Question

我正在尝试连接excel文件中的两列并将其保存到新列。但是如果一个值为空，我想忽略连接。并转移到下一个单元格。

            Excel.Worksheet exampst = (Excel.Worksheet)Sh.get_Item("Sheet2");
            Excel.Range rng2 = (Excel.Range)exampst.get_Range("H1", Type.Missing);
            rng2.EntireColumn.Insert(Microsoft.Office.Interop.Excel.XlInsertShiftDirection.xlShiftToRight,                                        Microsoft.Office.Interop.Excel.XlInsertFormatOrigin.xlFormatFromRightOrBelow);
            exampst.Range["H1", Type.Missing].Value2 = "CombineID";
            Excel.Range rgcon2 = exampst.Range["H2"];
            //Excel.Range rng3 = (Excel.Range)RFCst.get_Range("G2", Type.Missing);
            //object obj = rng3.Value2;
            rgcon2.Formula = String.Format("=CONCATENATE(A2,G2)");

我的Excel表格如下所示。A1 G1 H1 1 a 1a //this is the concatenated value. 2 //This value b as null,as G1 column has missing row value. 3 b 3b 4 c 4c 5 d 5d 6 7 e 7e 8 f 8f 9 and so on....
请帮忙。

在连接之前，如果它们为空或空，则需要首先检查A列和G列中单元格中的值。你可以这样做：

object rangeObject = activeWorksheet.Cells[3, "A"];
Range range = (Range)rangeObject;
object rangeValue = range.Value2;
string cellValue1 = rangeValue.ToString();

rangeObject = activeWorksheet.Cells[3, "G"];
range = (Range)rangeObject;
rangeValue = range.Value2;
string cellValue2 = rangeValue.ToString();

if (cellValue1 != string.Empty && cellValue2 != string.Empty)
{
   //concatenate cells
}

使用c＃基于excel中的值进行条件格式化/连接
