c# - Swashbuckle和Swagger库无法识别“Info”类

Question

我是否缺少软件包或引用，因为AddSwaggerGen方法无法编译。我的代码:

我添加了using Swashbuckle.AspNetCore.Swagger;
但是这段代码

  services.AddSwaggerGen(c =>
   {
     c.SwaggerDoc("v1", new Info { Title = "My API", Version = "v1" });                 
     c.EnableAnnotations();    
   });

不会编译:

Error CS0246 The type or namespace name 'Info' could not be found (are you missing a using directive or an assembly reference?) Here is the csproj

<Project Sdk="Microsoft.NET.Sdk.Web">

Info在版本5中已弃用

它已被OpenApiInfo取代，因此您必须在您的 Swagger 设置中反射(reflect)出来:

c.SwaggerDoc("My_Api", new OpenApiInfo { Version = "1.0", Description = "my api " });
