Handling complex types in UpdateAll()

[bernd70]

Hi,

I encountered a problem when trying to update an value contained in a complex type with UpdateAll(). The generated SQL statement is invalid, the "SET ..." portion is empty.

I tracked it down to GetPropertyName() in ExpressionHelper.cs. Here only the Member name is returned but not its fully qualified name if it is a complex type.

So I adjusted the function to return the fully qualified name of the member. This seems to work for me but since I am not using a lot of EFUtilities functions I am not 100% sure if my change has other (bad :-)) implications.

So here is my code for discussion:

` public static string GetPropertyName<TSource, TProperty>(this Expression<Func<TSource, TProperty>> propertyLambda)
{
Type type = typeof(TSource);

        var temp = propertyLambda.Body;
        while (temp is UnaryExpression)
        {
            temp = (temp as UnaryExpression).Operand;
        }

        return GetFullyQualifiedPropertyName(temp as MemberExpression);
    }

    private static string GetFullyQualifiedPropertyName(MemberExpression member)
    {
        MemberExpression parentMember = member.Expression as MemberExpression;

        if (parentMember != null)
            return GetFullyQualifiedPropertyName(parentMember) + "." + member.Member.Name;

        return member.Member.Name;
    }`
