Is there a way to display all enums as their string value in swagger instead of their int value?

I want to be able to submit POST actions and put enums according to

Answer 1

if anyone is interested i have modified the code to work with

.NET CORE 3 and Swagger V5

    public class SwaggerAddEnumDescriptions : IDocumentFilter
{
    public void Apply(OpenApiDocument swaggerDoc, DocumentFilterContext context)
    {
        // add enum descriptions to result models
        foreach (var property in swaggerDoc.Components.Schemas.Where(x => x.Value?.Enum?.Count > 0))
        {
            IList propertyEnums = property.Value.Enum;
            if (propertyEnums != null && propertyEnums.Count > 0)
            {
                property.Value.Description += DescribeEnum(propertyEnums, property.Key);
            }
        }

        // add enum descriptions to input parameters
        foreach (var pathItem in swaggerDoc.Paths.Values)
        {
            DescribeEnumParameters(pathItem.Operations, swaggerDoc);
        }
    }

    private void DescribeEnumParameters(IDictionary operations, OpenApiDocument swaggerDoc)
    {
        if (operations != null)
        {
            foreach (var oper in operations)
            {
                foreach (var param in oper.Value.Parameters)
                {
                    var paramEnum = swaggerDoc.Components.Schemas.FirstOrDefault(x => x.Key == param.Name);
                    if (paramEnum.Value != null)
                    {
                        param.Description += DescribeEnum(paramEnum.Value.Enum, paramEnum.Key);
                    }
                }
            }
        }
    }

    private Type GetEnumTypeByName(string enumTypeName)
    {
        return AppDomain.CurrentDomain
            .GetAssemblies()
            .SelectMany(x => x.GetTypes())
            .FirstOrDefault(x => x.Name == enumTypeName);
    }

    private string DescribeEnum(IList enums, string proprtyTypeName)
    {
        List enumDescriptions = new List();
        var enumType = GetEnumTypeByName(proprtyTypeName);
        if (enumType == null)
            return null;

        foreach (OpenApiInteger enumOption in enums)
        {
            int enumInt = enumOption.Value;

            enumDescriptions.Add(string.Format("{0} = {1}", enumInt, Enum.GetName(enumType, enumInt)));
        }

        return string.Join(", ", enumDescriptions.ToArray());
    }
}
