把错误提示贴出来啊！

Random r = new Random();
txt.Text = r.Next();

代码贴出来,应该可以看出什么地方的错误的.
你说的是Winform还是WebForm程序呀?

/// <summary>
/// 随机生成指定长度的密码（由a--z0-9组成）
/// </summary>
/// <param name="passwordLength">密码长度</param>
/// <returns></returns>
private static string creatPassword(int passwordLength)
{
string randomchars = "abcdefghijklmnopqrstuvwxyz0123456789";
int iRandNum;
char[] pass = new char[passwordLength];
Random rnd = new Random();
for (int i = 0; i < passwordLength; i++)
{
iRandNum = rnd.Next(randomchars.Length);
pass[i] = randomchars[iRandNum];
}
return new string(pass);
}

Random r = new Random();
textBox1.Text = r.Next(99999).ToString();

估摸着是WebFrom

int Length=0;
int Up=1;
int Down=0;
int iFirst = 0;
int[] rtArray = new Int32[Length];
Random ro = new Random(Length* unchecked((int)DateTime.Now.Ticks));
iFirst = ro.Next(Down,Up);
rtArray[0] = iFirst;
for (int i = 1; i < Length; i++)
{
Random ri = new Random(i * iFirst * unchecked((int)DateTime.Now.Ticks));
rtArray[i] = ri.Next(Down,Up);
iFirst = rtArray[i];
}
LblNum.Text = rtArray.ToString();

int Length=0;
int Up=1;
int Down=0;
int iFirst = 0;
int[] rtArray = new Int32[Length];
Random ro = new Random(Length* unchecked((int)DateTime.Now.Ticks));
iFirst = ro.Next(Down,Up);
rtArray[0] = iFirst;
for (int i = 1; i < Length; i++)
{
Random ri = new Random(i * iFirst * unchecked((int)DateTime.Now.Ticks));
rtArray[i] = ri.Next(Down,Up);
iFirst = rtArray[i];
}
LblNum.Text = rtArray.ToString();
这是我写的代码是webFrom
