1.合並拆分數組

/// <summary>
         /// 合並數組
         /// </summary>
         /// <param name="First"> 第一個數組 </param>
         /// <param name="Second"> 第二個數組 </param>
         /// <returns> 合並后的數組(第一個數組+第二個數組，長度為兩個數組的長度) </returns>
         public string[] MergerArray( string[] First, string[] Second)
        {
             string[] result = new string[First.Length + Second.Length];
            First.CopyTo(result, 0);
            Second.CopyTo(result, First.Length);
             return result;
        }

         /// <summary>
         /// 數組追加
         /// </summary>
         /// <param name="Source"> 原數組 </param>
         /// <param name="str"> 字符串 </param>
         /// <returns> 合並后的數組(數組+字符串) </returns>
         public string[] MergerArray( string[] Source, string str)
        {
             string[] result = new string[Source.Length + 1];
            Source.CopyTo(result, 0);
            result[Source.Length] = str;
             return result;
        }

         /// <summary>
         /// 從數組中截取一部分成新的數組
         /// </summary>
         /// <param name="Source"> 原數組 </param>
         /// <param name="StartIndex"> 原數組的起始位置 </param>
         /// <param name="EndIndex"> 原數組的截止位置 </param>
         /// <returns></returns>
         public string[] SplitArray( string[] Source, int StartIndex, int EndIndex)
        {
             try
            {
                 string[] result = new string[EndIndex - StartIndex+ 1];
                 for ( int i = 0; i <= EndIndex - StartIndex; i++) result[i] = Source[i+StartIndex];
                 return result;
            }
             catch (IndexOutOfRangeException ex)
            {
                 throw new Exception(ex.Message);
            }
        }

         /// <summary>
         /// 不足長度的前面補空格,超出長度的前面部分去掉
         /// </summary>
         /// <param name="First"> 要處理的數組 </param>
         /// <param name="byteLen"> 數組長度 </param>
         /// <returns></returns>
         public string[] MergerArray( string[] First, int byteLen)
        {
             string[] result;
             if (First.Length > byteLen)
            {
                result = new string[byteLen];
                 for ( int i = 0; i < byteLen; i++) result[i] = First[i + First.Length - byteLen];
                 return result;
            }
             else
            {
                result = new string[byteLen];
                 for ( int i = 0; i < byteLen; i++) result[i] = " ";
                First.CopyTo(result, byteLen-First.Length);
                 return result;
            }
        }

2.調用

string[] student1 = { " a ", " b ", " c ", " d ", " e ", " f "};
string[] student2 = { " 0 ", " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 6 ", " 1 ", " 8 ", " 16 ", " 10 ", " 45 ", " 37 ", " 82 " };
string student3 = " Test ";
// 兩個數組相加結果--> { "a", "b", "c", "d", "e", "f","0", "1", "2", "3", "4", "5", "6", "6", "1", "8", "16", "10", "45", "37", "82" };
string[] Merger1 = MergerArray(student1, student2);
// 數組+字符串結果-->{ "a", "b", "c", "d", "e", "f","Test"};
string[] Merger2 = MergerArray(student1, student3);
// 不足10位的，前面補空格結果-->{" ", " ", " ", " ", "a", "b", "c", "d", "e", "f"};
string[] Merger3 = MergerArray(student1, 10);
// 超過3位的，只取最后3后結果-->{"d", "e", "f"};
string[] Merger4 = MergerArray(student1, 3);
// 截取部分數組結果-->{"c", "d", "e"};
string[] SplitArray1 = SplitArray(student1, 2, 4);
