what is different propertyInfo.PropertyType and propertyInfo.GetType

It returns different data between propertyInfo.PropertyType and propertyInfo.GetType().

I want to know what different it is

var propInfo = dataModel.GetProperty("List<string>");

var test1 = propinfo.GetType().IsGenericType; // it returns false;
var test2 = propinfo.PropertyType.IsGenericType; // it returns true;

Please give me some idea.

Thank you.
