I'm new to C#.

I know in vb.net, i can do this:

Dim guid as string = System.Guid.NewGuid.ToString

In C#, I'm trying to do 

String guid = System.Guid.NewGuid().ToString;

but i get an "Cannot convert method group 'ToString' to non-delegate type 'string'. Did you intend to invoke the method?" error.

Here are examples of output from each of the format specifiers:

N: cd26ccf675d64521884f1693c62ed303
D: cd26ccf6-75d6-4521-884f-1693c62ed303
B: {cd26ccf6-75d6-4521-884f-1693c62ed303}
P: (cd26ccf6-75d6-4521-884f-1693c62ed303)
X: {0xcd26ccf6,0x75d6,0x4521,{0x88,0x4f,0x16,0x93,0xc6,0x2e,0xd3,0x03}}

The default is D.

Run this yourself.

Guid guidId = Guid.Parse("xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx");
string guidValue = guidId.ToString("D"); //return with hyphens

Following Sonar rules, you should whenever you can try to protect yourself, and use System.globalisation whenever it's possible like for DateTime.ToString().

So regarding the other answers you could use: 

guid.ToString("", CultureInfo.InvariantCulture)

where "" can be replaces by : N, D, B , P and X for more infos see this comment.
