c EnumHelper enumeration common operation classes

The test code is as follows:

namespace CutPictureTest.Comm
{

  public class EnumHelper
  {

    public static System.Collections.ArrayList GetName(Type enumType)
    {
      System.Collections.ArrayList arr = new System.Collections.ArrayList();
      string[] n = System.Enum.GetNames(enumType);
      foreach (string item in n)
        arr.Add(item);
      return arr;

    }

    public static T ToEnum<T>(string strEnum)
    {
      T t = (T)Enum.Parse(typeof(T), strEnum);
      return t;
    }

    public static System.Collections.Hashtable EnumToHashtable(Type enumType)
    {
      System.Collections.Hashtable ht = new System.Collections.Hashtable();
      Array arr = System.Enum.GetValues(enumType);
      for (int i = 0; i < arr.Length; i++)
        ht.Add(Convert.ToInt16(arr.GetValue(i)), arr.GetValue(i).ToString());
      return ht;
    }
  }
}

Call mode:

System.Collections.Hashtable arr = Comm.EnumHelper.EnumToHashtable(typeof(tImageFormat));
      foreach (string item in arr.Values)
        cb.Items.Add(item);

Where cb stands for ComboBox object, you can replace it with your drop-down object.
