C＃中的Double.GetTypeCode()方法

Double.GetTypeCode()方法用于返回值类型Double的TypeCode。

Syntax: public TypeCode GetTypeCode ();

Return Value: This method returns the enumerated constant, Double.

下面的程序说明Double.GetTypeCode()方法的用法：

范例1：

// C# program to demonstrate the
// Double.GetTypeCode()
// Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Declaring and initializing value1
        double value1 = 10d;
  
        // getting the typeCode
        // using GetTypeCode() method
        TypeCode value = value1.GetTypeCode();
  
        // Display the TypeCode
        Console.WriteLine("TypeCode is {0}", value);
    }
}

输出：

TypeCode is Double

范例2：

// C# program to demonstrate the
// Double.GetTypeCode()
// Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        // calling get() method
        get(5d);
        get(5.5d);
        get(10d);
        get(7.5d);
    }
  
    // defining get() method
    public static void get(double value1)
    {
  
        // getting the TypeCode
        // using GetTypeCode() method
        TypeCode value = value1.GetTypeCode();
  
        // Display the TypeCode
        Console.WriteLine("TypeCode is {0}", value);
    }
}

输出：

TypeCode is Double
TypeCode is Double
TypeCode is Double
TypeCode is Double
