C＃的匿名类型不能被分配​​到 - 它是只读 [英] C# Anonymous types cannot be assigned to -- it is read only

问题描述

什么是错的这个代码片断？

What is wrong with this code-snippet?

class Program
{
    static void Main(string[] args)
    {
        var obj = new { Name = "A", Price = 3.003 };

        obj.Name = "asdasd";
        obj.Price = 11.00;

        Console.WriteLine("Name = {0}\nPrice = {1}", obj.Name, obj.Price);

        Console.ReadLine();
    }
}

我收到以下错误：

I am getting the following errors:

Error   5   Property or indexer 'AnonymousType#1.Name' cannot be assigned to -- it is read only .....\CS_30_features.AnonymousTypes\Program.cs  65  13  CS_30_features.AnonymousTypes
Error   6   Property or indexer 'AnonymousType#1.Price' cannot be assigned to -- it is read only    .....\CS_30_features.AnonymousTypes\Program.cs  66  13  CS_30_features.AnonymousTypes

如何重新设定值变成一个匿名类型的对象？

How to re-set values into an anonymous type object?

推荐答案

匿名类型在C＃中是不可变的，因此不具有财产setter方法​​。你需要创建一个新的anonmyous类型的值

Anonymous types in C# are immutable and hence do not have property setter methods. You'll need to create a new anonmyous type with the values

obj = new { Name = "asdasd", Price = 11.00 };
