Convert.ToString Method (Byte, IFormatProvider)

.NET Framework 2.0

Converts the value of the specified 8-bit unsigned integer to its equivalent String representation.

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

public static string ToString (
	byte value,
	IFormatProvider provider
)

public static String ToString (
	byte value, 
	IFormatProvider provider
)

JScript

public static function ToString (
	value : byte, 
	provider : IFormatProvider
) : String

Parameters

value: An 8-bit unsigned integer.

provider: An IFormatProvider interface implementation that supplies culture-specific formatting information.

Return Value

The String equivalent of the value of value.

Remarks

This implementation is identical to Byte.ToString.

Example

The following code example converts an unsigned Byte value to a String with the ToString method, using an IFormatProvider object.

C++

// Example of the Convert.ToString( numeric types ) and 
// Convert.ToString( numeric types, IFormatProvider ) methods.
using System;
using System.Globalization;

        // These properties will affect the conversion.
