C # simple implementation code of the anti-password protection card function

However, I wrote it rashly. The code structure is not very good and it does not reflect the idea of OOP. I will refactor it in the past few days.

First, send the Code:

Copy codeThe Code is as follows: public class MatrixCardManager
{
Public static int [,] ReadMatrixCardFromString (string matrixStr)
{
Int [,] arr1 = new int [5, 5];
Int [] tempArr = new int [25];
Int k = 0;
String [] tempArrStr = matrixStr. Split (',');
For (int I = 0; I <tempArr. Length; I ++)
{
TempArr [I] = Convert. ToInt32 (tempArrStr [I]);
}
For (int I = 0; I <5; I ++)
{
For (int j = 0; j <5; j ++)
{
Arr1 [I, j] = tempArr [k];
K ++;
}
}
Return arr1;
}

Public static string SaveMatrixIntoString (int [,] arr)
{
String matrixStr = String. Empty;
Int [] lineArr = new int [25];
Int k = 0;
For (int I = 0; I <5; I ++)
{
For (int j = 0; j <5; j ++)
{
LineArr [k] = arr [I, j];
K ++;
}
}
For (int I = 0; I <lineArr. Length; I ++)
{
MatrixStr + = lineArr [I];
If (I <24)
{
MatrixStr + = ",";
}
}
Return matrixStr;
}

Public static void PrintMatrix (int [,] arr)
{
Console. WriteLine ("| A \ tB \ tC \ tD \ tE ");
Console. WriteLine ("-------------------------------------------");
For (int k = 0; k <5; k ++)
{
Console. Write (k + "| ");
For (int l = 0; l <5; l ++)
{
Console. Write (arr [k, l] + "\ t ");
}
Console. WriteLine ();
}
}

Public static int [,] GenerateRandomMatrix ()
{
Random r = new Random ();
Int [,] arr = new int [5, 5];
For (int I = 0; I <5; I ++)
{
For (int j = 0; j <5; j ++)
{
Arr [I, j] = r. Next (0,100 );
}
}
Return arr;
}

Public static char GetColCode (int colIndex)
{
Char colCode = '-';
Switch (colIndex)
{
Case 0:
ColCode = 'a ';
Break;
Case 1:
ColCode = 'B ';
Break;
Case 2:
ColCode = 'C ';
Break;
Case 3:
ColCode = 'D ';
Break;
Case 4:
ColCode = 'E ';
Break;
Default:
Break;
}
Return colCode;
}

Public static bool Validate (int [,] arr, int colIndex1, int rowIndex1, int colIndex2, int rowIndex2, int colIndex3, int rowIndex3, string userInput, bool validFlag)
{
Try
{
String [] inputArr = userInput. Split (',');

Bool OK0 = arr [rowIndex1, colIndex1] = Convert. ToInt32 (inputArr [0]);
Bool OK1 = arr [rowIndex2, colIndex2] = Convert. ToInt32 (inputArr [1]);
Bool OK2 = arr [rowIndex3, colIndex3] = Convert. ToInt32 (inputArr [2]);

If (OK0 & OK1 & OK2)
{
ValidFlag = true;
}
Else
{
ValidFlag = false;
}
}
Catch (Exception)
{
Console. WriteLine ("Oh ,**! ");
}
Return validFlag;
}
}

Call:

Copy codeThe Code is as follows: static void Main (string [] args)
{
Console. WriteLine ("Generate and Print Matrix Card: \ n ");
Int [,] arr = MatrixCardManager. GenerateRandomMatrix ();
MatrixCardManager. PrintMatrix (arr );
Console. WriteLine ("\ n ");

Console. WriteLine ("Save Matrix Card into string for storage: \ n ");
String matrixStr = MatrixCardManager. SaveMatrixIntoString (arr );
Console. WriteLine (matrixStr );
Console. WriteLine ("\ n ");

Console. WriteLine ("Read Matrix Card from string: \ n ");
Int [,] arr1 = MatrixCardManager. ReadMatrixCardFromString (matrixStr );
MatrixCardManager. PrintMatrix (arr1 );
Console. WriteLine ("\ n ");

Console. WriteLine ("Matrix Card Validation: \ n ");
Random r = new Random ();

Int colIndex1 = r. Next (0, 4 );
Int rowIndex1 = r. Next (0, 4 );
Char colCode1 = MatrixCardManager. GetColCode (colIndex1 );

Int colIndex2 = r. Next (0, 4 );
Int rowIndex2 = r. Next (0, 4 );
Char colCode2 = MatrixCardManager. GetColCode (colIndex2 );

Int colIndex3 = r. Next (0, 4 );
Int rowIndex3 = r. Next (0, 4 );
Char colCode3 = MatrixCardManager. GetColCode (colIndex3 );

Console. writeLine ("Please Input Card Number At {0} {1}, {2} {3}, {4} {5}: \ n", colCode1, rowIndex1, colCode2, rowIndex2, colCode3, rowIndex3 );

String userInput = Console. ReadLine ();

Bool validFlag = false;
ValidFlag = MatrixCardManager. Validate (arr, colIndex1, rowIndex1, colIndex2, rowIndex2, colIndex3, rowIndex3, userInput, validFlag );
If (validFlag)
{
Console. WriteLine ("All input are correct! ");
}
Else
{
Console. WriteLine ("Sorry, your input were wrong! ");
}
Console. ReadKey ();
}
