已解决！好的

秘方是：

a、 ）使用MapToApiVersion-Swagger属性装饰控制器的操作方法。。。例如：

[MapToApiVersion（“1.0”）]

b、 ）确保DocInclusionPredite lambda的设置如下：

setup.DocInclusionPredicate((version, desc) => 
                {
                    if (!desc.TryGetMethodInfo(out MethodInfo methodInfo))
                        return false;

                    var versions = methodInfo.DeclaringType
                    .GetCustomAttributes(true)
                    .OfType<ApiVersionAttribute>()
                    .SelectMany(attr => attr.Versions);

                    var maps = methodInfo
                    .GetCustomAttributes(true)
                    .OfType<MapToApiVersionAttribute>()
                    .SelectMany(attr => attr.Versions)
                    .ToArray();

                    return versions.Any(v => $"v{v.ToString()}" == version)
                    && (!maps.Any() || maps.Any(v => $"v{v.ToString()}" == version));
                });

setup.DocInclusionPredicate（（版本，描述）=>
{
如果（！desc.TryGetMethodInfo（out MethodInfo MethodInfo））
返回false；
var versions=methodInfo.DeclaringType
.GetCustomAttributes（true）
        // NOTE: declaration order matters for versioning APIs to be setup correctly
        services.AddVersionedApiExplorer(o => // this is required to support swagger gathering info on all of the existing endpoints for ALL versions of APIs
        {
             o.GroupNameFormat = "'v'VVV";
             o.SubstituteApiVersionInUrl = true;
        });

        services.AddApiVersioning(o =>
        {
            o.ReportApiVersions = true;
            o.AssumeDefaultVersionWhenUnspecified = true;
            o.DefaultApiVersion = new ApiVersion(1, 0);
        });

        #region Swashbuckle Overview - an automated Swagger content generator -- See: https://github.com/domaindrivendev/Swashbuckle.WebApi
        //  Seamlessly adds a Swagger to WebApi projects! Combines ApiExplorer and Swagger/ swagger - ui to provide a rich discovery, documentation and playground experience
        //  to your API consumers.
        //  In addition to its Swagger generator, Swashbuckle also contains an embedded version of swagger - ui which it will automatically serve up once Swashbuckle is installed.
        //  This means you can complement your API with a slick discovery UI to assist consumers with their integration efforts.Best of all, it requires minimal coding and maintenance,
        //  allowing you to focus on building an awesome API!
        //  And that's not all ...
        //  Once you have a Web API that can describe itself in Swagger, you've opened the treasure chest of Swagger-based tools including a client generator that can be targeted to a wide
        //  range of popular platforms. See swagger-codegen for more details.
        //
        //  Features:
        //  Auto-generated Swagger 2.0
        //    * Seamless integration of swagger-ui
        //    * Reflection - based Schema generation for describing API types
        //    * Extensibility hooks for customizing the generated Swagger doc
        //    * Extensibility hooks for customizing the swagger - ui
        //    * Out - of - the - box support for leveraging Xml comments
        //    * Support for describing ApiKey, Basic Auth and OAuth2 schemes... including UI support for the Implicit OAuth2 flow
        //
        //  How does Swashbuckle find the endpoints that it needs to document?...
        //      Swashbuckle requires the use of routing attributes to find the endpoints... if you are using conventional routing (as opposed to attribute routing), any controllers and the actions
        //      on those controllers that use conventional routing will not be represented in ApiExplorer, which means Swashbuckle won't be able to find those controllers
        //      and generate Swagger operations from them.  For example:
        //
        //          [Route("example")]
        //          public class ExampleController : Controller
        //
        //  IMPORTANT: Ensure your API actions and parameters are decorated with explicit "Http" and "From" bindings.
        //      [HttpPost]
        //      public void CreateProduct([FromBody] Product product)
        //      ...
        //      [HttpGet]
        //      public IEnumerable<Product> SearchProducts([FromQuery] string keywords)

        //      NOTE: If you omit the explicit parameter bindings, the generator will describe them as "query" params by default.
        //      TIP: to correctly setup versioning in conjunction with Swagger, see: https://stackoverflow.com/questions/60084877/swagger-not-finding-apiversion-ed-actions
