Property bag for C# class

Question

Accessing c# class properties like javascript language would make life a lot easier.

How we can do it in C#?

For example:

someObject["Property"]="simple string";
Console.WriteLine(someObject["FirstName"]);

Answer 1

dynamic keyword can be used instead

dynamic foo = ...
foo.Property = "simple string";
Console.WriteLine(foo.Property);

Answer 2

This code would work

dynamic user= new ExpandoObject();
user.name = "Anonymous";
user.id=1234
user.address="12 broad way"
user.State="NY"

import System.Dynamic namespace.

Answer 3

You could derive every single class from Dictionary<string, object>. But then, you could simply take JavaScript instead of misusing C#.

Answer 4

Here is how you can enable property-bag-like functionality in your classes by adding a few lines of code:

partial class SomeClass
{
    private static readonly PropertyDescriptorCollection LogProps = TypeDescriptor.GetProperties(typeof(SomeClass));

    public object this[string propertyName]
    {
        get { return LogProps[propertyName].GetValue(this); }
        set { LogProps[propertyName].SetValue(this, value); }
    }
}
