Decimal.ToUInt64() Method in C#
Last Updated :
17 Feb, 2019
This method is used to convert the value of the specified Decimal to the equivalent 64-bit unsigned integer. A user can also convert a Decimal value to a 64-bit unsigned integer by using the Explicit assignment operator.
Syntax: public static ulong ToUInt64 (decimal d);
Here, the d is the decimal number which is to be converted.
Return Value: It returns a 64-bit unsigned integer equivalent to the specified value i.e. d.
Exception: This method will give OverflowException if the specified value is negative or greater than MaxValue.
Below programs illustrate the use of the above-discussed method:
Example 1:
using System;
class GFG {
public static void Main()
{
try {
Decimal dec1 = 9223372036854775807.999m;
Decimal dec2 = 18446744073709551615.784m;
ulong val1 = Decimal.ToUInt64(dec1);
ulong val2 = Decimal.ToUInt64(dec2);
Console.WriteLine( "The UInt64 value "
+ "is : {0}" , val1);
Console.WriteLine( "The UInt64 value "
+ "is : {0}" , val2);
}
catch (OverflowException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
}

Output:
The UInt64 value is : 9223372036854775807
The UInt64 value is : 18446744073709551615
Example 2: For OverflowException
using System;
class GFG {
public static void Main()
{
try {
Decimal dec1 = Decimal.MaxValue;
ulong val1 = Decimal.ToUInt64(dec1);
Console.WriteLine( "The UInt64 value "
+ "is : {0}" ,val1);
}
catch (OverflowException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
}
|
Output:
Exception Thrown: System.OverflowException
