How to replace more than one claims?

[cqkisyouq]

public Response SetClaimsOnContext(List<ClaimToThing> claimsToThings, HttpContext context)
{
     foreach (var config in claimsToThings)
     {
                var value = _claimsParser.GetValue(xxxxxx);
                if (value.IsError)
                {
                    return new ErrorResponse(value.Errors);
                }
                var exists = context.User.Claims.FirstOrDefault(x => x.Type == config.ExistingKey);
                var identity = context.User.Identity as ClaimsIdentity;
                if (exists != null)
                {
                    identity?.RemoveClaim(exists);
                }
                identity?.AddClaim(new System.Security.Claims.Claim(config.ExistingKey, value.Data));
     }
     return new OkResponse();
}

I'm only given one value here, but I have multiple values.I'm only going to replace the first configuration value here, delete it when I find it, add my value to it, how do I replace more than one?

I hope so -> Claims[role]=1,Claims[role]=2,Claims[role]=3
to Claims[scope]=1,Claims[scope]=2,Claims[scope]=3
