nhibernate mapping list of strings

Question

I have entity SampleObject with following properties

SampleObject.cs
    Guid Id {get; set;}
    string Name {get; set;}
    IList<string> Images {get; set;}

I tried to map these ImagePathUrls property like these

Map(x => x.Images, ("ImagePathUrl")).Length(255);

Ofcourse on database side I have table with column ImagePathUrl of type nvarchar 255.

On debugging I getting following error

Could not determine type for: System.Collections.Generic.IList`1
[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, 
PublicKeyToken=b77a5c561934e089]], mscorlib, Version=4.0.0.0, Culture=neutral, 
PublicKeyToken=b77a5c561934e089, for columns: NHibernate.Mapping.Column(ImagePathUrl)

You are mapping List to string column.

HasMany(x => x.Images).WithKeyColumn("SampleObjectId").WithTableName("SampleObjectImages").AsElemen‌t("ImagePathUrl");
