E语言中字节集·对应C#代码

后弦

In E language, a "byteset" is a data type that represents a set of bytes, similar to an array of bytes in C#. Here is how you might declare and use a byteset in E language:

byteset bs;
bs = "Hello, world!";
bs[0] = 'H'; // Set the first byte of the byteset to 'H'
bs[5] = ','; // Set the sixth byte of the byteset to ','
print(bs); // Prints "Hello, world!"

To achieve a similar effect in C#, you can use a byte array:


byte[] bs = Encoding.UTF8.GetBytes("Hello, world!");bs[0] = (byte)'H'; // Set the first byte of the array to 'H'bs[5] = (byte)','; // Set the sixth byte of the array to ','Console.WriteLine(Encoding.UTF8.GetString(bs)); // Prints "Hello, world!"


You can also use a MemoryStream object to manipulate a sequence of bytes as a stream in C#:


using (MemoryStream stream = new MemoryStream())
{
    stream.WriteByte((byte)'H'); // Write the byte 'H' to the stream
    stream.WriteByte((byte)','); // Write the byte ',' to the stream
    stream.Write(Encoding.UTF8.GetBytes("ello, world!"), 0, 12); // Write the remaining bytes to the stream
    stream.Position = 0; // Reset the position of the stream to the beginning
    Console.WriteLine(new StreamReader(stream).ReadToEnd()); // Prints "Hello, world!"
}


Keep in mind that the specific syntax and behavior of bytesets in E language may vary depending on the implementation you are using. Make sure to consult the documentation for your specific E language implementation for more information.

直接(Array)object.Cast(byte).ToArray(); 就能直接传字节集

(obj as Array).Cast<byte>().ToArray();
