Question

I know how to get an object properties using reflection:

var properties = typeof(T).GetProperties();

now how do I know if properties[0] is a string? or maybe it is a int? how can I know?

Answer 1

Each element of properties will be a PropertyInfo, which has a PropertyType property, indicating the type of the property.

So for example, you might use:

if (properties[0].PropertyType == typeof(string))

or if you wanted to check something in an inheritance-permitting way:

if (typeof(Stream).IsAssignableFrom(properties[0].PropertyType))
