Finding a particular field from ArrayList of struct

[bbg9507]

Hi, question about using ArrayList from C# newbie,

I managed to make my array list which holds a number of structs:

struct myStruct
{
public int field1;
public int field2;
}

static ArrayList myArray = new ArrayList();

How could I find a struct that holds a particular value in field1?
IndexOf()?

I wrote a method like:

int findStruct(ArrayList arr)
{
  int idx = -1;
  for (int i = 0; i < arr.Count; i++)
    if (((myStruct)arr[i]).id == 0x0302)
      {
      idx = i;
      break;
      }
 
       return idx;
}

Any other fancy way to do a job?

You could use the IndexOf() method of the ArrayList:

myStruct struct = new MyStruct();
struct.Field1 = 1; //or whatever int you're searching for
struct.Field2 = 2; //ditto
 
int foundIndex = myArrayList.IndexOf(struct);

int foundIndex = myArrayList.IndexOf(struct);
 

Thanks for reply RoninZA,

I guess IndexOf() can be used as you suggested when I know all field values.
What if I know just one of the field and don't care other fields?

Best way would be to loop through the structure and try and find the index you are looking for.
