只要將charnum改變就可以自定義設計生成隨機數的個數。

//獲取驗證碼的**

void getvalidatecode()

}//隨機碼的生成獲取5個隨機數字

static void main(string args)

console.writeline(str);

str = string.empty;

}console.read();

}//獲取5個隨機的大寫英文本母

string strran = "abcdefghijklmnopqrstuvwxyz";

string str = "";

system.random rom = new random();

int strnums = 5;

for (int i = 0; i < 8; i++)

console.writeline(str);

str = string.empty;
