Guid.Parse Method
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Converts the string representation of a GUID to the equivalent Guid value.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- input
- Type: System.String
The GUID to convert.
| Exception | Condition |
|---|---|
| ArgumentNullException | input is Nothing. |
| FormatException | input is not in a recognized format. |
Use the TryParse method to catch any unsuccessful parse operations without having to explicitly handle exceptions.
The following example creates a new GUID, converts it to three separate string representations by calling the ToString method with the "B", "D", and "X" format specifiers, and then calls the Parse method to convert the strings back to Guid values.
Module Example Public Sub Demo(outputBlock As System.Windows.Controls.TextBlock) Dim originalGuid As Guid = Guid.NewGuid() ' Create an array of string representations of the GUID. Dim stringGuids() As String = { originalGuid.ToString("B"), originalGuid.ToString("D"), originalGuid.ToString("X") } ' Parse each string representation. For Each stringGuid In stringGuids Try Dim newGuid As Guid = Guid.Parse(stringGuid) outputBlock.Text += String.Format("Converted {0} to a Guid", stringGuid) + vbCrLf Catch e As ArgumentNullException outputBlock.Text += "The string to be parsed is null." + vbCrLf Catch e As FormatException outputBlock.Text += String.Format("Bad format: {0}", stringGuid) + vbCrLf End Try Next End Sub End Module ' The example displays the following output: ' Converted {81a130d2-502f-4cf1-a376-63edeb000e9f} to a Guid ' Converted 81a130d2-502f-4cf1-a376-63edeb000e9f to a Guid ' Converted {0x81a130d2,0x502f,0x4cf1,{0xa3,0x76,0x63,0xed,0xeb,0x00,0x0e,0x9f}} to a Guid
