Examples

The following code example encodes a string into an array of bytes, and then decodes the bytes back into a string.

using namespace System;
using namespace System::Text;
int main()
{
   
   // Create an instance of UTF7Encoding.
   UTF7Encoding^ u7 = gcnew UTF7Encoding( true );
   
   // Create byte arrays from the same string containing the following characters:
   //    Latin Small Letter Z (U+007A)
   //    Latin Small Letter A (U+0061)
   //    Combining Breve (U+0306)
   //    Latin Small Letter AE With Acute (U+01FD)
   //    Greek Small Letter Beta (U+03B2)
   String^ myStr = "za\u0306\u01FD\u03B2";
   
   // Encode the string.
   array<Byte>^myBArr = gcnew array<Byte>(u7->GetByteCount( myStr ));
   u7->GetBytes( myStr, 0, myStr->Length, myBArr, 0 );
   
   // Decode the byte array.
   Console::WriteLine( "The new string is: {0}", u7->GetString( myBArr, 0, myBArr->Length ) );
}

/*

The new string is: za??

Remarks

Data to be converted, such as data read from a stream, might be available only in sequential blocks. In this case, or if the amount of data is so large that it needs to be divided into smaller blocks, the application should use the Decoder or the Encoder provided by the GetDecoder method or the GetEncoder method, respectively.
