I try to get balance in address.
It is my code:
`using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Nethereum.Web3;
using System.Threading.Tasks;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
Bananas().Wait();
}
static private async Task Bananas()
{
var publicKey = "0xC0b4ec83028307053Fbe8d00ba4372384fe4b52B";
var web3 = new Nethereum.Web3.Web3("https://ropsten.infura.io/myInfura");
//var txCount = await web3.Eth.Transactions.GetTransactionCount.SendRequestAsync(publicKey);
var balance = await web3.Eth.GetBalance.SendRequestAsync(publicKey);
var etherAmount = Web3.Convert.FromWei(balance.Value);
Console.WriteLine(web3);
Console.WriteLine("Get txCount ", etherAmount);
Console.ReadLine();
}
}
}`
I installed Nethereum via PM console: Nethereum.
I use a normal link of infura.
Why don`t I get a next result without the balance in address?
I have just made a console application with your code and all the data is coming back fine from Nethereum.
Your issue is with your Console.WriteLine(... You are passing the etherAmount as a arg0 property into the Console.WriteLine which will not output correctly on the console when you run it.
Try this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Nethereum.Web3;
using System.Threading.Tasks;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
Bananas().Wait();
}
static private async Task Bananas()
{
var publicKey = "0xC0b4ec83028307053Fbe8d00ba4372384fe4b52B";
var web3 = new Nethereum.Web3.Web3("https://ropsten.infura.io/myInfura");
//var txCount = await web3.Eth.Transactions.GetTransactionCount.SendRequestAsync(publicKey);
var balance = await web3.Eth.GetBalance.SendRequestAsync(publicKey);
var etherAmount = Web3.Convert.FromWei(balance.Value);
Console.WriteLine(web3);
Console.WriteLine("Get txCount " + etherAmount);
Console.ReadLine();
}
}
}
ps nice 1110.337873197299357846 ETH ;) (i know it is only test ETH but we can dream)

Can we have some example to get list of all files from all folder from Azure Data Lake using .NET(C#).

How to list all virtual directories and subdirectories
using System;
using System.Net;
static class Program {
public static void Main()
{
WebClient wc = new WebClient();
var proxies = wc.DownloadString(#"http://proxy-ip-list.com/download/free-proxy-list.txt");
Console.WriteLine("http://" + proxies.Split(';')[5]);
Console.ReadLine();
}
}
I'm very much baffled...
I tried printer Char-by-Char.
I tried assigning the string to a variable before writing.
I've tried everything, what's going on?
Console.WriteLine("http://" + "182.255.46.123:8080"); works...
It's because the string being returned contains a carriage-return character at the beginning:
proxies.Split(';')[5] = " \r182.255.46.123:8080"
You can remove it like this:
Console.WriteLine("http://" + proxies.Split(';')[5].Replace("\r", "").Trim());
Try this:
using System;
using System.Text.RegularExpressions;
using System.Net;
namespace Rextester
{
public class Program
{
public static void Main(string[] args)
{
WebClient wc = new WebClient();
var proxies = wc.DownloadString(#"http://proxy-ip-list.com/download/free-proxy-list.txt");
var regex = new Regex(#"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:\d{1,5}");
var match = regex.Matches(proxies);
Console.WriteLine("http://" + match[3].Value);
Console.ReadLine();
}
}
}
Is most save in case of changes in content of the request result.
Updated answer as per your comment. You just need to Trim() to remove all white spaces from start and end.
using System;
using System.Net;
static class Program
{
public static void Main()
{
WebClient wc = new WebClient();
var proxies = wc.DownloadString(#"http://proxy-ip-list.com/download/free-proxy-list.txt");
Console.WriteLine("http://" + proxies.Split(';')[5].Trim());
Console.ReadLine();
}
}

I'm messing around with the System.Net library in C# and I'm trying to simply have it set up such that you enter an url and it will take that as a string and put that into the parameter for the URl in the Client.DownloadString() field.
Here is my code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
namespace StringDownloadTest
{
class GetInformation
{
string EnterString;
public string InputString()
{
EnterString = Console.ReadLine();
return EnterString;
}
}
class DownloadString
{
static void Main(string[] args)
{
GetInformation R = new GetInformation();
R.InputString();
string downloadedString;
System.Net.WebClient client;
client = new System.Net.WebClient();
downloadedString = client.DownloadString(R.InputString());
Console.WriteLine("String: {0}", downloadedString);
}
}
}
Any help here, it will compile but the program crashes.
You're calling R.InputString twice and only entering input for the first time.
Try:
GetInformation R = new GetInformation();
Console.WriteLine("Please enter a valid url protocol://domain");
var input = R.InputString();
Uri uri;
if(!Uri.TryCreate(input, UriKind.Absolute, out uri))
{
Console.WriteLine("Url format could not be determined for {0}", input);
Environment.Exit(1);
}
var client = new System.Net.WebClient();
var downloadedString = client.DownloadString(uri);
Console.WriteLine("String: {0}", downloadedString);

I would follow the directions here, on the Mongo site. Windows quickstart is a really good resource to get started using Mongo on windows.
As far as connecting to the Mongo instance in .Net, if you didn't do anything special during the installation of Mongo, you shouldn't have to explicitly give a connection string. The following code works for my generic set up of Mongo.
