i have a doubt can i use an account created in metamask using nethereum? i tried this.

var abi = @"";
var addressContract = "";
var myAddress = "xxxxx";
var password = "password";
var managedAccount = new ManagedAccount(myAddress, password);

var web3ManagedAccount = new Web3(managedAccount);
var contract = web3ManagedAccount.Eth.GetContract(abi, addressContract);

var method= contract.GetFunction("method");

SendTransactionAndWaitForReceiptAsync(from: myAddress, new HexBigInteger(3000), value: null, null, abcBytes, newAddress);

but return an error that say:The method personal_sendTransaction does not exist/is not available

Update

I had a big mistake, i needed to pass the private key and not the password, thanks for your help

var abi = @"";
var addressContract = "0xA0XXXXX";
var myPriveteKey= "myKey";
var managedAccount = new ManagedAccount(myPriveteKey);

  • you need to check version of web3. – Mahesh Rajput Oct 11 '19 at 8:10

This is generally causing because of two problems :

  1. mismatch version of your web3
  2. forgot to unlock the account the send transactions.

So, try to change the version of web3 and try again or you need to unlock account that you are going to use for send transactions.
