C# Decimal.ToUInt64()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64位无符号整数。用户还可以使用Explicit赋值运算符将Decimal值转换为64位无符号整数。

用法: public static ulong ToUInt64 (decimal d);

此处,d是要转换的十进制数。


返回值:它返回一个等于指定值即d的64位无符号整数。

异常:如果指定的值为负或大于MaxValue,则此方法将给出OverflowException。

以下示例程序旨在说明上述方法的用法:

示例1:

// C# program to demonstrate the 
// Decimal.ToUInt64(Decimal) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Taking decimal variables 
            Decimal dec1 = 9223372036854775807.999m; 
            Decimal dec2 = 18446744073709551615.784m; 
  
            // using Decimal.ToUInt64(Decimal) Method 
            ulong val1 = Decimal.ToUInt64(dec1); 
  
            // using Decimal.ToUInt64(Decimal) Method 
            ulong val2 = Decimal.ToUInt64(dec2); 
  
            // Printing the UInt64 value 
            Console.WriteLine("The UInt64 value "
                             + "is : {0}", val1); 
                                
  
            // Printing the UInt64 value 
            Console.WriteLine("The UInt64 value "
                             + "is : {0}", val2); 
                                
        } 
  
        catch (OverflowException e) { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
The UInt64 value is : 9223372036854775807
The UInt64 value is : 18446744073709551615

示例2:对于OverflowException

// C# program to demonstrate the 
// Decimal.ToUInt64(Decimal) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Taking the maximum value 
            // of Decimal 
            Decimal dec1 = Decimal.MaxValue; 
  
            // using Decimal.ToUInt64(Decimal) Method 
            // It will give error as decimal number 
            // is above the range of UInt64 
            ulong val1 = Decimal.ToUInt64(dec1); 
  
            // Printing the UInt64 value 
            Console.WriteLine("The UInt64 value "
                               + "is : {0}",val1);                            
        } 
  
        catch (OverflowException e) { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
Exception Thrown: System.OverflowException
