in solidity how to convert msg.data to address?

Hello, can nethereum use abi to parse the input data like web3. For example, the input data is the transfer method, but I don’t know in advance that it is the transfer method. After the analysis, the program parses and tells me that this is the transfer method. And tell me the corresponding parameters

@juanfranblanco

Does anyone know?

I am trying to implement log crawling to my program

processor.ExecuteAsync(
                        toBlockNumber: toBlockNum,
                        cancellationToken: cancellationToken,
                        startAtBlockNumberIfNotProcessed: blocknum
                        );

toBlockNum is current block and blocknum is last crawled block

EthDepositedEventLogs.count() is always 0 even though etherscan is showing an event was dispatched

http://playground.nethereum.com/csharp/id/1032

I followed this tutorial exactly except the log processing is in a while loop

thank you for any help

@heddhshan

hi, @juanfranblanco , recommend add "evaluate or test" method, such as "erc20 token function transfer", add a c# method “test_TransferRequestAsync”, and "test_TransferRequestAsync" return bool.

return bool and error msg

@heddhshan that is mainly making a function call as opposed to a transfer

but it could be added to the template

@GoodGalaxyGeeks post your code in discord i can have a quick look

@GoodGalaxyGeeks

@juanfranblanco I attached My Code picture as I said i have long wait on SendRequestwaitforRecieptAsync and it never add to Etherscan.io , if its need Mining for add Transaction Block Please Guid me and give Sample Code

Hi, does anyone know if my WebSocketClient hit an error, how can i restart it. for example i want my client to reconnect if internet disconnected or anything happens to the network.

` client.Error += (sender, e) => Client_Error(sender, e, blockHeaderSubscription);
await client.StartAsync();
await blockHeaderSubscription.SubscribeAsync();

   private static void Client_Error(object sender, Exception ex,
        EthNewBlockHeadersObservableSubscription blockHeaderSubscription)
    {
    // how can i reconnect client here?!
}    `

Is there an easy way to get the function selectors for contract functions? I'm playing with a contract that expects some function selectors, but didn't know if I had to manually construct that myself or if Nethereum gives a way to get those

Hi, I am testing out AWS Ethereum Preview but I am getting the following error:

Error occurred when trying to send rpc requests(s)

I am able to access the EthExplorerURL and I can see it is running.

Here is the code I am using (I randomly replaced some values in the url, etc):

@juanfranblanco hi, I was curious if there is a way to specify aws credentials with nethereum? I am running AWS Ethereum and have a client that I can connect to my node using web3.js using my aws credentials but not sure how I would connect using nethereum?
