如何在C#中将excel中的一列数据存储到string[]中

How to store a column of data in excel to string[] in C#

我有一个这样的 string[] 成员:

private string[] mStrings = null;

构造函数中的代码如下:

Excel.Application excelApp = new Excel.Application();
Excel.Workbook excelWorkBook = excelApp.Workbooks.Open(excel_file_path);
Excel.Worksheet excelWorkSheet = (Excel.Worksheet)excelWorkBook.Sheets[2]; // I get the data from the second sheet

我想把F列的数据存储到mStrings中,所以我写了这样的代码:

mStrings = excelWorkSheet.Columns["F"].Value2;

这段代码是错误的,那么正确的代码是什么?谢谢!

可能有更好的方法来解决这个问题,但我设法解决了你的问题,方法是在列中获取 UsedRange,然后使用简单的 'for' 循环遍历该列,将值存储到列表中字符串,然后将列表传递给字符串数组

        string[] mColumn = null;
        List<string> mlstColumn = new List<string>();

        // get used range of column F
        Range range = excelWorkSheet.UsedRange.Columns["F", Type.Missing];

        // get number of used rows in column F
        int rngCount = range.Rows.Count;

        // iterate over column F's used row count and store values to the list
        for (int i = 1; i <= rngCount; i++)
        {
            mlstColumn.Add(excelWorkSheet.Cells[i, "F"].Value.ToString());
        }

        // List<string> --> string[]
        mColumn = mlstColumn.ToArray();

        // remember to Quit() or the instance of Excel will keep running in the background
        excelApp.Quit();
