Ethereum Wallet File Parser in C#
As you have discovered, reading the content of Wallet files. Fortunately, we can use the existing Python code to create a C
solution that achieves similar functionality.
In this article, we will explore how to read theWallet content. Batting in C#, focusing on adding, eliminating and exporting keyboards from your wallet file.
Premise
Before you sink into the solution, make sure you have the following premises:
- Software Ethereum Wallet: Install compatible Ethereum (eg Electrum, MyTotherwallet) software to interact with
Wallet.dat.
- .Net Framework 4.x or later: C
is accepted in .net framework 4.x and subsequent versions.
- C
and .Net Development Kit (Dotnet Core)
Data format of the Ethereum wallet
The format of the Wallet.
1
- Accounts
- The history of transactions
We will focus on reading the section of accounts, which contains information about all the addresses registered.
C
solution
Below is a Sample C
solution that demonstrates how to read and handle the files "Wallet.dat:
`Csharp
the use of the system;
using System.io;
Ethereumwalletfileparser name space
{
The public class Walletdareareer
{
Private String _Filepath;
Public Walletdaretareer (String Filepath)
{
_filepath = filepath;
}
public void readwalletata ()
{
Using (Var Filestream = New Filestream (_Filepath, filemode.open))
{
lime contabuffer = byte new [1024];
int bytesread;
// Read the headquarters of the account section
VAR ACCOUNETERADEROFFSET = BITCONVERTER.TOUINT32 (FileStream.Posis, 0);
While ((bytesread = filestream.read (contabuffer, 0, 1024))> 0)
{
IF (bitconverter.islittlendian)
{
// convert bytes into little-endian format
Bitconverter.reverse (buffer);
}
Var Contnumber = Bitconverter.Touint32 (ContBuffer, 0);
VAR contlabel = bitconverter.Touint16 (ContuFFER, 2);
Console.writeline ($ “account {contnumber}: {contlabel}”);
}
}
}

{

While ((bytesread = filestream.read (Contddatuffer, 0, 1024))> 0)
{
IF (bitconverter.islittlendian)
{
// convert bytes into little-endian format
Bitconverter.reverse (buffer);
}
