Byte conversion between C # char [] with the string [] Conversion between the string

1, the conversion between the char [] and the string

//string 转换成 Char[]
string str="hello";
char[] arr=str.ToCharArray();

//Char[] 转换成 string string str1 = new string(arr);

2, byte [] Conversion between the string

string str = "你好，hello";
byte[] bytes;
//byte[] 转换成 string
bytes = Encoding.UTF8.GetBytes(str);
//string 转换成 byte[] (字符串是用哪种编码生成的byte[],就要用那种编码合成string) string str1 = Encoding.UTF8.GetString(bytes); bytes=Encoding.Default.GetBytes(str); string str2 = Encoding.Default.GetString(bytes);
