I'm trying to create text file in memory and write it byte[]. How can I do this?
我正在尝试在内存中创建文本文件并写入它byte[]。我怎样才能做到这一点？
public byte[] GetBytes()
{
MemoryStream fs = new MemoryStream();
TextWriter tx = new StreamWriter(fs);
tx.WriteLine("1111");
tx.WriteLine("2222");
tx.WriteLine("3333");
tx.Flush();
fs.Flush();
byte[] bytes = new byte[fs.Length];
fs.Read(bytes,0,fs.Length);
return bytes;
}
But it does not work because of data length

byte[] ObjectToByteArray(Object obj)
{
using (MemoryStream ms = new MemoryStream())
{
BinaryFormatter b = new BinaryFormatter();
b.Serialize(ms, obj);
return ms.ToArray();
}
}

Try the following code:
试试下面的代码：
public byte[] GetBytes()
{
MemoryStream fs = new MemoryStream();
TextWriter tx = new StreamWriter(fs);
tx.WriteLine("1111");
tx.WriteLine("2222");
tx.WriteLine("3333");
tx.Flush();
fs.Flush();
byte[] bytes = fs.ToArray();
return bytes;
}

public byte[] GetBytes()
{
MemoryStream fs = new MemoryStream();
TextWriter tx = new StreamWriter(fs);
tx.WriteLine("1111");
tx.WriteLine("2222");
tx.WriteLine("3333");
tx.Flush();
fs.Flush();
fs.Position = 0;
byte[] bytes = new byte[fs.Length];
fs.Read(bytes, 0, bytes.Length);
return bytes;
}
