C#+arcengine獲得柵格資料的屬性表

  此文為或的柵格資料的屬性表的功能，在此，我的屬性表中有count和value欄位，其中value是柵格資料的高程值，count是value在影像中出現的次數，此程式的功能為得到count最大的數，以此來獲得對應的value即此柵格影像的高程值的眾數，如下：

  /// <summary>

        /// 獲得屬性表
        /// </summary>
        /// <param name="maskTifPath">raster的路徑</param>
        private int GetAttributeTable(string maskPath)
        {
           int elevation=0;//高程
            //得到raster（見另外的博文獲得柵格資料）
           IRaster raster=GetRaster(maskPath);
          if (raster != null)
           {
               try
                {
                 //得到一段光柵帶
                   IRasterBandCollection rasterBandCollection = (IRasterBandCollection)raster;
                  int bandCount = rasterBandCollection.Count;//bandCount=1
                   for (int j = 0; j < bandCount; j++)
                   {
                        IRasterBand rasterBand = rasterBandCollection.Item(j);
                      //得到此光柵帶的屬性表，並儲存到table
                        ITable table = rasterBand.AttributeTable;
                      //建立一個查詢（SQL語句）
                      IQueryFilter queryFilter = new QueryFilterClass();
                       queryFilter.WhereClause = "";
                       //用queryFilter查詢表，並把結果儲存到遊標指標中去
                       ICursor cursorCount = table.Search(queryFilter, false);
                        IRow rowCount = cursorCount.NextRow();
                        //  count欄位集合
                       List<int> countCol = new List<int>();
                       int MaxValue = 0;
                       for (int i = 0; i < table.Fields.FieldCount; i++)//field.count=4
                        {
                          //判斷欄位名稱是否為count
                           if (table.Fields.get_Field(i).Name == "Count")
                           {
                             while (rowCount != null)
                              {
                                    //以下顯示Count欄位的值，並得到count值的集合
                                  countCol.Add(Convert.ToInt32(rowCount.get_Value(table.FindField("Count"))));
                                   rowCount = cursorCount.NextRow();
                               }
                                int count = countCol.Count;
                                //得到欄位Count的最大值
                             MaxValue = countCol[0];
                               for (int w = 1; w < count; w++)
                               {
                                  if (countCol[w] > MaxValue)
                                   {
                                      MaxValue = countCol[w];
                                  }
                               }
                               //得到Count最大時value的值，即為高程的眾數
                              ICursor cursorBinvalues = table.Search(queryFilter, false);
                            IRow rowBinvalues = cursorBinvalues.NextRow();
                             while (rowBinvalues != null)
                              {
                                 int value = Convert.ToInt32(rowBinvalues.get_Value(table.FindField("Count")));
                                   if (value == MaxValue)
                               {
                                     elevation = Convert.ToInt32(rowBinvalues.get_Value(table.FindField("Value")));
                                 }
                                rowBinvalues = cursorBinvalues.NextRow();
                               }
                        }
                           else
                          {
                               //欄位名稱不是count，無用，往下判斷
                          }
                       }
                   }
                  return elevation;
             }
           catch (Exception ex)
               {
                  Console.WriteLine(ex.Message);
                  return 0;
               }
            }
           else
         {
               MessageBox.Show("提取柵格資料失敗！");
                return 0;
           }

       }
