[SOLVED] C# namespace name 'Models' does not exist in the namespace 'Moralis'

Technical Issue Reporting
#1

Hi, I’m trying the following tutorial

But I’m receiving an error
" namespace name ‘Models’ does not exist in the namespace ‘Moralis’ (are you missing an assembly reference?)"

I have added the Moralis library to the application

using Moralis;
using Moralis.Web3Api.Models;

namespace ConsoleDemo
{
    internal class Program
    {
        static void Main(string[] args)
        {
            if (args.Length < 2)
            {
                Console.Write("Usage: ConsoleDemo.exe ADDRESS CLIENT_ID");
                return;
            }

            string address = "########";
            ChainList chainId = ChainList.eth;

            // Setup Moralis Client
            **MoralisClient.ConnectionData = new Moralis.Models.ServerConnectionData()**
            {
                ApiKey = "#####"
            };

            Task.Run(async () =>
            {
                await DisplayCryptoData(address, chainId);
            }).Wait();

        }

        internal static async Task DisplayCryptoData(string address, ChainList chainId)
        {
            try
            {
                Console.WriteLine($"For address: {address}...\n");

                // Load native balance for address
                NativeBalance bal = await MoralisClient.Web3Api.Account.GetNativeBalance(address, chainId);

                double nativeBal = 0;

                double.TryParse(bal.Balance, out nativeBal);

                Console.WriteLine($"Your native balance is {bal.NativeTokenBalance}");

                // Load ERC20 Token List for address
                List<Erc20TokenBalance> erc20Balnaces = await MoralisClient.Web3Api.Account.GetTokenBalances(address, chainId);

                Console.WriteLine("\n\nYour ERC 20 Tokens:");

                if (erc20Balnaces != null && erc20Balnaces.Count > 0)
                {
                    // Print out each token with symbol and balance.
                    foreach (Erc20TokenBalance tb in erc20Balnaces)
                    {
                        Console.WriteLine($"\t{tb.Symbol} - {tb.Name}: {tb.NativeTokenBalance}");
                    }
                }
                else
                {
                    Console.WriteLine("\tNone");
                }

                // Load first 10 NFTs for the address
                NftOwnerCollection nfts = await MoralisClient.Web3Api.Account.GetNFTs(address, (ChainList)chainId, "", null, 10);

                Console.WriteLine("\n\nYour NFTs:");

                if (nfts != null && nfts.Result.Count > 0)
                {
                    // Print out each token with symbol and balance.
                    foreach (NftOwner nft in nfts.Result)
                    {
                        Console.WriteLine($"\t{nft.Name}: {nft.Amount}\n\tMetaData: {nft.Metadata}\n\n");
                    }
                }
                else
                {
                    Console.WriteLine("\tNone");
                }

            }
            catch (Exception ex)
            {
                Console.Error.WriteLine(ex);
            }
        }
    }
}

it looks like the error could be from here

here is imported as Moralis.Web3Api.Models

I don’t know how it should be used or if it should work as it is

#3

Yes that’s where it’s breaking, it doesn’t seem to have ConnectionData or Models definition within the MoralisClient interface

// Setup Moralis Client
MoralisClient.ConnectionData = new Moralis.Models.ServerConnectionData()
{
ApiKey = “”
};

Hi, I’m still waiting on a reply to my ticket/issue.

Thanks,

Hey @brucey54,

Can we know which version of the C# SDK are you using at the moment? :raised_hands:

So we can assist accordingly, thanks!

#6

Hi YosephKS, I’m using C# SDK Moralis 1.0.4.6

That’s the latest version.

Thanks,
Tom

Hey @brucey54,

If your version is 1.0.4.6, it might not suit the tutorial that you have in here :raised_hands:

As you see that this tutorial is for C# SDK version 2.x.x

The namespace error might come from here. Let me know if you have any other questions
