Encoding::Convert Method (Encoding^, Encoding^, array<Byte>^)


Converts an entire byte array from one encoding to another.

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

static array<unsigned char>^ Convert(
	Encoding^ srcEncoding,
	Encoding^ dstEncoding,
	array<unsigned char>^ bytes


Type: System.Text::Encoding^

The encoding format of bytes.

Type: System.Text::Encoding^

The target encoding format.

Type: array<System::Byte>^

The bytes to convert.

Return Value

Type: array<System::Byte>^

An array of type Byte containing the results of converting bytes from srcEncoding to dstEncoding.

Exception Condition

srcEncoding is null.


dstEncoding is null.


bytes is null.


A fallback occurred (see Character Encoding in the .NET Framework for complete explanation)


srcEncoding.DecoderFallback is set to DecoderExceptionFallback.


A fallback occurred (see Character Encoding in the .NET Framework for complete explanation)


dstEncoding.EncoderFallback is set to EncoderExceptionFallback.

The following example converts a Unicode-encoded string to an ASCII-encoded string. Because the ASCII encoding object returned by the ASCII property uses replacement fallback and the Pi character is not part of the ASCII character set, the Pi character is replaced with a question mark, as the output from the example shows.

using namespace System;
using namespace System::Text;

int main()
   String^ unicodeString = "This string contains the unicode character Pi (\u03a0)";

   // Create two different encodings.
   Encoding^ ascii = Encoding::ASCII;
   Encoding^ unicode = Encoding::Unicode;

   // Convert the string into a byte array.
   array<Byte>^unicodeBytes = unicode->GetBytes( unicodeString );

   // Perform the conversion from one encoding to the other.
   array<Byte>^asciiBytes = Encoding::Convert( unicode, ascii, unicodeBytes );

   // Convert the new Byte into[] a char and[] then into a string.
   array<Char>^asciiChars = gcnew array<Char>(ascii->GetCharCount( asciiBytes, 0, asciiBytes->Length ));
   ascii->GetChars( asciiBytes, 0, asciiBytes->Length, asciiChars, 0 );
   String^ asciiString = gcnew String( asciiChars );

   // Display the strings created before and after the conversion.
   Console::WriteLine( "Original String*: {0}", unicodeString );
   Console::WriteLine( "Ascii converted String*: {0}", asciiString );
// The example displays the following output:
//    Original string: This string contains the unicode character Pi (Π)
//    Ascii converted string: This string contains the unicode character Pi (?)
