How can i search in map and get the results back in CCombo.

//Your predefined map values.
HashSet<string> stringSet = new HashSet<string> { "abc", "aa" };

//Copy to new array for operations.
string[] stringList = new string[stringSet.Count];
stringSet.CopyTo(stringList);

//Suppose you type "a" in combo box edit.
string strValue = "a";

//Look for all the values that contains "a"
string[] matchedStrings = Array.FindAll(stringList, delegate(string p)
{
    return (p.Contains(strValue));
}

//Sort array for correct sequence in combo box.
Array.Sort(matchedStrings);

//You should access predefined combox here.
//ComboBox cmbValues = new ComboBox();

//Clear all items from combo box.
cmbValues.Items.Clear();

//Fill the combo box with selected values.
cmbValues.Items.AddRange(matchedStrings);

//default selection to 0th value.
cmbValues.SelectedIndex = 0;
});

Knock out 't' from can't, you can if you think you can.

HashSet<string> stringSet = new HashSet<string> { "abc", "aa" };

I tried the same ,but stilll the same error

HashSet<string> hashSet = new HashSet<string>();
hashSet.Add("abc");
hashSet.Add("aa");

However, it's unusual to deal with enumerators directly in C# - instead just use a 'foreach' loop, which enumerates for you.
