检查指定的字符串是否在 StringCollection 中，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("数组元素...");
foreach (string res in arr) {
Console.WriteLine(res);
}
stringCol.AddRange(arr);
Console.WriteLine("Does the specified string is in the StringCollection? = "+stringCol.Contains("800"));
}
}
输出
这将产生以下输出 −
Array elements... 100 200 300 400 500 Does the specified string is in the StringCollection? = False
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();
String[] arr = new String[] { "John", "Tim", "Kevin", "Bradman", "Katie", "Tom", "Nathan" };
Console.WriteLine("String 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("Katie"));
}
}
输出
这将产生以下输出 −
String array elements... John Tim Kevin Bradman Katie Tom Nathan Does the specified string is in the StringCollection? = True
