代码不对吧？
Random ra = new Random();
int R = ra.Next();
string str = txtuserpwd.Text;
string Encryption(string str, Random R);
SqlCommand cmd1 = new SqlCommand("insert into userinfo values('" + txtusername.Text + "','pwd')", conn);
cmd1.ExecuteNonQuery();
这里面的这句：string Encryption(string str, Random R); 是干什么的？看来应该是函数调用，但是为什么没有变量？
而且您的事件处理函数为什么都没有“object sender, EventArgs e”参数？
这段代码的问题太多了啊，您是不是帖错了代码？
string Encryption(string str, Random R);
我学C#也没多久,其它的不知道有什么问题,但是至少这句话是不对的.反回的值需要存在一个变量里面,你不能用这样方法来定义得到的返回值.
还有,你程序的写法太像ASP了...
