Create code at runtime with Reflection in .NET C#: Fields

In the previous post of this short series we saw how to create a method using Reflection.

We can also create fields in our custom type. Here’s how to create a standard private field:

FieldBuilder fieldBuilder = simpleType.DefineField("_price", typeof(int), FieldAttributes.Private);

You can use the FieldAttributes enumeration to modify the properties of the field. E.g. here’s how to declare the field public and readonly – which is not a very clever combination, but there you have it:

FieldBuilder fieldBuilder = simpleType.DefineField("_price", typeof(int), FieldAttributes.InitOnly | FieldAttributes.Public);
