foreach (string res in strCol) {
Console.WriteLine(res);
}
Console.WriteLine("Index of first occurrence of Books? = "+strCol.IndexOf("Books"));
}
} আউটপুট
এটি নিম্নলিখিত আউটপুট −

এখন আরেকটি উদাহরণ দেখা যাক -
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
StringCollection strCol = new StringCollection();
String[] strArr = new String[] { "A", "B", "C", "D", "E", "F", "D", "H" };
Console.WriteLine("StringCollection elements...");
foreach (string str in strArr) {
Console.WriteLine(str);
}
strCol.AddRange(strArr);
Console.WriteLine("Element at 5th index = "+strCol[5]);
Console.WriteLine("Count of strings in StringCollection = " + strCol.Count);
Console.WriteLine("Index of first occurrence of D? = "+strCol.IndexOf("D"));
}
} আউটপুট
এটি নিম্নলিখিত আউটপুট −
তৈরি করবেStringCollection elements... A B C D E F D H Element at 5th index = F Count of strings in StringCollection = 8 Index of first occurrence of D? = 3
