Asp.net (c #) two random number algorithms, available for question Extraction

The first algorithm has a big problem. Not found Copy codeThe Code is as follows: static void Main (string [] args)
{
//
// TODO: Add code here to start the application
Int singletitlemeasure = 5;
Int n = 1; // declare an int variable that represents the test Type
Random ran = new Random (unchecked (int) DateTime. Now. Ticks ));
Int Int1Random;
Switch (n)
{
Case 1: // indicates a single answer
{
Int I = 1, k = 1;
Int [] ** I = new int [singletitlemeasure + 1]; // declare an array used to save question numbers
Int temp; // declare an array that temporarily saves random values
Int1Random = ran. Next (1, singletitlemeasure );
** I = Int1Random;
Console. WriteLine ("** I [" + I + "] =" + ** I );
Do
{K = 1; Int1Random = ran. Next (1, singletitlemeasure); temp = Int1Random; Console. WriteLine ("temp:" + temp); do {if (temp! = ** I [k]) {

{Console. Write ("Int1Random ="); Console. WriteLine (** I );
} Break;
}
Case 2: // indicates multiple choice questions {Console. WriteLine ("Int2Random ="); break;
}
Case 3: // indicates a question.
{
