Can a Byte[] Array be written to a file in C#?
提问by Roberto Bonini
I'm trying to write out a Byte[]array representing a complete file to a file.
我正在尝试将Byte[]表示完整文件的数组写出 到文件中。
The original file from the client is sent via TCP and then received by a server. The received stream is read to a byte array and then sent to be processed by this class.
来自客户端的原始文件通过 TCP 发送，然后由服务器接收。接收到的流被读取到一个字节数组，然后发送给这个类进行处理。
This is mainly to ensure that the receiving TCPClientis ready for the next stream and separate the receiving end from the processing end.
这主要是为了确保接收TCPClient为下一个流做好准备，并将接收端与处理端分开。
The FileStreamclass does not take a byte array as an argument or another Stream object ( which does allow you to write bytes to it).
所述FileStream类不采取一个字节数组作为参数或另一个流对象（它允许你写字节到它）。
I'm aiming to get the processing done by a different thread from the original ( the one with the TCPClient).
我的目标是通过与原始线程（带有 TCPClient 的线程）不同的线程来完成处理。
I don't know how to implement this, what should I try?
我不知道如何实现这一点，我应该尝试什么？

Based on the first sentence of the question: "I'm trying to write out a Byte[] array representing a complete fileto a file."
基于问题的第一句话：“我正在尝试将表示完整文件的 Byte[] 数组写入文件。”
The path of least resistance would be:
阻力最小的路径是：
File.WriteAllBytes(string path, byte[] bytes)

Yep, why not?
是的，为什么不呢？
fs.Write(myByteArray, 0, myByteArray.Length);

You can use a BinaryWriterobject.
您可以使用一个BinaryWriter对象。
protected bool SaveData(string FileName, byte[] Data)
{
BinaryWriter Writer = null;
string Name = @"C:\temp\yourfile.name";
try
{
// Create a new stream to write to the file
Writer = new BinaryWriter(File.OpenWrite(Name));
// Writer raw data
Writer.Write(Data);
Writer.Flush();
Writer.Close();
}
catch
{
//...
return false;
}
return true;
}
Edit:Oops, forgot the finallypart... lets say it is left as an exercise for the reader ;-)
编辑：哎呀，忘了这finally部分……让我们说它留给读者作为练习;-)

You can do this using System.IO.BinaryWriterwhich takes a Stream so:
您可以使用System.IO.BinaryWriterwhich 接受 Stream来执行此操作：
var bw = new BinaryWriter(File.Open("path",FileMode.OpenOrCreate);
bw.Write(byteArray);

There is a static method System.IO.File.WriteAllBytes
有一个静态方法 System.IO.File.WriteAllBytes

You can use the FileStream.Write(byte[] array, int offset, int count)method to write it out.
您可以使用FileStream.Write(byte[] array, int offset, int count)方法将其写出。
If your array name is "myArray" the code would be.
如果您的数组名称为“myArray”，则代码为。
myStream.Write(myArray, 0, myArray.count);

Try BinaryReader:
试试 BinaryReader：
/// <summary>
/// Convert the Binary AnyFile to Byte[] format
/// </summary>
/// <param name="image"></param>
/// <returns></returns>
public static byte[] ConvertANYFileToBytes(HttpPostedFileBase image)
{
byte[] imageBytes = null;
BinaryReader reader = new BinaryReader(image.InputStream);
imageBytes = reader.ReadBytes((int)image.ContentLength);
return imageBytes;
}
