法律研究在 C# 中的数组中使用 foreach 循环
让我们看一个在数组中使用 foreach 循环的例子 −
示例
using System;
public class Demo {
public static void Main() {
string[] products = new string[] { "Electronics", "Accessories", "Clothing", "Toys", "Clothing", "Furniture" };
Console.WriteLine("Products list...");
foreach(string s in products) {
Console.WriteLine(s);
}
Console.WriteLine("Is the products Accessories in the array? = {0}", Array.Exists(products, ele => ele == "Accessories"));
Console.WriteLine("Is the products Stationery in the array? = {0}", Array.Exists(products, ele => ele == "Stationery"));
Console.WriteLine("
One or more products begin with the letter 'C'? = {0}", Array.Exists(products, ele => ele.StartsWith("C")));
Console.WriteLine("One or more planets begin with 'D'? = {0}", Array.Exists(products, ele => ele.StartsWith("D")));
Console.WriteLine("One or more products begin with the letter 'T'? = {0}", Array.Exists(products, ele => ele.StartsWith("T")));
Console.WriteLine("One or more planets begin with 'E'? = {0}", Array.Exists(products, ele => ele.StartsWith("E")));
Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize);
}
}输出
将会产生以下输出 −
Products list... Electronics Accessories Clothing Toys Clothing Furniture Is the products Accessories in the array? = True Is the products Stationery in the array? = False One or more products begin with the letter 'C'? = True One or more planets begin with 'D'? = False One or more products begin with the letter 'T'? = True One or more planets begin with 'E'? = True Is the array having fixed size? = True
示例
我们来看看另一个例子 −
using System;
public class Demo {
public static void Main() {
String[] strArr1 = new String[3] { "John", "Jacob", "Tim"};
String[] strArr2 = new String[3] { "Tom","Brad","Bradley"};
Console.WriteLine("First String array...");
foreach(string val in strArr1) {
Console.WriteLine(val);
}
Console.WriteLine("Second String array...");
foreach(string val in strArr2) {
Console.WriteLine(val);
}
Console.WriteLine("Are both the array objects equal? = "+strArr1.Equals(strArr2));
}
}输出
将会产生以下输出 −
First String array... John Jacob Tim Second String array... Tom Brad Bradley Are both the array objects equal? = False
