推荐答案

您可以按原样插入字符串-

You can insert string as is -

command.CommandText = "INSERT INTO User (username) VALUE ('David')");

此外，您可以将数据作为十六进制值插入，使用Encoding.GetBytes方法获取分支数组，然后将字节转换为十六进制字符串(编写特殊函数)，结果应如下所示-

Also, you can insert data as a hex value, use Encoding.GetBytes method to get array of butes, then convert bytes to a hex string (write special function), the result should be like this -

command.CommandText = "INSERT INTO User (username) VALUE (0x4461766964)");
