我正在遵循这篇文章的建议并尝试释放我的所有 COM 对象，包括所有范围，同时将字符串元组列表写入 Excel 电子表格（使用他的 ComObjectManager 类）。

我有下面的解决方案，但看起来没有堆叠由

cells[j, column] = strings[i].Item1;

（等）在 ComObjectManager 对象中，因此不释放它们。我有注释掉的解决方案，它会释放对象，但我不能正确理解语法来设置单元格，因为它不会编译。我也尝试过使用

var roomNameCell = com.Get<object>(() => cells[j, column]);

对于 roomNameCell 和 areaCell，但这不会导致单元格中没有写入任何内容。

我已经研究了 MSDN 指南，但无法弄清楚如何做到这一点，请帮忙。

internal void InsertStrings(List<Tuple<string, string>> strings, Excel.Range selection, ComObjectManager com)
    {
        const int singleRowCell = 1;
        const int columnsToArea = 2;

        int firstRow = selection.Row;
        int column = selection.Column;

        for (int i = 0, j = firstRow; i < strings.Count; )
        {
            selection = com.Get<Excel.Range>(() => app.Cells[j, column]);

            var mergeArea = com.Get<Excel.Range>(() => selection.MergeArea);
            var mergeAreaRows = com.Get<Excel.Range>(() => mergeArea.Rows);

            var cells = com.Get<Excel.Range>(() => app.Cells);

            if (selection.MergeCells && mergeAreaRows.Count > singleRowCell)
            {
                //var roomNameCell = com.Get<Excel.Range>(() => cells[j, column]);
                //var areaCell = com.Get<Excel.Range>(() => cells[j, column + columnsToArea]);

                //doesn't compile - cannont explicity convert from string to Range
                //roomNameCell = strings[i].Item1;
                //areaCell = strings[i].Item2;

                //works but the Range COM objects aren't being disposed?
                cells[j, column] = strings[i].Item1;
                cells[j, column + columnsToArea] = strings[i].Item2;
                ++i;
            }
            j += mergeAreaRows.Count;
        }
    }

我想通了，我只需要像这样设置 Values 属性：

internal void InsertStrings(List<Tuple<string, string>> strings, Excel.Range selection, ComObjectManager com)
    {
        const int singleRowCell = 1;
        const int columnsToArea = 2;

        int firstRow = selection.Row;
        int column = selection.Column;

        for (int i = 0, j = firstRow; i < strings.Count; )
        {
            selection = com.Get<Excel.Range>(() => app.Cells[j, column]);

            var mergeArea = com.Get<Excel.Range>(() => selection.MergeArea);
            var mergeAreaRows = com.Get<Excel.Range>(() => mergeArea.Rows);

            var cells = com.Get<Excel.Range>(() => app.Cells);

            if (selection.MergeCells && mergeAreaRows.Count > singleRowCell)
            {
                var roomNameCell = com.Get<Excel.Range>(() => cells[j, column]);
                var areaCell = com.Get<Excel.Range>(() => cells[j, column + columnsToArea]);

                roomNameCell.Value = strings[i].Item1;
                areaCell.Value = strings[i].Item2;

                ++i;
            }
            j += mergeAreaRows.Count;
        }
    }
