C# 如何将字节数组转换为字符串

How to convert byte array to string

提问by Oksana

I created a byte array with two strings. How do I convert a byte array to string?

我用两个字符串创建了一个字节数组。如何将字节数组转换为字符串？

var binWriter = new BinaryWriter(new MemoryStream());
binWriter.Write("value1");
binWriter.Write("value2");
binWriter.Seek(0, SeekOrigin.Begin);

byte[] result = reader.ReadBytes((int)binWriter.BaseStream.Length);

I want to convert resultto a string. I could do it using BinaryReader, but I cannot use BinaryReader(it is not supported).

我想转换result为字符串。我可以使用BinaryReader，但我不能使用BinaryReader（它不受支持）。

Depending on the encoding you wish to use:

根据您希望使用的编码：

var str = System.Text.Encoding.Default.GetString(result);

Assuming that you are using UTF-8 encoding:

假设您使用的是 UTF-8 编码：

string convert = "This is the string to be converted";

// From string to byte array
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(convert);

// From byte array to string
string s = System.Text.Encoding.UTF8.GetString(buffer, 0, buffer.Length);

You can do it without dealing with encoding by using BlockCopy:

您可以使用BlockCopy在不处理编码的情况下做到这一点：

char[] chars = new char[bytes.Length / sizeof(char)];
System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length);
string str = new string(chars);

To convert the byte[] to string[], simply use the below line.

要将 byte[] 转换为 string[]，只需使用以下行。

byte[] fileData; // Some byte array
//Convert byte[] to string[]
var table = (Encoding.Default.GetString(
                 fileData, 
                 0, 
                 fileData.Length - 1)).Split(new string[] { "\r\n", "\r", "\n" },
                                             StringSplitOptions.None);
