C# 泛型问题

[hot666aaam]

protected void InitDepartment(DAL.Department dept, TreeNode root)
{
DAL.Department[] subDepartments = dept.GetEnabledSubDepartments();

foreach (DAL.Department var in subDepartments)
{
TreeNode node = new TreeNode(var.Name, 1, 2);
node.Tag = var;

this.InitDepartment(var, node);

root.Nodes.Add(node);
}
}

请问这个用泛型怎么写啊 dept是个类
谢谢大大们 请赐教

List<subDepartments> list= dept.GetEnabledSubDepartments().ToList();

foreach (DAL.Department var in list)
{
TreeNode node = new TreeNode(var.Name, 1, 2);
node.Tag = var;
this.InitDepartment(var, node);
root.Nodes.Add(node);
}

interface IClassHaveName
{
    string Name { get; set; }
}

protected void InitDepartment<T>(T dept, TreeNode root) where T : IClassHaveName
  {
  T[] subDepartments = dept.GetEnabledSubDepartments();

  foreach (T item in subDepartments)
  {
  TreeNode node = new TreeNode(item.Name, 1, 2);
  node.Tag = item;

  this.InitDepartment(item, node);

  root.Nodes.Add(node);
  }
  }
 
class DAL.Department : IClassHaveName
{
    ...
}

这种时候感觉不太适合用泛型，因为你用到了类里的方法，并不是所有类里都有GetEnabledSubDepartments这种方法
这种时候用接口还好些

C# code
interface IClassHaveName
{
string Name { get; set; }
}

protected void InitDepartment<T>(T dept, TreeNode root) where T : IClassHaveName
{
T[] subDepartments = dept.GetEnabledSubDepa……

IClassHaveName里面少了个GetEnabledSubDepartment方法
