Convert string value back to GUID value

Question

hi,

i have a guid value that i store in my hidden variable. say for eg (303427ca-2a5c-df11-a391-005056b73dd7)

now how do i convert the value from this hidden field back to GUID value (because the method i would be calling expects a GUID value).

thank you.

Answer 1

    string strGuid;
    strGuid = (your guid here);
    Guid guid = new Guid(strGuid);

Answer 2

Guid has a constructor for string Guids.

Guid guid = new Guid(myStringGuid);

Answer 3

new Guid(myHiddenFieldString)

Answer 4

Just use the overloaded constructor:

try
{
  Guid guid = new Guid("{D843D80B-F77D-4655-8A3E-684CC35B26CB}");
}
catch (Exception ex) // There might be a more appropriate exception to catch
{
  // Do something here in case the parsing fails.
}

Answer 5

I think it can be done simply as following:

Guid MyGuid = new Guid(stringValue);

Answer 6

You are making it pretty easy on an attacker by storing the Guid in a string. Trivial to find back in, say, the paging file. Store it in a Guid and kill two birds with one stone.
