二進制到對應的ASCII字符串轉換

Question

嗨，我能夠將ASCII字符串轉換爲二進制使用binarywriter ..作爲10101011。即時通訊需要回轉換Binary --->ASCII字符串..任何想法如何做到這一點？

Answer 1

這應該做的伎倆......或者至少讓你開始...

public Byte[] GetBytesFromBinaryString(String binary) 
{ 
    var list = new List<Byte>(); 

    for (int i = 0; i < binary.Length; i += 8) 
    { 
    String t = binary.Substring(i, 8); 

    list.Add(Convert.ToByte(t, 2)); 
    } 

    return list.ToArray(); 
} 

一旦二進制字符串已被轉換爲一個字節數組，完成了與

Encoding.ASCII.GetString(data); 

所以......

var data = GetBytesFromBinaryString("010000010100001001000011"); 
var text = Encoding.ASCII.GetString(data); 

Answer 2

以此爲一個簡單的例子：

public void ByteToString() 
{ 
    Byte[] arrByte = { 0, 1, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0 }; 

    string x = Convert.ToBase64String(arrByte); 
} 

這個鏈接的回答有關於這種轉換的有趣的細節：

binary file to string

Answer 3

下面是完整的代碼爲您answer

FileStream iFile = new FileStream(@"c:\test\binary.dat", 
FileMode.Open); 

long lengthInBytes = iFile.Length; 

BinaryReader bin = new BinaryReader(aFile); 

byte[] byteArray = bin.ReadBytes((int)lengthInBytes); 

System.Text.Encoding encEncoder = System.Text.ASCIIEncoding.ASCII; 

string str = encEncoder.GetString(byteArray); 

Answer 4

如果你有ASCII碼只有你可以使用Encoding.ASCII.GetBytes和Encoding.ASCII.GetString。

var text = "Test"; 
var bytes = Encoding.ASCII.GetBytes(text); 
var newText = Encoding.ASCII.GetString(bytes); 

Answer 5

Sometim ES，而不是使用內置的工具，最好使用「自定義」代碼..試試這個功能：

public string BinaryToString(string binary) 
{ 
    if (string.IsNullOrEmpty(binary)) 
     throw new ArgumentNullException("binary"); 

    if ((binary.Length % 8) != 0) 
     throw new ArgumentException("Binary string invalid (must divide by 8)", "binary"); 

    StringBuilder builder = new StringBuilder(); 
    for (int i = 0; i < binary.Length; i += 8) 
    { 
     string section = binary.Substring(i, 8); 
     int ascii = 0; 
     try 
     { 
      ascii = Convert.ToInt32(section, 2); 
     } 
     catch 
     { 
      throw new ArgumentException("Binary string contains invalid section: " + section, "binary"); 
     } 
     builder.Append((char)ascii); 
    } 
    return builder.ToString(); 
} 

與010000010100001001000011測試它使用「原始」的ASCII值返回ABC。
