Question

我正在尝试更改类对象中的值。是否有任何这样做。我正在尝试在UI中动态显示更新。（xaml）

我的课程：

 public class Students
 {
    public int id;
    public string Name;
    public int Age; 
 }


//Students studs = new Students();
public ObservableCollection<Students> studs = new ObservableCollection<Students>();
Students studs_temp = sender as Students; // Read data in tapped function
int index = studs.IndexOf();
//Here I need to alter the Age of Student in studs where the id
 is equal to  id in studs_temp.

这样的事情：

public class Student
{
    public int id;
    public string Name;
    public int Age; 
}

在你的消费方法中：

List<Student> students = new List<Student>();
// ...
// populate your list
// ...

// select the student with a particular ID
Student s = students.Single(x => x.id == myID);
// now alter the age of that student
s.Age = 23;
