add ReadOnlySpan<char> as string parameter

[jpbruyere]

First, thank you for this remarkable utility. Do you plan to introduce 'ReadOnlySpan' as string parameter?

[xin9le]

Thank you for your good suggestion! Just to confirm, do you mean you want some overload methods like following?

• bool IsDefined<T>(ReadOnlySpan<char> value)
• T Parse<T>(ReadOnlySpan<char> value)
• bool TryParse<T>(ReadOnlySpan<char> value, out T result)
• bool TryParse<T>(ReadOnlySpan<char> value, bool ignoreCase, out T result)

Absolutely, I guess every living net library will get to this point soon.

I think I would love to implement ReadOnlySpan<char> overloads. However ReadOnlySpan<char>.GetHashCode() throws NotSupportedException, so I have to workaround this problem. I'm not sure I can do it well, but I'll try it.

Have you consider this method:

public int GetHashCode (ReadOnlySpan<char> source, System.Globalization.CompareOptions options);

The following code worked for me (win10, netcore 3.1)

ReadOnlySpan<char> span = test.AsSpan ();
int a = string.GetHashCode (span, StringComparison.CurrentCulture);

@xin9le I would love this feature too! :)

I am motivated to improve, but I have been working extremely hard for the past few years. I apologize for putting the improvement task on the back burner.

Although it has taken a considerable amount of time, we have now addressed this request. We will be releasing the NuGet Package in the near future 🚀

I've just released v2.0.0-preview2. Please take advantage of it.
