Dapper. Map to SQL Column with spaces in column names

Question

I\'ve managed to get something up and running today as small sandbox/POC project, but have seemed to bump my head on one issue...

Question:

Answer 1

I had a similar problem when trying to get mapped results from a call to the system sp_spaceused procedure. Marc's code didn't quite work for me as it complained about not being able to find a default constructor. I also made my version generic so it could theoretically be re-used. This may not be the fastest performing piece of code, but it works for me and in our situation these calls are made infrequently.

class TitleCaseMap : SqlMapper.ITypeMap where T: new()
{
    ConstructorInfo SqlMapper.ITypeMap.FindConstructor(string[] names, Type[] types)
    {
        return typeof(T).GetConstructor(Type.EmptyTypes);
    }

    SqlMapper.IMemberMap SqlMapper.ITypeMap.GetConstructorParameter(ConstructorInfo constructor, string columnName)
    {
        return null;
    }

    SqlMapper.IMemberMap SqlMapper.ITypeMap.GetMember(string columnName)
    {
        string reformattedColumnName = string.Empty;

        foreach (string word in columnName.Replace("_", " ").Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries))
        {
            reformattedColumnName += char.ToUpper(word[0]) + word.Substring(1).ToLower();
        }

        var prop = typeof(T).GetProperty(reformattedColumnName);

        return prop == null ? null : new PropertyMemberMap(prop);
    }

    class PropertyMemberMap : SqlMapper.IMemberMap
    {
        private readonly PropertyInfo _property;

        public PropertyMemberMap(PropertyInfo property)
        {
            _property = property;
        }
        string SqlMapper.IMemberMap.ColumnName
        {
            get { throw new NotImplementedException(); }
        }

        FieldInfo SqlMapper.IMemberMap.Field
        {
            get { return null; }
        }

        Type SqlMapper.IMemberMap.MemberType
        {
            get { return _property.PropertyType; }
        }

        ParameterInfo SqlMapper.IMemberMap.Parameter
        {
            get { return null; }
        }

        PropertyInfo SqlMapper.IMemberMap.Property
        {
            get { return _property; }
        }
    }
}
