Guid.Parse Method

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

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

public static Guid Parse(
	string input


Type: System.String
The GUID to convert.

Return Value

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


input is null.


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.

using System;

public class Example
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
      Guid originalGuid = Guid.NewGuid();
      // Create an array of string representations of the GUID.
      string[] stringGuids = { originalGuid.ToString("B"),
                               originalGuid.ToString("X") };

      // Parse each string representation.
      foreach (var stringGuid in stringGuids) {
         try {     
            Guid newGuid = Guid.Parse(stringGuid);
            outputBlock.Text += String.Format("Converted {0} to a Guid\n", stringGuid);
         catch (ArgumentNullException) {
            outputBlock.Text += "The string to be parsed is null.\n";   
         catch (FormatException) {
            outputBlock.Text += String.Format("Bad format: {0}", stringGuid);
// 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
