示例
下面的代码示例演示如何使用 BinaryReader 类顶部的 MemoryStream 和 类将数据读取和BinaryWriter写入Double内存。
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;
try

// Read and verify the data.
i = 0;
Console::WriteLine( "Verifying the written data." );
