XdrSCVal in stellar_dotnet_sdk

[xsoul]

Hi, I'm trying to write SorobanClient in C#, by reference to what Soroban PHP sdk have, here is the php function in their getTransactionResponse class

public function getResultValue(): ?XdrSCVal {
        if ($this->error != null || $this->status != self::STATUS_SUCCESS || $this->resultMetaXdr == null) {
            return null;
        }

        $meta = XdrTransactionMeta::fromBase64Xdr($this->resultMetaXdr);
        $results = $meta->v3?->txResult->result->results;
        if ($results == null || count($results) == 0) {
            return null;
        }
        $successArr = $results[0]->getResultTr()?->getInvokeHostFunctionResult()?->success;
        if($successArr != null) {
            return $successArr[0];
        }

I would like to convert it to become my c# method, however, for the xdrScVal, what should I use in stellar_dotnet_sdk as replacement?

Also, how should i convert the getInvokeHostFunctionResult? here is what i have, i'm stucked...

public string GetResultValue()
        {
            if(this.Error != null || this.Result == null || this.Result.Status != STATUS_SUCCESS || this.Result.ResultMetaXdr == null)
            {
                return null;
            }
            byte[] bytes = Convert.FromBase64String(this.Result.ResultMetaXdr);
            stellar_dotnet_sdk.xdr.TransactionResult result = stellar_dotnet_sdk.xdr.TransactionResult.Decode(new XdrDataInputStream(bytes));

            var resultRes = stellar_dotnet_sdk.responses.TransactionResult.FromXdr(result);
            if (resultRes == null || resultRes.IsSuccess == false) return null;

            if(result.Result == null || result.Result.Results.Count() == 0) return null;
            result.Result.Results[0].Tr.????
        }

Thanks
