将一个Stream 和一个二进制流转换成字符串

1.

将一个流转换成字符串

    public partial class WebForm2 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            WebClient wc = new WebClient();
            System.IO.Stream stream = wc.OpenRead("http://localhost:34992/WebForm1.aspx");


            StreamReader reader = new StreamReader(stream);
            string ss = reader.ReadToEnd();  //将一个流文件转换成字符串
            Response.Write(ss);
        }
    }
}

将一个流转换成一个二进制数组

 

private byte[] StreamToByte(Stream stream)
{
    byte[] buffer = new byte[stream.Length];
    stream.Read(buffer, 0, buffer.Length);

    //读完后跳到开始流的开始位置
    stream.Seek(0, SeekOrigin.Begin);
    return buffer;
}

 

 

 

将一个二进制数组转换成字符串

 

byte[] byteB=new byte[]{};
string str= System.Text.Encoding.UTF8.GetString(byteB);

 

 

 

将一个字符串转换成进制数组

 

string str = "你好，中国";
byte[] byteB = System.Text.Encoding.UTF8.GetBytes(str);

 

Object与byte[]的相互转换

/// 

/// 将Ojbect对象转换为byte数组
/// 
/// 被转换对象
/// 转换后byte数组
public static byte[] Object2Bytes(object obj)
{
    byte[] buff;
    using (MemoryStream ms = new MemoryStream())
    {
        IFormatter iFormatter = new BinaryFormatter();
        iFormatter.Serialize(ms, obj);
        buff = ms.GetBuffer();
    }
    return buff;
}

/// 

/// 将byte数组转换object成对象
/// 
/// 被转换byte数组
/// 转换完成后的对象
public static object Bytes2Object(byte[] buff)
{
    object obj;
    using (MemoryStream ms = new MemoryStream(buff))
    {
        IFormatter iFormatter = new BinaryFormatter();
        obj = iFormatter.Deserialize(ms);
    }
    return obj;
}
