For Asp .Net MVC 5 you can use.
Following the need to be done in Swagger Config file.

private class AddAuthorizationHeaderParameter: IOperationFilter   // as a nested class in script config file.
{
    public void Apply(Operation operation, SchemaRegistry schemaRegistry, ApiDescription apiDescription)
    {
        if (operation.parameters == null)
            operation.parameters = new List();

        operation.parameters.Add(new Parameter
        {
            name = "Authorization",
            @in = "header",
            type = "string",
            required = true
        });
    }
}

c.OperationFilter(); // finally add this line in .EnableSwagger

You can also add any no of headers for header implementation in Swagger.
