How to get string type for nullable types

c#, reflection

Solution

GetGenericArguments is the method you want.

if (item.PropertyType.IsGenericType) {
    if (item.PropertyType.GetGenericType() == typeof(Nullable<>)) {
        var valueType = item.PropertyType.GetGenericArguments()[0];
    }
}

On second thought though, Darren's answer is much simpler in this case as it will return null when you pass in a non-nullable type.

Problem

I'm generating a T4 template using the properties of my data class generated from my dbml files. To get the property type of the classes I use `item.PropertyType.Name`, the problem is that with nullable types it returns `Nullable` ``1`, is there a way to get`Nullable`for example, or`int?`?
