Cannot convert string to GUID in C#.NET [duplicate]

Question

Why would the cast (to a System.Guid type) statement be invalid (second line in try block)?

For example, suppose I have a string with a value of "5DD52908-34FF-44F8-99B9-0038AFEFDB81". I'd like to convert that to a GUID. Is that not possible?

    Guid ownerIdGuid = Guid.Empty;     try     {         string ownerId = CallContextData.Current.Principal.Identity.UserId.ToString();         ownerIdGuid = (Guid)ownerId;     }     catch     {         // Implement catch     } 

Answer 1

Try this:

Guid ownerIdGuid = Guid.Empty;             try {     string ownerId = CallContextData.Current.Principal.Identity.UserId.ToString();     ownerIdGuid = new Guid(ownerId); } catch {     // implement catch  } 

Answer 2

Try this:

ownerIdGuid = Guid.Parse(ownerId); 

ownerId is a string, you cannot cast it to a Guid directly.
