辅助方法不打印任何东西

Question

我在这个视图中创建了一个帮助方法：

@helper DisputeOpenedDays(DateTime createdDate)
    {

        TimeSpan difference = DateTime.Now.Subtract(createdDate);
        string.Format("0", difference.Days);
}

当我像这样使用它时

@DisputeOpenedDays(myobj.CreatedAt)

它不打印任何东西

Answer 1

尝试：

string.Format("{0}", difference.Days);

缺少花括号。

Answer 2

@helper DisputeOpenedDays(DateTime createdDate)
{
 TimeSpan difference = DateTime.Now.Subtract(createdDate);
 @string.Format("{0}", difference.Days);
}
