定位并编辑IISExpress的applicationhost。配置，在这里找到: C: \用户{username} \ \ IISExpress \ config文件

重命名一个解决方案:

In Solution Explorer, right-click the project, select Rename, and enter a new name. In Solution Explorer, right-click the project and select Properties. On the Application tab, change the "Assembly name" and "Default namespace". In the main cs file (or any other code files), rename the namespace declaration to use the new name. For this right-click the namespace and select Refactor > Rename enter a new name. For example: namespace WindowsFormsApplication1 Change the AssemblyTitle and AssemblyProduct in Properties/AssemblyInfo.cs. [assembly: AssemblyTitle("New Name Here")] [assembly: AssemblyDescription("")] [assembly: AssemblyConfiguration("")] [assembly: AssemblyCompany("")] [assembly: AssemblyProduct("New Name Here")] [assembly: AssemblyCopyright("Copyright © 2013")] [assembly: AssemblyTrademark("")] [assembly: AssemblyCulture("")] Delete bin and obj directories physically. Rename the project physical folder directory. Open the SLN file (within notepad or any editor) and change the path to the project. Clean and Rebuild the project.

如果在遵循建议的解决方案之后，您已经设法重命名了一个新的解决方案(假设从www.oldsite.com重命名为www.newsite.com)，但仍然使用旧的Web站点项目名称，因为您有一个旧的“ASP。Net Web站点”，然后遵循这些额外的步骤(假设从project1到project2)。

安装和旧的Visual Studio 2017 用它打开项目，右键单击项目->添加->新建项目。 选择“已安装-> Visual c# -> Web ->以前版本-> ASP. exe”。NET空网站”并将其命名为“www.newsite.com” 将Visual Studio 2017中的所有文件和文件夹从旧站点移动到新站点，直到旧站点仍然为空。 右键单击“www.oldsite.com”并删除它。

现在您可以保存所有内容，并使用Visual Studio 2022再次打开它。所有这些都是需要的，因为VS2019/VS2020不支持“旧的”ASP。Net网站创建，但只编辑。

The Rename operations in Visual Studio only change the filename, i.e. *.prj for a project, and *.sln for a solution. You will need to rename folders separately using the filesystem, and you will need to remove and re-add the projects since they will have new folder names. However, note that the solution and project files are respectively text and xml files. You could write your own program that parses them and renames both the folder names, filenames, and fixes the project/solution files internally.

删除bin和obj子文件夹以删除不正确的引用，然后使用windows搜索旧名称。

编辑任何代码或xml文件发现和重建，现在应该是好的。

您还可以导出模板，然后从导出的模板创建一个新项目，根据自己的喜好更改名称
