此方法用於將指定的Decimal的值轉換為等效的64位無符號整數。用戶還可以使用Explicit賦值運算符將Decimal值轉換為64位無符號整數。
用法: public static ulong ToUInt64 (decimal d);
此處,d是要轉換的十進製數。
返回值:它返回一個等於指定值即d的64位無符號整數。
異常:如果指定的值為負或大於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.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);
}
}
}
輸出:
The UInt64 value is : 9223372036854775807 The UInt64 value is : 18446744073709551615
示例2:對於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);
}
}
}
輸出:
Exception Thrown: System.OverflowException
