Creating a Guid -> conversion from VB to C#

Question

I have the following code in VB.Net and I'm trying to convert it to C#.

 listContacts = ACT_FRAMEWORK.Contacts.GetContactsByID(Nothing, New Guid() {New Guid(ContactID)})

Below is my attempt so far:

 Guid[] test = new Guid[1];
 test[0] = Guid.NewGuid(ContactID);   
 contactList = actApp.Contacts.GetContactsByID(null, test);

The abover errors because NewGuid() takes no arguments. I have also tried.

test[0] = contactID1;

However, you can't convert from string to Guid. Can anyone help with this?

Isn't there a [`Guid.Parse`](https://msdn.microsoft.com/en-us/library/system.guid.parse(v=vs.110).aspx) you could use? — Manfred Radlwimmer, Feb 13 '18 at 11:44
It doesn't throw an error so that could be what I'm looking for. — benjiiiii, Feb 13 '18 at 11:45

Guid.NewGuid is a method, and you're not calling that method from your VB code - you're calling the constructor accepting a string. You can call that same constructor in C#:

// Using an array initializer for simplicity
Guid[] test = { new Guid(ContactID) };

Or if you want to make the call in one line as per your VB code:

contactList = actApp.Contacts.GetContactsByID(null, new[] { new Guid(ContactID) });

I think it's a shame that NewGuid has that name rather than CreateGuid, but such is life :(

Using Guid.Parse will work too of course - judging by the .NET Core source code they behave extremely similarly; the constructor just handles overflow exceptions slightly differently.

I could have sworn I tried this! Must have made an error when attempting it. Thanks! — benjiiiii, Feb 13 '18 at 11:45

Try Guid.Parse(ContactID.ToString());

if ContactID is actually a string , simple write Guid.Parse(ContactID);
