我写的：
default.aspx.cs的代码：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
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;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
char code;
int number;
string checkCode = String.Empty;
Random r = new Random();
for(int i=0;i<8;i++)
{
number = r.Next();
code = (char)('0' + (char)(number % 10));
checkCode += code.ToString();
}
this.TextBox2.Text = this.TextBox1.Text + checkCode;
}
}
default.aspx的代码：
