C# C语言中的动态分页
我是新来的 我的问题和马库斯的一样 我尝试执行的分页应该如下所示： 123456。。。101 当我点击数字5时，我希望它显示如下数字： 1。。。3 4 5 6 7 ... 101 当我在最后几页时，我希望它看起来与第一页相似： 1。。。96979899100101 粗体数字是您当前正在查看的页面 我希望这些点仅在有超过7页可用时才出现，如果没有，它应该看起来像一个正常的分页： 1234567 我没有加粗，而是添加了一些CSS 我的原始代码是这样的C# C语言中的动态分页,c#,loops,for-loop,pagination,paging,C#,Loops,For Loop,Pagination,Paging,我是新来的 我的问题和马库斯的一样 我尝试执行的分页应该如下所示： 123456。。。101 当我点击数字5时，我希望它显示如下数字： 1。。。3 4 5 6 7 ... 101 当我在最后几页时，我希望它看起来与第一页相似： 1。。。96979899100101 粗体数字是您当前正在查看的页面 我希望这些点仅在有超过7页可用时才出现，如果没有，它应该看起来像一个正常的分页： 1234567 我没有加粗，而是添加了一些CSS 我的原始代码是这样的 if (ListCount > ListP

约翰试试这样的。您需要根据需要进行定制

有大量的开源分页库。你可以考虑下载其中一个来查看它们是如何运行的。代码看起来很好，但是当你有很多页面要查看的时候。它将显示所有页面，如1-50它将显示所有1-50。。。我想要这样的东西，它会将数字与。。。分组的算法。。。有什么想法吗？就像1。。。3 4 5 6 7 ... 我更新了答案。这是一个工作样本，您可能需要根据需要进行定制。
