Guid.TryParse Method
Visual Studio 2010
Updated: August 2011
Converts the string representation of a GUID to the equivalent Guid structure.
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 Main() 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 Console.WriteLine("Converted {0} to a Guid", stringGuid) Else Console.WriteLine("Unable to convert {0} to a Guid", stringGuid) 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
