[API Proposal]: IPAddress.IsValid #111282
Description
Background and motivation
Cheaper IPAddress.TryParse(span, out _) for when you don't need the result.
API Proposal
namespace System.Net;
public partial class IPAddress
{
public static IPAddress Parse(string ipString);
public static IPAddress Parse(ReadOnlySpan<char> ipSpan);
public static IPAddress Parse(ReadOnlySpan<byte> utf8Text);
public static bool TryParse(string? ipString, out IPAddress? address);
public static bool TryParse(ReadOnlySpan<char> ipSpan, out IPAddress? address);
public static bool TryParse(ReadOnlySpan<byte> utf8Text, out IPAddress? result);
+ public static bool IsValid(ReadOnlySpan<char> ipSpan);
+ public static bool IsValid(ReadOnlySpan<byte> utf8Text);
}API Usage
-if (IPAddress.TryParse(text, out _))
+if (IPAddress.IsValid(text))We have an internal helper TargetHostNameHelper.IsValidAddress that appears to be doing exactly what IPAddress.IsValid would be:
Alternative Designs
- Allow specifying IPv4 or IPv6 only?
