BigInteger Explicit Conversion (BigInteger to SByte)

Defines an explicit conversion of a BigInteger object to a signed 8-bit value.

This API is not CLS-compliant.

	BigInteger value


Type: System.Numerics.BigInteger
The value to convert to a signed 8-bit value.

Return Value

Type: System.SByte
An object that contains the value of the value parameter.


value is less than SByte.MinValue.


value is greater than SByte.MaxValue.

The overloads of the Explicit(Decimal to BigInteger) method define the types to which or from which a BigInteger object can be converted. Language compilers do not perform this conversion automatically because it can involve data loss. Instead, they perform the conversion only if a casting operator (in C#) or a conversion function (such as CType or CSByte in Visual Basic) is used. Otherwise, they display a compiler error.

Because this operation defines a narrowing conversion, it can throw an OverflowException at run time if the BigInteger value is outside the range of the SByte data type. There is no loss of precision in the resulting SByte value if the conversion is successful.

The following example illustrates the conversion of BigInteger values to SByte values. It also handles an OverflowException that is thrown because the BigInteger value is outside the range of the SByte data type.
