Generics

So I'm new to generics. What I'm doing below is:

1) User creates a struct (or class...this example will only use struct)
Example:

C# Code:

struct UserInfo
    {
        public string FirstName;
        public string LastName;
        public string Department;
    }//end struct

2) User instantiates class (not important)
3) User calls method:

C# Code:

UserInfo user = profile.GetInfo<UserInfo>();

4) Method takes the struct and, based on the names of the members of the struct, fills the struct with data from the object (in this particular instance UserProfile [Microsoft.Office.Server.UserProfiles])

C# Code:

/// <summary>
/// Fills the class or stuct with information from the users profile.
/// </summary>
///<exception cref="ArgumentException">Thrown if the struct or object datamember names are invalid.</exception>
public T GetInfo<T>() where T : new()
{
    object returnValue = new T();
    Type type = typeof(T);
 
    try
    {
        FieldInfo[] fields = type.GetFields();
        PropertyInfo[] properties = type.GetProperties();
 
        if (fields.Length > 0)
        {
            foreach (FieldInfo field in fields)
            {
                field.SetValue(returnValue, this.Profile[field.Name].Value);
            }//end foreach
        }
        else if (properties.Length > 0)
        {
            foreach (PropertyInfo property in properties)
            {
                property.SetValue(returnValue, this.Profile[property.Name].Value, null);
            }//end foreach
        }//end if
    }
    catch (Microsoft.Office.Server.UserProfiles.PropertyNotDefinedException)
    {
        throw new System.ArgumentException("Struct or Class member names do not match the options available. Run ListPossibleMembers() to get a list of members");
    }
    catch (Exception)
    {
       throw;
    }//end try/catch
    return (T)returnValue;
}//end GetInfo

Unknown members in code shown (class-level variables):
1. "profile" -- UserProfile that gets instantiated in the constructor

I built this because I've found myself constantly querying information about users in SharePoint. With this, all I need to do is create a struct or class with the datamembers, and then call the function.

Since this is my first foray into generics, I was hoping someone could take a look at the code and let me know if they see anything horribly wrong with this, or if they could give suggestions on a different way to accomplish it.
