How could I avoid this dictionary (or create it dynamically)?
Dictionary<Type,Type> CorrespondingNullableType = new Dictionary<Type, Type>
{
{typeof(bool), typeof(bool?)},
{typeof(byte), typeof(byte?)},
{typeof(sbyte), typeof(sbyte?)},
{typeof(char), typeof(char?)},
{typeof(decimal), typeof(decimal?)},
{typeof(double), typeof(double?)},
{typeof(float), typeof(float?)},
{typeof(int), typeof(int?)},
{typeof(uint), typeof(uint?)},
{typeof(long), typeof(long?)},
{typeof(ulong), typeof(ulong?)},
{typeof(short), typeof(short?)},
{typeof(ushort), typeof(ushort?)},
{typeof(Guid), typeof(Guid?)},
};
