我想不过来获得一个工作表中的最低值,当我生成最小,并将其放置在一个单元格,然后提取该值我得到整个公式,而不是在细胞的双重价值....我做错了什么?下面是我的生成图的方法。如何获得一个值,而不是公式

另一件事,我也想删除图形后,我将它保存我试图.delete(),但只是把和错误,我怎么去这样做

private void GenerateGraph(Worksheet worksheet, int lastRow, int lastColumn, string filename) 
     { 
      string topLeft = ToCell(0, 0); 
      string bottomRight = ToCell(lastRow - 1, lastColumn - 1); 



     worksheet.get_Range(ToCell(0, 0), missing).Formula = "Max(B2:" + bottomRight + ")"; 
     worksheet.get_Range(ToCell(0, 0), missing).FormulaHidden = true; 
     worksheet.get_Range(ToCell(0, 0), missing).Calculate(); 
     Range range = (Range)worksheet.Cells[1,1]; 

     // 
     //here is where my problem is, small is being given the formula from above 
     // 

     string small = (string)range.Value2; 
     double min = Convert.ToDouble(small); 
     worksheet.get_Range(ToCell(0,0),missing).Formula = ""; 

     //Generates the graph 
     range = worksheet.get_Range(topLeft, bottomRight); 
     ChartObjects Xlchart = (ChartObjects)worksheet.ChartObjects(missing); 
     ChartObject chart = (ChartObject)Xlchart.Add(20, 160, 600, 500); 
     Excel.Chart myChart = chart.Chart; 
     myChart.SetSourceData(range, missing); 

     //sets the y axis 
     Axis axis = (Axis)myChart.Axes(XlAxisType.xlValue, XlAxisGroup.xlPrimary); 
     axis.MinimumScaleIsAuto = true; 
     axis.MaximumScaleIsAuto = true; 
     axis.HasTitle = true; 
     axis.AxisTitle.Text = "Measure (m)"; 
     axis.CrossesAt = (int)(min-1); 

     //sets the x axis 
     Axis xAxis = (Axis)myChart.Axes(XlAxisType.xlCategory, XlAxisGroup.xlPrimary); 
     xAxis.HasTitle = true; 
     xAxis.AxisTitle.Text = "Position (m)"; 

     //makes the graph a line graph 
     myChart.ChartType = XlChartType.xlXYScatterLinesNoMarkers; 

     //titles the graph 
     myChart.HasTitle = true; 
     myChart.ChartTitle.Text = "Profiles"; 

     //saves the graph 
     myChart.Export(filename, "JPG", missing); 

     // 
     //here is where I would like to delete the graph 
     // 
    }

您需要:

Formula = "=Max(B2:" + bottomRight + ")" 

您错过了公式中的等号。

那我,那解决我的问题的前半部分,现在我该怎样从实际Excel中删除图形文件? – 2011-02-23 14:54:59

@Bob这是有问两个问题一个问题。我知道第一个答案,但不是第二个答案。你会更好编辑这个问题上的删除部分,然后要求只包含一个新的问题! – 2011-02-23 15:02:49
