Windows8 String 和 Buffer之间的转化

将String转成IBuffer

String^ pwd = "sdfwfsdfwe"; 

InMemoryRandomAccessStream^ memoryStream = ref new InMemoryRandomAccessStream();

 DataWriter^ dataWriter = ref new DataWriter(memoryStream);

 dataWriter->WriteString(pwd);

 IBuffer^ buffer = dataWriter->DetachBuffer();

将Buffer转成String

 DataReader^ dataReader = DataReader::FromBuffer(buffer); 

 String^ fileContent = dataReader->ReadString(buffer->Length);
