如何使用C＃中的单元格值设置Excel图表的位置？

我正在使用以下方法来创build和放置表格数据旁边的Excel图表。 下面的代码工作正常，但图表位置（高度）创build问题时，图表数量增加。

有单元格绘制图表的解决scheme吗？ 或其他可能被我用来保持图表旁边的数据的东西。

我想逐页打印下面的方法的结果，因此要把它正确地放置。

下面是我的代码：

Excel.Application xla = new Excel.Application(); int height=75; string uppercell = "B12"; int cell = 12; if (CheckBox1.Checked == true) { string table_name, chart_name; table_name = "Ration Table"; chart_name = "Ratio"; string st = ""; con.Open(); trying(ws, st, height, uppercell, cell, table_name, chart_name); con.Close(); cell = cell + 33; uppercell = "B" + cell; height = 496 + 75;//height + 300; } public void trying(Excel.Worksheet ws,string st,double height,string uppercell,int cell,string table_name,string chart_name) { MySqlDataAdapter da = new MySqlDataAdapter(st, con); System.Data.DataTable dtMainSQLData = new System.Data.DataTable(); da.Fill(dtMainSQLData); DataColumnCollection dcCollection = dtMainSQLData.Columns; //int cell = System.Int32.Parse(uppercell.Substring(1));
