Examples
The following code example shows how to read and write Double data to memory by using the BinaryReader and BinaryWriter classes on top of the MemoryStream class.
using namespace System;
using namespace System::IO;
int main()
{
int i;
const int arrayLength = 1000;
// Create random data to write to the stream.
array<double>^dataArray = gcnew array<double>(arrayLength);
Random^ randomGenerator = gcnew Random;
for ( i = 0; i < arrayLength; i++ )
{
dataArray[ i ] = 100.1 * randomGenerator->NextDouble();
}
BinaryWriter^ binWriter = gcnew BinaryWriter( gcnew MemoryStream );
try
{
// Write data to the stream.
Console::WriteLine( "Writing data to the stream." );
i = 0;
for ( i = 0; i < arrayLength; i++ )
{
binWriter->Write( dataArray[ i ] );
}
// Create a reader using the stream from the writer.
BinaryReader^ binReader = gcnew BinaryReader( binWriter->BaseStream );
// Return to the beginning of the stream.
binReader->BaseStream->Position = 0;

// Read and verify the data.
i = 0;

Obsolete.
Initializes a new instance of the EndOfStreamException class with the specified serialization and context information. |
| EndOfStreamException(String) |
Initializes a new instance of the EndOfStreamException class with its message string set to |
| EndOfStreamException(String, Exception) |
