C# 为什么相同的ActionLink在“布局和控制器”中呈现方式不同；你的观点是什么？

我在.net核心mvc应用程序的两个部分中有相同的@Html.ActionLink，但为什么它们的呈现方式不同呢

启动：

endpoints.MapControllerRoute(
name: "products",
pattern: "product-category/{title}",
defaults: new { controller = "ProductCategories", action = "ProductsRelatedToCategory", pg = 1 });

public async Task<IActionResult> ProductsRelatedToCategory(int? cat, int? pg)
{
    // using cat to get which category is clicked and pg to get which page it is (in paginated list)
}

@Html.ActionLink(
    linkText,
    "ProductsRelatedToCategory",
    "ProductCategories",
    null,
    null,
    null,
    new { cat = 14, pg = 1, title = "power-tools" },
    new { @class = "menuProductLink" })

@Html.ActionLink(
    "Next",
    "ProductsRelatedToCategory",
    "ProductCategories",
    null,
    null,
    null,
    new { cat = productCategory.Id, pg = currentPage + 1, title = "power-tools" },
    new { @class = "paginate" })

行动：

endpoints.MapControllerRoute(
name: "products",
pattern: "product-category/{title}",
defaults: new { controller = "ProductCategories", action = "ProductsRelatedToCategory", pg = 1 });

public async Task<IActionResult> ProductsRelatedToCategory(int? cat, int? pg)
{
    // using cat to get which category is clicked and pg to get which page it is (in paginated list)
}

@Html.ActionLink(
    linkText,
    "ProductsRelatedToCategory",
    "ProductCategories",
    null,
    null,
    null,
    new { cat = 14, pg = 1, title = "power-tools" },
    new { @class = "menuProductLink" })

@Html.ActionLink(
    "Next",
    "ProductsRelatedToCategory",
    "ProductCategories",
    null,
    null,
    null,
    new { cat = productCategory.Id, pg = currentPage + 1, title = "power-tools" },
    new { @class = "paginate" })

按预期呈现权利：

“url 1”：{domain}/产品类别/电动工具？cat=14

在控制器视图（ProductsRelatedLocategory.cshtml）中用作分页中的下一页链接：

endpoints.MapControllerRoute(
name: "products",
pattern: "product-category/{title}",
defaults: new { controller = "ProductCategories", action = "ProductsRelatedToCategory", pg = 1 });

public async Task<IActionResult> ProductsRelatedToCategory(int? cat, int? pg)
{
    // using cat to get which category is clicked and pg to get which page it is (in paginated list)
}

@Html.ActionLink(
    linkText,
    "ProductsRelatedToCategory",
    "ProductCategories",
    null,
    null,
    null,
    new { cat = 14, pg = 1, title = "power-tools" },
    new { @class = "menuProductLink" })

@Html.ActionLink(
    "Next",
    "ProductsRelatedToCategory",
    "ProductCategories",
    null,
    null,
    null,
    new { cat = productCategory.Id, pg = currentPage + 1, title = "power-tools" },
    new { @class = "paginate" })

呈现不正确，如预期：

“url 2”：{domain}/ProductCategories/productsratedtocategory？cat=14&pg=2&title=power tools

---

两个url都工作正常，但实际上我想显示类似“url 1”的url，为什么它们呈现不同？

那么您的意思是要从url中删除

title=power tools

，但保留

pg

？您使用的是区域吗？您使用的是什么版本的ASP.NET Core？我已经使用v3.1测试了您的代码（仅在您没有共享模型时使用示例1中的路由数据），并且它按预期工作，即视图中的ActionLink与\u Layout.cshtml中的ActionLink相同。您是否尝试过使用示例2中相同的路线数据来排除这种情况？@Stefan不，我不需要，因为我的路线是定制的，可以在显示url中显示标题。我需要将title、pg和id传递给控制器，但title将在url路由中，pg、id将作为参数，因此看起来像：域/产品类别/title？id=1&pg=1@mjwills不，我没有，也不知道这是否有帮助。请举个例子，谢谢
