法律研究检查 C# 中的数组是否有固定大小
尝试以下代码以检查数组是否有固定的大小 −
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
这将产生以下输出 −
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
让我们看另一个示例 −
using System;
public class Demo {
public static void Main(){
string[] products = new string[] { };
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
这将产生以下输出 −
One or more planets begin with 'E'? = False Is the array having fixed size? = True
