c# - 'Class' is a 'type' but is used like a 'variable' -

i'm coding application uses fingerprint reader capture images of someone's fingerprints , save in database.

i'm busy converting vb logic c#, i'm stuck here...

within main form have 2 classes: fingerprints , fingerimage respectively.

my issue following:

from fingerprints class, needed reference fingerimage class. here's code clarity:

this method derived fingerprint class, references fingerimage class:

public byte[] getimagefromfinger(string finger)         {             foreach (fingerimage fi in fingerimage)             {                 if (fi.finger == finger)                     return fi.image;             }             return null;         } 

my problem error can't seem fix...fingerimage 'type' used 'variable'.

i need loop through class 10 times, once each finger, i'm doing wrong , think it's small. appreciated.

furthermore, here's code fingerimage class, in case...

public class fingerimage : frmfingerprintsmain         {             private byte[] _image;             private string _finger;              public fingerimage(byte[] image, string finger)             {                 image = image;                 finger = finger;             }              public byte[] image             {                 { return _image; }                 set { _image = value; }             }              public string finger             {                 { return _finger; }                 set { _finger = value; }             }         } 

you getting error because have no variable named fingerimage. have type called fingerimage.

you need collection of fingerimages somewhere iterate through.
