Guid.TryParse Method
Converts the string representation of a GUID to the equivalent Guid value.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
'Declaration Public Shared Function TryParse ( _ input As String, _ <OutAttribute> ByRef result As Guid _ ) As Boolean
Parameters
- input
- Type: System.String
The GUID to convert.
- result
- Type: System.Guid%
The structure that will contain the parsed value.
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 TryParse 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. Dim newGuid As Guid For Each stringGuid In stringGuids If Guid.TryParse(stringGuid, newGuid) Then outputBlock.Text += String.Format("Converted {0} to a Guid", stringGuid) + vbCrLf Else outputBlock.Text += String.Format("Unable to convert {0} to a Guid", stringGuid) + vbCrLf End If 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
