C#在Excel中将连续多列相同数据项合并

效果图如下：

/**//// /// 合并工作表中指定行数和列数数据相同的单元格 /// /// 工作表索引 /// 开始行索引 /// 开始列索引 /// 要合并的行数 /// 要合并的列数         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; } } } } }
