可能重复：
How do you convert a string to ascii to binary in C#?

如何将字符串（例如"Hello"）转换为二进制序列为1011010？

Answer 1

试试这个：

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

Answer 2

string result = string.Empty;
foreach(char ch in yourString)
{
   result += Convert.ToString((int)ch,2);
}

这会将"Hello"翻译为10010001100101110110011011001101111

Answer 3

string testString = "Hello";
UTF8Encoding encoding = new UTF8Encoding();
byte[] buf = encoding.GetBytes(testString);

StringBuilder binaryStringBuilder = new StringBuilder();
foreach (byte b in buf)
{
    binaryStringBuilder.Append(Convert.ToString(b, 2));
}
Console.WriteLine(binaryStringBuilder.ToString());

Answer 4

使用BitConverter获取字符串的字节，然后将这些字节格式化为二进制表示形式：

byte[] bytes = System.Text.Encoding.Default.GetBytes( "Hello" );
StringBuilder sb = new StringBuilder();
foreach ( byte b in bytes )
{
    sb.AppendFormat( "{0:B}", b );
}
string binary = sb.ToString();
