求解。代码如下：
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Text;
public class ValidateCode
{
public ValidateCode()
{
}

public string validateCode()

{

byte[] bytes = new byte[100];

Random randObj = new Random();

int code;

for (int i = 0; i < 4; i++)

{

code = randObj.Next(44, 122);

bytes = Convert.ToByte(code);

}

ASCIIEncoding ascii = new ASCIIEncoding();

string validateCode = ascii.GetString(bytes,0,4);

return validateCode.ToString();

}
}
以上，请问这段代码有什么作用？
