C＃Excel有條件地剪切/粘貼單元格

Question

如何檢查我的兩列（I列和H列）以查看I列中是否有非空單元格，而H列中的單元格為空，然后將非空單元格從I列剪切並粘貼到空H列中的單元格。

舉一個更清晰的例子：

到目前為止，我的想法是這樣的：

xl.Range ColH = sourceSheet.UsedRange;
        xl.Range ColI = sourceSheet.UsedRange;
        string occupiedCellsH;
        string emptyCellsI;
        occupiedCellsH = ColH.ToString();
        emptyCellsI = ColI.ToString();

        if (string.IsNullOrEmpty(emptyCellsI) && occupiedCellsH != null)
        {
            ColH.Cells.Copy(ColI);;
        }

這將達到目的：

        const int hCol = 8;
        const int iCol = 9;

        //start at 1 as there are column headings
        for (int i = 1; i < sourceSheet.UsedRange.Rows.Count; i++)
        {
            if ((sourceSheet.cells[i, hCol].value??"").ToString()!="" && 
                (sourceSheet.cells[i, iCol].value??"").ToString()=="")
            {
                sourceSheet.cells[i, iCol].value = sourceSheet.cells[i, hCol].value;
                sourceSheet.cells[i, hCol].value = "";
            }
        } 

按照您的評論進行相反操作（假設您仍然需要這樣做）：

        const int hCol = 8;
        const int iCol = 9;

        //start at 1 as there are column headings
        for (int i = 1; i < sourceSheet.UsedRange.Rows.Count; i++)
        {
            if ((sourceSheet.cells[i, iCol].value??"").ToString()!="" && 
                (sourceSheet.cells[i, hCol].value??"").ToString()=="")
            {
                sourceSheet.cells[i, hCol].value = sourceSheet.cells[i, iCol].value;
                sourceSheet.cells[i, iCol].value = "";
            }
        }
