将 ReadonlySpan 转换为 int 的最快方法？

我有一个带有字符串的文件"40070"，我读它并将其转换为ReadonlySpan<byte>变量与52, 48, 48, 55, 48里面。这个Span代表数字40070。我怎样才能投射/转换它ReadonlySpan<byte>返回一个 int？

Thanks

ReadOnlySpan<byte> data = stackalloc byte[] { 52, 48, 48, 55, 48 };
// ^^^ or however you're getting your span; that part doesn't matter

if (System.Buffers.Text.Utf8Parser.TryParse(data, out int value, out int bytes))
{
    Console.WriteLine($"Parsed {bytes} bytes into value: {value}");
}
