+# MagyarNemzetiBank.BankAccount
+This library written in pure C# checks the validity of a Hungarian bank account number and determines which bank is belongs to.
+
+## Usage
+Let's check a valid bank account:
+
+```csharp
+string validAccountNumber = "10032000-01076349";
+var accountValid = new BankAccount(validAccountNumber);
+System.Console.WriteLine($"{accountValid.AccountNumber}: IsValid = {accountValid.IsValid}, Bank = {accountValid.Bank}");
+```
+
+An invalid bank account will return `IsValid = false` and throws `FormatException` when `Bank` property is read:
+
+```csharp
+var accountInvalidNumber = new BankAccount("00000000-00000000-00000001");
+System.Console.WriteLine($"{accountInvalidNumber.AccountNumber}: IsValid = {accountInvalidNumber.IsValid}");
+try
+{
+    System.Console.WriteLine($"Checking bank details for {accountInvalidNumber.AccountNumber}");
+    System.Console.WriteLine(accountInvalidNumber.Bank);
+}
+catch (FormatException)
+{
+    System.Console.WriteLine($"{typeof(FormatException)} was thrown because account number was not valid");
+}
+```
+
+When the syntax of the bank account number is correct, but it doesn't belong to any known bank `KeyNotFoundException` is thrown:
+
+```csharp
+var accountInvalidBank = new BankAccount("00000000-00000000");
+System.Console.WriteLine($"{accountInvalidBank.AccountNumber}: IsValid = {accountInvalidBank.IsValid} (it's technically valid)");
+try
+{
+    System.Console.WriteLine($"Checking bank details for {accountInvalidBank.AccountNumber}");
+    System.Console.WriteLine(accountInvalidBank.Bank);
+}
+catch (KeyNotFoundException)
+{
+    System.Console.WriteLine($"{typeof(KeyNotFoundException)} was thrown, because the bank account number doesn't belong to any known bank.");
+}
+```
+
+Alternatively you can use the static `BankAccount.Validate(string accountNumber)` method to check if the number is syntactically correct.
