Map a Uri field using Dapper - dapper

Question

What is the cleanest way to map a string column to a Uri property using Dapper?
Here's the cleanest I've been able to come up with so far (using the ITypeMap functionality):
Query:
SELECT * FROM TableWithAStringAddressColumn
POCO:
public class MyPoco
{
[ColumnSetter("DapperAddress")]
public Uri Address { get; set; }
private string DapperAddress { set { this.Address = new Uri(value); } }
}
Extensions:
partial class SqlMapper
{
public static void InitializeTypeMaps()
{
SqlMapper.SetTypeMap(
typeof(MyPoco),
new CustomPropertyTypeMap(typeof(MyPoco), SqlMapper.CustomSetterMapper));
// call out every other class that needs this kind of mapping
}
public static Func<Type, string, PropertyInfo> CustomSetterMapper =
(type, columnName) =>
{
PropertyInfo prop = type
.GetProperties()
.FirstOrDefault(p => string.Equals(columnName, p.Name, StringComparison.OrdinalIgnoreCase));
if (prop != null)
{
// find out if we need to use a different setter
ColumnSetterAttribute setterAttribute = prop.GetCustomAttributes(false).OfType<ColumnSetterAttribute>().LastOrDefault();
if (setterAttribute != null)
{
PropertyInfo setterProp = type
.GetProperties(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance)
.FirstOrDefault(p => string.Equals(setterAttribute.Setter, p.Name, StringComparison.OrdinalIgnoreCase));
if (setterProp == null)
{
throw new InvalidOperationException(string.Format("Setter property misconfigured (Property={0}, Setter={1})", prop.Name, setterAttribute.Setter));
}
else
{
prop = setterProp;
}
}
}
return prop;
};
}
Custom Attribute:
public class ColumnSetterAttribute : Attribute
{
public string Setter { get; set; }
public ColumnSetterAttribute(string setter)
{
this.Setter = setter;
}
}
[edit] I'm looking for a solution I can use without needing to call out all columns in all my queries (I'd like to find a solution where I can use SELECT *).

Seems like a lot of work...
Wouldn't this be ok?
public class MyPoco
{
private string _uriMapper;
public Uri SomeUri
{
get { return new Uri(_uriMapper); }
}
public string Mapper { set { _uriMapper = value; } }
}
Edit:
public class UriContainer
{
private string _uriMapper;
public string UriMapper { set { _uriMapper = value; } }
public int Id { get; set; }
public Uri SomeUri { get {return new Uri(_uriMapper);} }
}
public class DbTests
{
[Test]
public void Can_Get_A_Uri()
{
using (var c = new SqlConnection("hello"))
{
c.Open();
var uri = c.Query<UriContainer>("select *, someuri as urimapper from uris where id = 3").Single();
Console.WriteLine(uri.SomeUri);
}
}
}
