" TestlinkId="15" />
  </Roles>
</RoleManagement>

I need to load the data from xml to C# classes using XmlSerializer.

What I have done so Far

I have created these classes.

    [Serializable()]
    [System.Xml.Serialization.XmlType(AnonymousType = true)]
    [System.Xml.Serialization.XmlRoot(Namespace = "", IsNullable = false)]
    public partial class RoleManagement
    {
        private List<Group> permissionGroupsField;
        private List<RolePermission> rolePermissionsField;
        private List<Role> rolesField;
        [System.Xml.Serialization.XmlArrayItem("Group", IsNullable = false)]
        public List<Group> PermissionGroups
        {
            get { return this.permissionGroupsField; }
            set { this.permissionGroupsField = value; }
        }
        [System.Xml.Serialization.XmlArrayItem("RolePermission", IsNullable = false)]
        public List<RolePermission> RolePermissions
        {
            get { return this.rolePermissionsField; }
            set { this.rolePermissionsField = value; }
        }
        [System.Xml.Serialization.XmlArrayItem("Role", IsNullable = false)]
        public List<Role> Roles
        {
            get { return this.rolesField; }
            set { this.rolesField = value; }
        }
    }

    [Serializable()]
    [System.Xml.Serialization.XmlType(AnonymousType = true)]
    public partial class Group
    {
        private List<Permission> permissionsField;
        private string nameField;
        [System.Xml.Serialization.XmlElement("Permission")]
        public List<Permission> Permissions
        {
            get { return this.permissionsField; }
            set { this.permissionsField = value; }
        }
        [System.Xml.Serialization.XmlAttribute("Name")]
        public string GroupName
        {
            get { return this.nameField; }
            set { this.nameField = value; }
        }
    }

    [Serializable()]

        private string nameField;
        [System.Xml.Serialization.XmlAttribute()]
        public int ID
        {
            get { return this.idField; }
            set { this.idField = value; }
        }
        [System.Xml.Serialization.XmlAttribute()]
        public string Name
        {
            get { return this.nameField; }
            set { this.nameField = value; }
        }
    }

    [Serializable()]
    [System.Xml.Serialization.XmlType(AnonymousType = true)]
    public partial class RolePermission
    {
        private int redmineIdField;
        private int permissionIDField;
        [System.Xml.Serialization.XmlAttribute()]
        public int RedmineId
        {
            get { return this.redmineIdField; }
            set { this.redmineIdField = value; }
        }
        [System.Xml.Serialization.XmlAttribute()]
        public int PermissionID
        {
            get { return this.permissionIDField; }
            set { this.permissionIDField = value; }
        }
    }

    [System.Xml.Serialization.XmlType(AnonymousType = true)]
    public partial class Role
    {
        private string nameField;
        private int redmineIdField;
        private int testlinkIdField;
        [System.Xml.Serialization.XmlAttribute()]
        public string Name
        {
            get { return this.nameField; }
            set { this.nameField = value; }
        }
        [System.Xml.Serialization.XmlAttribute()]
        public int RedmineId
        {
            get { return this.redmineIdField; }
            set { this.redmineIdField = value; }
        }
        [System.Xml.Serialization.XmlAttribute()]
        public int TestlinkId
        {
            get { return this.testlinkIdField; }
            set { this.testlinkIdField = value; }
        }
    }

My Problem

---

Data is correctly loaded for <RolePermissions> node and <Roles> node. But data for <Permissions> node are not loading at all. Its always null.

Is there anything else i need to add to get data from list inside another list?

Is there anything I miss?

Answer 1

One of the properties is named incorrectly - name must match parent node name. You have <Permissions> so property should be named same. So change this line:

public List<Group> PermissionGroups

to this

public List<Group> Permissions
