Decimal.ToInt64 Method (Decimal)
Converts the value of the specified Decimal to the equivalent 64-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
The return value is the integral part of the decimal value; fractional digits are truncated.
You can also convert a Decimal value to a 64-bit integer by using the Explicit(Decimal to Int64) assignment operator. Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
