Guid.Parse Method

Converts the string representation of a GUID to the equivalent Guid value.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Public Shared Function Parse ( _
	input As String _
) As Guid


Type: System.String
The GUID to convert.

Return Value

Type: System.Guid
A structure that contains the value that was parsed.


input is Nothing.


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("X") }

      ' Parse each string representation.
      For Each stringGuid In stringGuids
            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     
   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
