获取在C#中迭代StringCollection的枚举数
要获得遍历StringCollection的枚举数，代码如下-
示例
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
StringCollection stringCol = new StringCollection();
String[] arr = new String[] { "100", "200", "300", "400", "500" };
Console.WriteLine("Array elements...");
foreach (string res in arr){
Console.WriteLine(res);
}
stringCol.AddRange(arr);
Console.WriteLine("Does the specified string is in the StringCollection? = "+stringCol.Contains("800"));
Console.WriteLine("Total number of elements = "+stringCol.Count);
Console.WriteLine("Iterating through StringCollection = "+stringCol.Count);
StringEnumerator myenum = stringCol.GetEnumerator();
while (myenum.MoveNext())
Console.WriteLine(myenum.Current);
}
}输出结果
这将产生以下输出-
Array elements... 100 200 300 400 500 Does the specified string is in the StringCollection? = False Total number of elements = 5 Iterating through StringCollection = 5 100 200 300 400 500
示例
让我们看另一个例子-
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
StringCollection stringCol = new StringCollection();
stringCol.Add("10");
stringCol.Add("20");
stringCol.Add("30");
stringCol.Add("40");
stringCol.Add("50");
stringCol.Add("60");
stringCol.Add("70");
stringCol.Add("80");
stringCol.Add("90");
stringCol.Add("100");
Console.WriteLine("Elements...");
foreach (string res in stringCol){
Console.WriteLine(res);
}
Console.WriteLine("Iterating through StringCollection with Enumerator...");
StringEnumerator myenum = stringCol.GetEnumerator();
while (myenum.MoveNext())
Console.WriteLine(myenum.Current);
}
}输出结果
这将产生以下输出-
Elements... 10 20 30 40 50 60 70 80 90 100 Iterating through StringCollection with Enumerator... 10 20 30 40 50 60 70 80 90 100
