C# Decimal.ToSByte()用法及代碼示例

此方法用於將指定的Decimal的值轉換為等效的8位有符號整數。用戶還可以使用Explicit賦值運算符將Decimal值轉換為8位整數。

用法： public static sbyte ToSByte (decimal value);

在此，該值是要轉換的十進製數。

返回值：它返回一個等於指定值的8位有符號整數。

異常：如果指定的值小於MinValue或大於MaxValue，則此方法將給出OverflowException。

以下示例程序旨在說明上述方法的用法：

示例1:

// C# program to demonstrate the 
// Decimal.ToSByte() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Taking decimal variables 
            Decimal dec1 = 127.5555M; 
            Decimal dec2 = 04.2996m; 
  
            // using Decimal.ToSByte(Decimal) Method 
            sbyte val1 = Decimal.ToSByte(dec1); 
  
            // using Decimal.ToSByte(Decimal) Method 
            sbyte val2 = Decimal.ToSByte(dec2); 
  
            // Printing the SByte value 
            Console.WriteLine("The SByte value "
                             + "is : {0}", val1); 
                                
  
            // Printing the SByte value 
            Console.WriteLine("The SByte value "
                             + "is : {0}",val2); 
                                
        } 
  
        catch (OverflowException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

The SByte value is : 127
The SByte value is : 4

示例2:

// C# program to demonstrate the 
// Decimal.ToSByte() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // taking a decimal number 
            // above the range of SByte 
            Decimal dec1 = 129M; 
  
            // Taking the maximum value 
            // of Decimal 
            Decimal dec2 = Decimal.MaxValue; 
  
            // using Decimal.ToSByte(Decimal) Method 
            // It will give error as decimal number 
            // is above the range of SByte 
            sbyte val1 = Decimal.ToSByte(dec1); 
  
            // using Decimal.SByte(Decimal) Method 
            // It will give error as Decimal.MaxValue 
            // value is out of range from SByte 
            int val2 = Decimal.ToSByte(dec2); 
  
            // Printing the SByte value 
            Console.WriteLine("The SByte value "
                              + "is : {0}",val1); 
                                
  
            // Printing the SByte value 
            Console.WriteLine("The SByte value "
                           + "is : {0}",  val2); 
                              
        } 
  
        catch (OverflowException e) 
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

Exception Thrown: System.OverflowException
