使用 roslyn 获取属性类型的类型参数

Question

I'd like to determine the type parameter of a property represented as an IPropertySymbol with a generic type. More precisely, I'd like to know if a property is of type int or int?. property.Type.OriginalDefinition gives me that it is a System.Nullable<T> but I'd like to know if it is a Nullable<int> or something else. Is there any way I can do this?

Answer 1

You're looking for the TypeArguments property , which gives you exactly that.

Note that if the property is declared as Nullable<T> on a class with a generic type parameter, that will only give you a concrete type if your property symbol comes from a closed type (eg, SomeClass<int> rather than the SomeClass<> definition).
