Guid.Parse Method

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

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
public static Guid Parse(
	string input
)

Parameters

input
Type: System.String

The GUID to convert.

Return Value

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

input is null.

FormatException

input is not in a recognized format.

Use TryParse method to catch any unsuccessful parse operations.

The following example creates a new GUID, converts it to three separate string representations by calling the ToString(String) 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 Main()
   {
      Guid originalGuid = Guid.NewGuid();
      // Create an array of string representations of the GUID. 
      string[] stringGuids = { originalGuid.ToString("B"),
                               originalGuid.ToString("D"),
                               originalGuid.ToString("X") };

      // Parse each string representation. 
      foreach (var stringGuid in stringGuids) {
         try {     
            Guid newGuid = Guid.Parse(stringGuid);
            Console.WriteLine("Converted {0} to a Guid", stringGuid);
         }   
         catch (ArgumentNullException) {
            Console.WriteLine("The string to be parsed is null.");   
         }                                   
         catch (FormatException) {
            Console.WriteLine("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
