小女子跪求求高手帮忙找错啊!!
题目:在CArray类里增加顺序查找方法,加快顺序查找方法,二分法以及递归二分法,并设一个compcount的私有整型变量,初始值为0,在每种查找的算法内,在执行完关键性比较后增加一行代码,对compcount进行加1操作。运行完四种方法后,比较compcount的值。  
我的代码如下:
    class CArray
     {
         private static int[] arr;
         private int numElements=0;
         private static int compCount=0;
         public CArray(int size)
         {
             arr = new int[size];
         }
         public void Insert(int item)
         {
             arr[numElements] = item;
             numElements++;
         }
         public void DisplayElements()
         {
             for (int i = 0; i <arr.Length; i++)
                 Console.Write(arr[i] + " ");
         }
         public void BubbleSort()
         {
             for (int outer = arr.Length-1; outer >= 1; outer--)
             {
                 for (int inner = 0; inner <= outer - 1; inner++)
                 {
                     if ((int)arr[inner] > arr[inner + 1])
                     {
                         swap(inner, inner + 1);
                     }
                 }
             }
         }
          private static void swap(int item1, int item2)
         {
             int temp = arr[item1];
             arr[item1] = arr[item2];
             arr[item2] = temp;
         }
          public int seqSearch(int sValue)
          {
              for (int index = 0; index < arr.Length; index++)
              {
                  if (arr[index] > sValue)
                  {
                      compCount = compCount + 1;
                      continue;
                  }
                  else
                      if (arr[index] < sValue)
                      {
                          compCount = compCount + 1;
                          continue;
                      }
                      else
                     {
                          return compCount;
                     }
              }
              return compCount;
          }
         public static int SeqSearch(int sValue)
         {
             for (int index = 0; index < arr.Length; index++)
             {
                 if (arr[index] > sValue)
                 {
                     compCount = compCount + 1;
                     continue;
                 }
                 else
                     if (arr[index] < sValue)
                     {
                         compCount = compCount + 1;
                         continue;
                     }
                     else
                     {
                         compCount = compCount + 1;
                         swap(index, 0);
                         return compCount;
                     }
             }
             return compCount;
         }
         public int binSearch(int value)
         {
             int upperBound, lowerBound, mid;
             upperBound = arr.Length - 1;
             lowerBound = 0;
             while (lowerBound <= upperBound)
             {
                 mid = (upperBound + lowerBound) / 2;
