如何将Expression <Func <T,DateTime >>转换为Expression <Func <T,object >>

public static Expression<Func<T, object>> ConvertExpression<T>(Expression<Func<T, DateTime>> expression)
{
    // 创建一个新的委托类型
    var newDelegateType = typeof(Func<,>).MakeGenericType(typeof(T), typeof(object));

    // 创建一个新的Lambda表达式
    var newExpression = Expression.Lambda(newDelegateType, expression.Body, expression.Parameters);

    // 返回新的Lambda表达式
    return (Expression<Func<T, object>>)newExpression;
}
