Returns the product of two BigInteger values.
Assembly: System.Numerics (in System.Numerics.dll)
Parameters

Type:
System.Numerics::BigInteger
The first number to multiply.
- right
-
Type:
System.Numerics::BigInteger
The second number to multiply.
The Multiply method is implemented for languages that do not support operator overloading. Its behavior is identical to multiplication using the multiplication operator. In addition, the Multiply method is a useful substitute for the multiplication operator when instantiating a BigInteger variable by assigning it a product that results from multiplication, as shown in the following example.
If necessary, this method automatically performs implicit conversion of other integral types to BigInteger objects. This is illustrated in the example in the next section, where the Multiply method is passed two Int64 values.
The following example tries to perform multiplication with two long integers. Because the result exceeds the range of a long integer, an OverflowException is thrown, and the Multiply method is called to handle the multiplication. Note that C# requires that you use either the checked keyword (as in this example) or the /checked+ compiler option to make sure an exception is thrown on a numeric overflow.
