ZString.Join is slower than String.Join about zstring HOT 4 CLOSED

solution.

In a generic method, branch when T is a string.

Change the sb.Append(values[i]); to the following.

if (typeof(T) == typeof(string))
{
    sb.Append(Unsafe.As<string>(values[i]));
}
else
{
    sb.Append(values[i]);
}

The benchmark results are detailed below.

System.Join seems to be optimized for arrays.

In #18, it was always faster than in version 2.1.2 when using string as a type argument.

However, String.Join is faster in some cases.

⚠ indicates that allocation will occur.
