如何在c＃中编写函数装饰器，如python

Question

我已经在python上工作了一段时间并返回到c＃项目。所以我习惯了python语言，这迫使我像一个python程序员一样思考，我喜欢这个！

我想问的问题是如何创建一个在其decarator之后调用的方法？

Python装饰器语法：

def p_decorate(func):
   def func_wrapper(name):
       return "<p>{0}</p>".format(func(name))
   return func_wrapper

@p_decorate
def get_text(name):
   return "lorem ipsum, {0} dolor sit amet".format(name)

我用谷歌搜索但只发现.Net Attributes并没有帮助我。

示例代码，但我想编写自己的授权属性类。

public class RestrictAccessToAssignedManagers : AuthorizationAttribute
{
    protected override AuthorizationResult IsAuthorized(System.Security.Principal.IPrincipal principal, AuthorizationContext authorizationContext)
    {
        EmployeePayHistory eph = (EmployeePayHistory)authorizationContext.Instance;
        Employee selectedEmployee;
        Employee authenticatedUser;

        using (AdventureWorksEntities context = new AdventureWorksEntities())
        {
            selectedEmployee = context.Employees.SingleOrDefault(e => e.EmployeeID == eph.EmployeeID);
            authenticatedUser = context.Employees.SingleOrDefault(e => e.LoginID == principal.Identity.Name);
        }

        if (selectedEmployee.ManagerID == authenticatedUser.EmployeeID)
        {
            return AuthorizationResult.Allowed;
        }
        else
        {
            return new AuthorizationResult("Only the authenticated manager for the employee can add a new record.");
        }
    }
}

[RestrictAccessToAssignedManagers]
public void InsertEmployeePayHistory(EmployeePayHistory employeePayHistory)
{
    if ((employeePayHistory.EntityState != EntityState.Detached))
    {
        this.ObjectContext.ObjectStateManager.ChangeObjectState(employeePayHistory, EntityState.Added);
    }
    else
    {
        this.ObjectContext.EmployeePayHistories.AddObject(employeePayHistory);
    }
}
