C#中的Array.FindAll()方法
C#中的Array.FindAll()方法用于检索与指定谓词定义的条件匹配的所有元素。
语法
以下是语法-
public static T[] FindAll<T> (T[] array, Predicate<T> match);
示例
现在让我们看一个实现Array.FindAll()方法的示例-
using System;
public class Demo{
public static void Main(){
Console.WriteLine("Array elements...");
string[] arr = { "car", "bike", "truck", "bus"};
for (int i = 0; i < arr.Length; i++){
Console.Write("{0} ", arr[i]);
}
Console.WriteLine();
String[] res = Array.FindAll(arr, ele => ele.StartsWith("b",
StringComparison.Ordinal));
Console.Write("\nAll Searched elements...\n");
for (int i = 0; i < res.Length; i++) {
Console.WriteLine("{0}", res[i]);
}
Console.WriteLine();
}
}输出结果
这将产生以下输出-
Array elements... car bike truck bus All Searched elements... bike bus
