C# 使用XmlSerializer C将数据从XML加载到类#

我有一个如下所示的XML

<?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>

我的问题

---

已为

节点和

节点正确加载数据。但是，

节点的数据根本没有加载。它总是空的

为了从另一个列表中的列表获取数据，我还需要添加其他内容吗

---

有什么我错过的吗

其中一个属性命名不正确-名称必须与父节点名称匹配。 您有

，所以属性的名称应该相同。因此，改变这一行：

public List<Group> PermissionGroups

公共列表权限组

对此

public List<Group> Permissions

公共列表权限

使用这些类，我能够正确地反序列化XML：

测试代码：

string xml = @"<?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"">

    </Group>

RoleManagement roleManagement;

// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(xml);

using (MemoryStream stream = new MemoryStream(byteArray))
{
    XmlSerializer serializer = new XmlSerializer(typeof(RoleManagement));

    using (XmlReader reader = XmlReader.Create(stream))
    {
        roleManagement = (RoleManagement)serializer.Deserialize(reader);
    }
}

stringxml=@”
";
角色管理角色管理；
//将字符串转换为流
byte[]byteArray=Encoding.UTF8.GetBytes（xml）；
使用（MemoryStream stream=新的MemoryStream（byteArray））
{
XmlSerializer serializer=新的XmlSerializer（typeof（RoleManagement））；
使用（XmlReader=XmlReader.Create（stream））
{
roleManagement=（roleManagement）序列化程序。反序列化（读取器）；
}
}

如何从文件反序列化？我可以在Visual Studio for xml中通过“特殊粘贴”生成这些类。但是我想指定我自己的班级名称，非常感谢。这就是我所怀念的。

string xml = @"<?xml version=""1.0"" encoding=""utf-8""?>

using (MemoryStream stream = new MemoryStream(byteArray))
