Decimal.ToInt64() Method in C#
Last Updated :
30 Jan, 2019
This method is used to convert the value of the specified Decimal to the equivalent 64-bit signed integer. A user can also convert a Decimal value to a 64-bit integer by using the Explicit assignment operator.
Syntax: public static long ToInt64 (decimal d);
Here, the value is the decimal number which is to be converted.
Return Value: It returns a 64-bit signed integer equivalent to the specified value.
Exception: This method will give OverflowException if the specified value is less than MinValue 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 = -926534668654775808.859m;
Decimal dec2 = 4897498545.2364654M;
long val1 = Decimal.ToInt64(dec1);
long val2 = Decimal.ToInt64(dec2);
Console.WriteLine( "The Int64 value "
+ "is : {0}" , val1);
Console.WriteLine( "The Int64 value "
+ "is : {0}" , val2);
}
catch (OverflowException e)
{
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
}
|
Output:
The Int64 value is : -926534668654775808
The Int64 value is : 4897498545
Example 2: For OverflowException
using System;
class GFG {
public static void Main()
{
try {
Decimal dec1 = Decimal.MinValue;
Decimal dec2 = Decimal.MaxValue;
long val1 = Decimal.ToInt64(dec1);
long val2 = Decimal.ToInt64(dec2);
Console.WriteLine( "The Int64 value "
+ "is : {0}" , val1);
Console.WriteLine( "The Int64 value "
+ "is : {0}" , val2);
}
catch (OverflowException e)
{
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
}

Output:
Exception Thrown: System.OverflowException
