Write Extension Method as shown below:

public static class IgnoreReadOnlyExtensions
{
    public static IMappingExpression IgnoreReadOnly(
               this IMappingExpression expression)
    {
        var sourceType = typeof(TSource);

        foreach (var property in sourceType.GetProperties())
        {
            PropertyDescriptor descriptor = TypeDescriptor.GetProperties(sourceType)[property.Name];
            ReadOnlyAttribute attribute = (ReadOnlyAttribute) descriptor.Attributes[typeof(ReadOnlyAttribute)];
            if(attribute.IsReadOnly == true)
                expression.ForMember(property.Name, opt => opt.Ignore());
        }
        return expression;
    }
}

To call extension method:

Mapper.CreateMap().IgnoreReadOnly();
