Question

I have a code like this

int rpindex = allObjects.Find(new Guid(policyGuid));

if (rpindex != -1)
{
    rp = (ResourcePolicy)allObjects.GetAt(rpindex);
}

and this is Find method

public virtual int Find(Guid guid) 
{
    try 
    {
       for (int i=0; i<this.Count; i++)
       {
           if (guid.Equals(this[i].Guid))
          {
             return i;
          }
       }
    }
    catch(System.Exception exception)
    {
       SpoDebug.DebugTraceSevere(func, "Exception Occurred: " + exception.ToString() );
    }

    SpoDebug.DebugTraceVerbose(func, "no find. guid=" + guid.ToString());
    return -1;
}

As of now the existing function Find() outcome is -1 or some integer value[i]. The -1 value will come in two situations , that is if the input is empty [ null value] and if the input is some value which is not in the database or in the current list, i need change here.That mean if the input to Find() is empty or null that time only it should return -1, otherwise if input has some value and it is not maching then it shud return return -2.SO there should be three outcomes one is -1 second is -2 and third is integer value ,Can any body guide me here
if i add else loop, i am not sure what return value i can use here other than -1, and integer value

Answer 1

just after the for loop check

if(i == this.Count) //i reached the end of the loop but no matches found
{
 return -2;
}
