写一个List <string>到Excel.Range
我有以下的excel范围：
workSheet.Range[workSheet.Cells[12, 2], workSheet.Cells[5000, 2]] 我已经把这个excel范围转换成列表，并在列表上执行一些数据操作。
object[,] cellValues = (object[,])inputRng.Value2; List<string> lst = cellValues.Cast<object>().ToList().ConvertAll(x => Convert.ToString(x));
我想将列表分配回Excel范围。
这里有一些你想要的开始代码，它可能会被改进。
你的主要问题是你从multidimensional array（ object[,] cellValues = (object[,])excelRange.Value; ）转换成List<string> – 如果你能以某种方式保持这个multidimensional array，会帮助你“设置”代码 – 这取决于你的其他代码在做什么。
当你想“设置”你的变化，我已经显示了两种方式来做到这一点：
-
或者迭代单元格（范围）并设置每个值
-
或提前提供一个multidimensional array值，并获得一次性使用它们的范围
