检查数组在C#中是否为只读
要检查数组是否为只读，请尝试以下代码-
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);
Console.WriteLine("Is the array read only? = " + products.IsReadOnly);
}
}输出结果
这将产生以下代码-
One or more planets begin with 'E'? = False Is the array having fixed size? = True Is the array read only? = False
示例
让我们看另一个例子-
using System;
public class Demo {
public static void Main(){
string[] products = { "Mobiles", "Laptop", "Watches", "Books" };
Console.WriteLine("Products list...");
foreach(string s in products){
Console.WriteLine(s);
}
Console.WriteLine("\nOne 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 read only? = " + products.IsReadOnly);
}
}输出结果
这将产生以下代码-
Products list... Mobiles Laptop Watches Books One or more products begin with the letter 'C'? = False One or more planets begin with 'D'? = False One or more products begin with the letter 'T'? = False One or more planets begin with 'E'? = False Is the array read only? = False
