检查指定类型是否为值类型的 C# 程序
原文:https://www . geesforgeks . org/c-sharp-program-to-check-a-specified-type-is-a-value-type-or-not/
在 C# 中,值类型表示一个位序列。它不是类或接口,它被称为结构或枚举(值类型的特例)。因此,为了检查指定的类型是否是值类型,我们使用类型类的 is Value Type 属性。它是只读属性。如果类型是值类型,它将返回真。否则,它将返回 false。它将为枚举返回真,但不会为枚举类型返回真。
语法:
public bool IsValueType { get; }
例 1:
C
// C# program to check whether the specified
// type is a value type or not
using System;
using System.Reflection;
// Declare a structure
struct myStructure
{
// Declaring a method
public static void display()
{
Console.WriteLine("Hello! GeeksforGeeks");
}
}
// Declare a class
public class Geeks
{
// Declaring a method
public static void show()
{
Console.WriteLine("Hey! GeeksforGeeks");
}
}
public class GFG{
// Driver class
public static void Main(string[] args)
{
// Checking the given type is a value type or not
// Using IsValueType Property
Console.WriteLine(typeof(myStructure).IsValueType);
Console.WriteLine(typeof(Geeks).IsValueType);
}
}
输出:
True
False
例 2:
C
// C# program to check whether the specified
// type is a value type or not
using System;
using System.Reflection;
// Declare a structure
struct myGFG
{
// Declaring a method
public static void display()
{
Console.WriteLine("Welcome to GeeksforGeeks");
}
}
public class GFG{
// Driver class
public static void Main(string[] args)
{
// Checking the given type is a value type or not
// Using IsValueType Property
if (typeof(myGFG).IsValueType == true)
{
Console.WriteLine("The given type is value type");
}
else
{
Console.WriteLine("The given type is not a value type");
}
}
}
输出:
The given type is value type
