What's the best way to verify an address is correct in C#?

Question

Is there an easy way to validate an Ethereum address in C#?

Basically, I am looking for the method that correspond to these ones in Javascript but in C#.

Answer 1

In C#, you can use this method from the Nethereum NuGet package:

/// <summary>
/// Validates if the hex string is 40 alphanumeric characters
/// </summary>
public bool IsValidEthereumAddressHexFormat(string address)
{
    if (string.IsNullOrEmpty(address)) return false;
    return address.HasHexPrefix() && IsValidAddressLength(address) &&
           address.IsHex();
}
