C# 如何访问ObservableCollection中对象的属性？

我有一个通用的可观察集合

public ObservableCollection<T> _DGModels;

---

我的问题是如何使用Type.GetProperty（）访问Number的属性，即FirstName或LastName

要使用反射获取属性

FirstName

（或

LastName

）的值，只需按要求使用

GetProperty（）

，如下所示：

Number num = new Number() { FirstNumber = 1, LastNumber = 5 };

int first = (int)num.GetType().GetProperty("FirstNumber").GetValue(num,null);

Console.WriteLine(first);

public class Number : INotifyPropertyChanged
{
    public int FirstNumber { get; set; }
    public int LastNumber { get; set; }
    public int PlusNumber { get; set; }

    public event PropertyChangedEventHandler PropertyChanged;

    public void NotifyPropertyChanged(string propertyName)
    { 
        //... 
    }
}

假设您的

Number

类如下所示：

Number num = new Number() { FirstNumber = 1, LastNumber = 5 };

int first = (int)num.GetType().GetProperty("FirstNumber").GetValue(num,null);

Console.WriteLine(first);

public class Number : INotifyPropertyChanged
{
    public int FirstNumber { get; set; }
    public int LastNumber { get; set; }
    public int PlusNumber { get; set; }

    public event PropertyChangedEventHandler PropertyChanged;

    public void NotifyPropertyChanged(string propertyName)
    { 
        //... 
    }
}

什么是GetProperty（）？
