C#把字符串变成字节并计算字节长度

Answer 1

string str = "ConvertString2Bytes";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(str);

中文的用
string str = "中文";
byte[] bytes = System.Text.Encoding.GetEncoding("GB2312").GetByteCount(str);
int Length = bytes.Length;

Answer 2

string str = "ConvertString2Bytes";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(str); int Length = bytes.Length;

Answer 3

string str="hello!";
byte[] buf=Encoding.ASCII.GetBytes(str);
Console.Write(buf.Length);
楼主，不知道你是不是要这个？

int byteLen = System.Text.Encoding.Default.GetByteCount("字符串")
