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
Nullablefor example, or
int?`?
int?
=== Nullable<int>
. they are one in the same. If you want to know that what type the nullable is, then you can use Nullable.GetUnderlyingType(typeof(int?))
method to get the type (in this instance int
)
Nullable.GetUnderlyingType
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.
