Swashbuckle 和 Swagger 库无法识别“信息”类

Question

我是否缺少包或参考，因为我的AddSwaggerGen方法无法编译。 我的代码：

我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：

错误 CS0246 找不到类型或命名空间名称“Info”（您是否缺少 using 指令或程序集引用？）这是 csproj

Answer 1

版本 5 中已弃用Info

它已被OpenApiInfo取代，因此您必须在您的招摇设置中反映这一点：

c.SwaggerDoc("v1", new OpenApiInfo { Version = "1.0", Title = "My API" });

Answer 2

将 Info 类更改为 OpenApiInfo 类。

使用 Microsoft.OpenApi.Models 添加
