Sample c# code on transferring mosaic

Technical Discussion
#1

Hello everyone. We were able to get address status using csharp2nem project. We are having a hard time sending mosaic from one address to another. Please help. Thanks

#2

What issue are you having? (sorry, i only just saw this)

#3

We are having problem sending mosaic…we find a sample c# code in cshart2nem but when we tried, it did not update the balance of the mosaic. (https://github.com/NemProject/csharp2nem/blob/master/NemApi/Wrapper/RequestClients/TransactionClient.cs) can you lead me to sample code in c# that can transfer mosaic. thanks.

This is the sample code we did.

// To get mosaic information of the account from the address.
var mosaicClient = new NamespaceMosaicClient(connection);
var mosaicResult = mosaicClient.BeginGetMosaicsOwned(Address);
var mosaicResponse = mosaicClient.EndGetMosaicsOwned(mosaicResult);

            foreach(var data in mosaicResponse.Data)
            {
                // XEM is mosaic, but it does not shown because it has already been shown on the above.
                if (data.MosaicId.Name != "xem")
                {
                    Mosaics.Add(new Mosaic
                    {
                        Name = data.MosaicId.Name,
                        Amount = data.Quantity.ToString("N6")

                    });
                    MosaicList.Add(new CSharp2nem.Model.Transfer.Mosaics.Mosaic(data.MosaicId.NamespaceId,data.MosaicId.Name,240000));
                    
                    Debug.WriteLine(data.MosaicId.NamespaceId);
                }
            }

            //transfer transaction
            var accountFactory = new PrivateKeyAccountClientFactory(connection);
            var accClient = accountFactory.FromPrivateKey("7921112a8aea456fad3b260b97fa61aa77a9df362dfacec2e748ae8977ea5d7d");
           
            
            var transData = new TransferTransactionData()
                {
                    Message = " ",
                    RecipientAddress = "TDRQ6B5K6434DU3QURHZP4PSIIN4LOP7G5O4T73G", 
                    ListOfMosaics = MosaicList
                };

            var transResult = accClient.BeginSendTransaction(transData);
            var response = accClient.EndTransaction(transResult);
        }
        catch(Exception ex)
        {

        }

i dont see anything wrong at first look. Perhaps try using Fiddler (https://www.telerik.com/download/fiddler) to see if the Http request is actually going through, and if so, if any errors are picked up.

if it helps, you can try adapting your code to the following:

class TestClass
{
    static void Main() 
    {         
        Connection connection = new Connection();
             
        connection.SetTestnet();
             
        var accountFactory = new PrivateKeyAccountClientFactory(connection);
     
        PrivateKeyAccountClient accClient = accountFactory.FromPrivateKey("<key>");
           
        var mosaicsList = new List<Mosaic>()
        {
            new Mosaic("<namespaceName>", "<mosaicName>", 100000)
        };
             
        var transData = new TransferTransactionData()
        {
            Amount = 1000000, // amount should always be 1000000 micro xem when attaching mosaics as it acts as a multiplier.
            Message = "message here if needed",
            RecipientAddress = "<address>", 
            ListOfMosaics = mosaicsList
        };
             
        try
        {
            accClient.BeginSendTransaction(body =>
            {
                try
                {
                    if (body.Ex != null) throw body.Ex;
     
                    Console.WriteLine("message: " + body.Content.Message);                                                                                                                                                  
                }
                catch (Exception e)
                {
                    Console.WriteLine("error: " + e.Message);
                }
            }, transData);
        }
        catch (Exception ex)
        {              
            Console.WriteLine("error: " + ex.Message);
        }
    }                                                       
}

this just worked for me bar the mosaic not being known.
