将文件转换为二进制C＃

Question

I want to convert file into binary. I tried, but I get 0X000000000000000..... It is not correct. Always every file getting that digits. Please help me to solve thanks in advance

if (value.resume_file.CompareTo("") != 0)
{
    byte[] binary = new byte[value.resume_file.Length];
    //binary =  Convert.ToByte(value.resume_file);
    objJobSeekers.IsResume = true;
    objJobSeekers.DocFileName = value.resume_file;
    objJobSeekers.Resume = binary;
    objJobSeekers.TypedResume = DBNull.Value;
}

Answer 1

string to byte[]

byte[] bytes = System.Text.Encoding.UTF8.GetBytes(str);

byte[] to string

str = System.Text.Encoding.UTF8.GetString(bytes);

Is this what you looking for?

Answer 2

If you want to read any file from disk and get its bytes then use

string FileDir = "D:\\File.doc";
byte[] MyBytes = File.ReadAllBytes(FileDir);

If you want to convert some random object in memory into bytes then you can use a BinarySerializer

byte[] MyBytes;
BinaryFormatter bf = new BinaryFormatter();
using (MemoryStream ms = new MemoryStream())
{
    bf.Serialize(ms, obj);
    MyBytes = ms.ToArray();
}
