BigInteger Explicit Conversion (BigInteger to Byte)

Defines an explicit conversion of a BigInteger object to an unsigned byte value.

Namespace:  System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)

public static explicit operator byte (
	BigInteger value


Type: System.Numerics.BigInteger
The value to convert to a Byte.

Return Value

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


value is less than Byte.MinValue.


value is greater than Byte.MaxValue.

The overloads of the Explicit(Decimal to BigInteger) method define the types to which or from which a BigInteger 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 CByte 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 Byte data type. There is no loss of precision in the resulting Byte value if the conversion is successful.

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