c# 3.0 - C# Anonymous types cannot be assigned to -- it is read only

Question

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}
Price = {1}", obj.Name, obj.Price);

        Console.ReadLine();
    }
}

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.AnonymousTypesProgram.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.AnonymousTypesProgram.cs  66  13  CS_30_features.AnonymousTypes

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

Answer 1

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 };
