结合元组的列表 [英] binding to a list of tuples

问题描述

我的元组配对两个数据的列表...我想列表绑定到数据网格。对于显示器，它工作正常......但如果我尝试和修改一个条目，它说：一个双向或者OneWayToSource结合不能在只读属性项目1工作......想必元组是在.NET 4.0中不可改变的。有没有绑定到两双数据，而无需创建一个可变的元组类我自己的一个简单的方法？

I have a list of tuples pairing two pieces of data... I'd like to bind the list to a data grid. For display, it works fine... but if I try and modify an entry, it says "A TwoWay or OneWayToSource binding cannot work on the read-only property 'Item1'"... presumably Tuples are immutable in .NET 4.0. Is there an easy way to bind to pairs of data without creating a mutable tuple class of my own?

推荐答案

是，元组是不可改变的。匿名类型也是不可改变的。你应该用你自己的泛型类型：

Yes, tuples are immutable. Anonymous types are also immutable. You should use your own generic type:

public class Pair<T, U> 
{
     public Pair() {
     }

     public Pair(T first, U second) {
       this.First = first;
       this.Second = second;
     }

     public T First { get; set; }
     public U Second { get; set; }
};
