在Excel中将连续多列相同数据项合并

效果图如下:


代码如下:
/// <summary>
        
/// 合并工作表中指定行数和列数数据相同的单元格
        
/// </summary>
        
/// <param name="sheetIndex">工作表索引</param>
        
/// <param name="beginRowIndex">开始行索引</param>
        
/// <param name="beginColumnIndex">开始列索引</param>
        
/// <param name="rowCount">要合并的行数</param>
        
/// <param name="columnCount">要合并的列数</param>

        public void MergeWorkSheet(int sheetIndex,int beginRowIndex,int beginColumnIndex,int rowCount,int columnCount)
        
{

            
//检查参数
            if ( columnCount < 1 || rowCount < 1)
                
return ;

            
for(int col=0;col<columnCount;col++)
            
{
                
int mark = 0;            //标记比较数据中第一条记录位置
                int mergeCount = 1;        //相同记录数,即要合并的行数
                string text = "";
                
                
for(int row=0;row<rowCount;row++)
                
{
                    
string prvName = "";
                    
string nextName = "";

                    
//最后一行不用比较
                    if( row + 1 < rowCount)        
                    
{
                        
for(int n=0;n<=col;n++)
                        
{
                            range 
= (Excel.Range)workSheet.Cells[row + beginRowIndex,n + beginColumnIndex];
                            range 
= (Excel.Range)range.MergeArea.get_Item(1,1);
                            text 
= range.Text.ToString();
                            prvName 
= prvName + text;

                            range 
= (Excel.Range)workSheet.Cells[row + 1 + beginRowIndex,n + beginColumnIndex];
                            range 
= (Excel.Range)range.MergeArea.get_Item(1,1);
                            nextName 
= nextName + range.Text.ToString();

                        }

                            
                        
if(prvName == nextName)
                        
{
                            mergeCount
++;

                            
if(row == rowCount - 2)
                            
{
                                
this.MergeCells(sheetIndex,beginRowIndex + mark,beginColumnIndex + col,beginRowIndex + mark + mergeCount - 1,beginColumnIndex + col,text);
                            }

                        }

                        
else
                        
{
                            
this.MergeCells(sheetIndex,beginRowIndex + mark,beginColumnIndex + col,beginRowIndex + mark + mergeCount - 1,beginColumnIndex + col,text);
                            mergeCount 
= 1;
                            mark 
= row + 1;
                        }

                            
                    }
        
                }

            }

        }
