Is there a way change the Controller's name in the swagger-ui page?

Question

I\'m using Swashbuckle to enable the use of swagger and swagger-ui in my WebApi project.

In the following image you can see two of my controllers shown in the swagger-ui

I tried using venerik's answer, but it still kept the original controller name in the UI along with the new tag that you specify. I also didn't like that you had to add an attribute to every function, so I came up with a solution where you only have to add an attribute to the controller. There are two steps:

Add DisplayNameAttribute on the controller:

[DisplayName("Your New Tag")]
public class YourController : ApiController
{
    // ...
}

Then in the Swagger configuration, you can override the base functionality using the GroupActionsBy function to pull the name that you specified in that attribute:

GlobalConfiguration.Configuration
    .EnableSwagger(c => {

        c.GroupActionsBy(apiDesc => {
            var attr = apiDesc
                .GetControllerAndActionAttributes()
                .FirstOrDefault();

            // use controller name if the attribute isn't specified
            return attr?.DisplayName ?? apiDesc.ControllerName(); 
        });

    })
    .EnableSwaggerUi(c => {
        // your UI config here
    });

ControllerName() is an extension method defined in the Swagger-Net library. If you aren't using that you can also get the controller name from apiDesc.ActionDescriptor.ControllerDescriptor.ControllerName
