C＃中的Decimal.ToByte()方法

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。

Syntax: public static byte ToByte (decimal a);

Parameter:
a: This parameter specifies the decimal which will be negated.

Return Value: An 8-bit unsigned integer equivalent to a will be returned.

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

下面的程序说明了Decimal.ToByte(Decimal)方法的用法：

范例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

范例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： OverflowException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
