我是Linq的新手.

我想在foreach语句中设置两个值,就像这样

我的实际代码就是这个

foreach (Employee emp in employees)
{
    foreach(Department dept in emp.Departments)
    {
        dept.SomeProperty = null;
    }
    collection.AddRange(emp.Departments);              
}

少量重构将上述内容转化为此

foreach (Employee emp in employees)
{
    emp.Departments.ToList().ForEach(u => u.SomeProperty = null))
    collection.AddRange(emp.Departments);              
}

但是我想要这样的东西

employees.ToList().Foreach(collection.AddRange(emp.Departments),
emp.Departments.ToList().ForEach(u => u.SomeProperty = null))
