.netCore MVC单一条件分页
直白点，呈上香喷喷的代码，创建AspNetCoreMvcPager类,直接把下面代码复制进去就行
public static class PagedList<T> { public static Tuple<List<T>, PagerModel> PageList(int pageindex, int pagesize, List<T> list) { int count = list.Count(); int num = (count % pagesize == 0) ? (count / pagesize) : (count / pagesize + 1); List<T> list2 = Enumerable.ToList<T>(Enumerable.Take<T>(Enumerable.Skip<T>(list, (pageindex - 1) * pagesize), pagesize)); PagerModel pagerModel = new PagerModel(); pagerModel.pageIndex = pageindex; pagerModel.pageCount = num; pagerModel.Count = count; pagerModel.pageStart = ((pageindex - 2 > 0) ? (pageindex - 2) : 1); pagerModel.pageEnd = ((pageindex + 2 >= num) ? num : (pagerModel.pageStart + 4)); return new Tuple<List<T>, PagerModel>(list2, pagerModel); } } public static class PagerHtmlString { public static IHtmlContent Pager(PagerModel model, string controllerName, string actionName, bool Total) { StringBuilder stringBuilder = new StringBuilder(); stringBuilder.Append(string.Concat(new object[] { "<a class='page_first nopage' href=\"/", controllerName, "/", actionName, "?pageindex=", 1, "\">首页</a>" })); stringBuilder.Append(string.Concat(new object[] { "<a class='prev nopage' href=\"/", controllerName, "/", actionName, "?pageindex=", (model.pageIndex == 1) ? 1 : (model.pageIndex - 1), "\">上一页</a>" })); //stringBuilder.Append("</li>"); for (int i = model.pageStart; i <= model.pageEnd; i++) { //stringBuilder.Append("<li class=" + ((model.pageIndex == i) ? "active" : "") + ">"); if (model.pageIndex == i) { stringBuilder.Append(string.Concat(new object[] { "<span style='margin-left:4px; ' class='current " + ((model.pageIndex == i) ? "cur" : "")+"' 'href=\"/'", controllerName, "/", actionName, "?pageindex=", i, "\">", ""+i+"" + "</span>" })); } else { stringBuilder.Append(string.Concat(new object[] { "<a style='margin-left:4px; ' href=\"/", controllerName, "/", actionName, "?pageindex=", i, "\">", ""+i+"" + "</a>" })); } } stringBuilder.Append(string.Concat(new object[] { "<a class='next' style='margin-left:4px; ' href=\"/", controllerName, "/", actionName, "?pageindex=", (model.pageIndex == model.pageCount) ? model.pageCount : (model.pageIndex + 1), "\">下一页</a>" })); stringBuilder.Append(string.Concat(new object[] { "<a class='page_last' style='margin-left:4px; ' href=\"/", controllerName, "/", actionName, "?pageindex=", model.pageCount, "\">尾页</a>" })); bool flag = model.Count > 0; IHtmlContent result; if (flag) { result = new HtmlString(stringBuilder.ToString()); } else { result = new HtmlString(""); } return result; } public static IHtmlContent PagerSearch(PagerModel model, string controllerName, string actionName, bool Total) { StringBuilder stringBuilder = new StringBuilder(); string strSearch = ""; if (model.search.SerachName!="") { strSearch = strSearch + "&SearchName=" + model.search.SerachName; } if (model.search.rdata != "") { strSearch = strSearch + "&rdata=" + model.search.rdata; } if (model.search.sporttype >0) { strSearch = strSearch + "&sporttype=" + model.search.sporttype; } if (model.search.FileType >0) { strSearch = strSearch + "&FileType=" + model.search.FileType; } if (model.search.SubType>0) { strSearch = strSearch + "&SubType=" + model.search.SubType; } stringBuilder.Append(string.Concat(new object[] { "<a class='page_first nopage' href=\"/", controllerName, "/", actionName, "?pageindex=", 1,strSearch, "\">首页</a>" })); stringBuilder.Append(string.Concat(new object[] { "<a class='prev nopage' href=\"/", controllerName, "/", actionName, "?pageindex=", (model.pageIndex == 1) ? 1 : (model.pageIndex - 1),strSearch, "\">上一页</a>" })); for (int i = model.pageStart; i <= model.pageEnd; i++) { if (model.pageIndex == i) { stringBuilder.Append(string.Concat(new object[] { "<span style='margin-left:4px; ' class='current " + ((model.pageIndex == i) ? "cur" : "")+"' 'href=\"/'", controllerName, "/", actionName, "?pageindex=", i,strSearch, "\">", ""+i+"" + "</span>" })); } else { stringBuilder.Append(string.Concat(new object[] { "<a style='margin-left:4px; ' href=\"/", controllerName, "/", actionName, "?pageindex=", i,strSearch, "\">", ""+i+"" + "</a>" })); } } stringBuilder.Append(string.Concat(new object[] { "<a class='next' style='margin-left:4px; ' href=\"/", controllerName, "/", actionName, "?pageindex=", (model.pageIndex == model.pageCount) ? model.pageCount : (model.pageIndex + 1),strSearch, "\">下一页</a>" })); stringBuilder.Append(string.Concat(new object[] { "<a class='page_last' style='margin-left:4px; ' href=\"/", controllerName, "/", actionName, "?pageindex=", model.pageCount,strSearch, "\">尾页</a>" })); bool flag = model.Count > 0; IHtmlContent result; if (flag) { result = new HtmlString(stringBuilder.ToString()); } else { result = new HtmlString(""); } return result; } } public class PagerModel { public int pageIndex { get; set; } public int pageCount { get; set; } public int Count { get; set; } public int pageStart { get; set; } public int pageEnd { get; set; } public SearchInput search { get;set; } } //条件类型 public class SearchInput { //搜索 public string SerachName { get; set; } //日期 public string rdata { get; set; } //文件类型ID public int FileType { get; set; } //运动类型ID public int sporttype { get; set; } //子类ID public int SubType { get; set; } }
创建完分页类后，直接在 Controller中使用,如下
using AspNetCoreMvcPager;//引用 /// <summary> /// 活动列表 /// </summary> /// <returns></returns> public async Task<IActionResult> StudentList(string SearchName = "",int PageIndex = 1) { SearchDto search = new SearchDto() { PageIndex = PageIndex,//当前页 Pagesize = 10，//分页数 }; //获取数据 var tactivitiesList = await _tactivitiesManager.GettactivityList(); var pagedList = PagedList<StudentModel>.PageList(search.PageIndex, search.Pagesize, tactivitiesList); //组装参数 pagedList.Item2.pageIndex = pageindex; SearchInput input = new SearchInput() { SerachName = SearchName }; pagedList.Item2.search = input; ViewBag.model = pagedList.Item2; return View(pagedList.Item1); }
在页面代码如下
@using AspNetCoreMvcPager;
<div class="turnpage"> @Html.Raw(PagerHtmlString.Pager(ViewBag.model, "Activities", "ActivityList", true)) </div>
执行效果图(需要自己写css样式进行控制):
