此方法用於將指定的Decimal的值轉換為等效的8位無符號整數。
用法: public static byte ToByte (decimal a);
參數:
a:此參數指定要取反的小數。
返回值:將返回一個與a相等的8位無符號整數。
異常:如果值即a小於MinValue或大於MaxValue,則此方法將給出OverflowException。
以下示例程序旨在說明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);
}
}
}
輸出:
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);
}
}
}
輸出:
The Byte value is : 0

// 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);
}
}
}
輸出:
Exception Thrown: System.OverflowException
