Alphaleonis.Win32.Network.Host.GetShareInfo doesn't work since 2.1.0

[Schoolmonkey]

While the mehtod workes great in 2.0.1, after Upgrade using just 2 params
Host.GetShareInfo Method (String, Boolean),

in 2.1.0 and newer versions I got an Invalid Share Error

System.Net.NetworkInformation.NetworkInformationException (0x80004005): Diese fr

You are 100% sure the share exists?

@Yomodo
I think I am. I've tested it with 3 servers using shares, the explorer can find without any problems.
Does it work in your environment? When I use the "Get-WmiObject Win32_share" command in the powershell the share is found as well. (Tested with a Windows Server 2012 R2)

The shares have been in format "\server\name".

yup i can confirm that...
@Schoolmonkey - as a workaround you could use this method which worked for me.

GetShareInfo(
string host,
string share,
bool continueOnException
)

It would appear that in the GetShareInfo() function overloads with the single string for uncPath, that the uncPath is first processed as:

var unc = GetHostShareFromPath(uncPath);

This function appears to return the host portion (unc[0]) correctly, but the share path portion (unc[1]) returns with a leading backslash. At this point, it would appear that the leading backslash is correct in the return from GetHostShareFromPath() via the code comments / documentation, however, in looking at older versions of this function it looks like it did not return a leading backslash? This may have changed for Fix #132 with commit 2d5a25b ?

I can reproduce this issue and subsequent "fix" fairly easily in something like LinqPad, for example:

Broken call (similar to what is in the code today):
var hostShare = Host.GetHostShareFromPath(path);
Host.GetShareInfo(hostShare[0], hostShare[1], false);

Working call:
var hostShare = Host.GetHostShareFromPath(path);
Host.GetShareInfo(hostShare[0], hostShare?[1].TrimStart("\".ToCharArray()), false);

Anyway, without knowing where to make the appropriate change, and being new to GitHub pull requests, I'm posting a possible solution here.

Hope this helps!
