我正在使用代码根据百分比值显示标签云。第一次将标记添加到我的数据库时，它看起来很大，然后相对于其他标记缩小（它们添加的次数越多）。这是代码：

然而，我想要做的是首先使标记变小（第一次添加），然后将其大小增加到所提及的次数。有谁知道我怎么做到这一点？非常感谢你的帮助！
答案 0 :(得分：0)
根据您显示的内容，标签应该已经显得很小 - tagGroup.Count（）将为1而GetTagSize将返回“small”
必须覆盖此代码以强制字体大小 - 只需将其取出即可，我认为您应该得到您所要求的内容。
答案 1 :(得分：0)
你为什么不接受这个：
weight = (((double)tagGroup.Count() / maxTagFrequencyNegative * 100) - 100) * -1
这样你就可以拿出最多的数字然后反转它们。
答案 2 :(得分：0)
我简化了你的代码以便在我的盒子上运行它。一切似乎都没问题。在这里，您可以看到我的测试页面：

我建议您稍微调试一下代码并检查所有数字是否正确。可能你在查询中遇到了一些问题（错误的连接或类似的东西），因为所有其他代码对我来说都很好。
希望这有帮助。
P.S。你可能在css中遇到问题吗？
