Guid.NewGuid Method
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Initializes a new instance of the Guid class.
Assembly: mscorlib (in mscorlib.dll)
This is a convenient static method that you can call to get a new Guid.
There is a very low probability that the value of the new Guid is all zeroes or equal to any other Guid. You can determine whether a GUID consists of all zeros by comparing it to Guid.Empty.
The following code example creates and displays the values of two Guid objects.
// This code example demonstrates the Guid.NewGuid() method. using System; class Example { public static void Demo(System.Windows.Controls.TextBlock outputBlock) { Guid g; // Create and display the value of two GUIDs. g = Guid.NewGuid(); outputBlock.Text += g + "\n"; outputBlock.Text += Guid.NewGuid() + "\n"; } } /* This code example produces the following results: 0f8fad5b-d9cb-469f-a165-70867728950e 7c9e6679-7425-40de-944b-e07fc1f90ae7 */
