C# Decimal.ToByte()用法及代码示例


此方法用于将指定的Decimal的值转换为等效的8位无符号整数。

用法: public static byte ToByte (decimal a);

参数:
a:此参数指定要取反的小数。


返回值:将返回一个与a相等的8位无符号整数。

异常:如果值即a小于MinValue或大于MaxValue,则此方法将给出OverflowException。

以下示例程序旨在说明Decimal.ToByte(Decimal)方法的用法:

示例1:

// C# program to demonstrate the 
// Decimal.ToByte(Decimal) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring the decimal variable 
            Decimal a = 127.97m; 
  
            // using ToByte() method; 
            byte value = Decimal.ToByte(a); 
  
            // Display the byte value 
            Console.WriteLine("The Byte value "+ 
                             "is : {0}", value); 
        } 
  
        catch (OverflowException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
The Byte value is : 127

示例2:

// C# program to demonstrate the 
// Decimal.ToByte(Decimal) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring the decimal variable 
            Decimal a = -0.999m; 
  
            // using ToByte() method; 
            byte value = Decimal.ToByte(a); 
  
            // Display the byte value 
            Console.WriteLine("The Byte value"+ 
                           " is : {0}", value); 
        } 
  
        catch (OverflowException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
The Byte value is : 0

示例3:溢出异常程序

// C# program to demonstrate the 
// Decimal.ToByte(Decimal) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring the decimal variable 
            Decimal a = -98.45m; 
  
            // using ToByte() method; 
            byte value = Decimal.ToByte(a); 
  
            // Display the byte value 
            Console.WriteLine("The Byte value "+ 
                             "is : {0}", value); 
        } 
  
        catch (OverflowException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
Exception Thrown: System.OverflowException
