想了解C#仿密保卡功能的简单实现代码的相关内容吗，在本文为您仔细讲解C#仿密保卡的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：密保卡，下面大家一起来学习吧。

不过我写的比较草率，代码结构不是很好，也没有体现OOP的思想，这几天有空会重构一下。

先把代码发出来：

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;
        }
    }

调用：

复制代码代码如下:

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(); 
        }
