c# - Find type of nullable properties via reflection

Question

I examine the properties of an object via reflection and continue processing the data type of each property. Here is my (reduced) source:

private void ExamineObject(object o)
{
  Type type = default(Type);
  Type propertyType = default(Type);
  PropertyInfo[] propertyInfo = null;

  type = o.GetType();

  propertyInfo = type.GetProperties(BindingFlags.GetProperty |
                                    BindingFlags.Public |
                                    BindingFlags.NonPublic |
                                    BindingFlags.Instance);
  // Loop over all properties
  for (int propertyInfoIndex = 0; propertyInfoIndex <= propertyInfo.Length - 1; propertyInfoIndex++)
  {
    propertyType = propertyInfo[propertyInfoIndex].PropertyType;
  }
}

My problem is, that I newly need to handle nullable properties, but I have no clue how to get the type of a nullable property.

Answer 1

possible solution:

    propertyType = propertyInfo[propertyInfoIndex].PropertyType;
    if (propertyType.IsGenericType &&
        propertyType.GetGenericTypeDefinition() == typeof(Nullable<>))
    {
      propertyType = propertyType.GetGenericArguments()[0];
    }
