使用WPF中的開放XML以單元格值爲單元格着色

我已經使用Open XML導出了excel中的數據，現在我需要根據單元格值爲幾列的單元格添加顏色。

我採取幫助從下面的鏈接做出口： http://justgeeks.blogspot.com/2012/03/writing-large-amounts-of-data-from.html

誰能幫我用塗色部分。我的數據在數據表中。

嘗試下面的代碼...

using System; 
using System.Collections.Generic; 
using System.Linq;

    protected void Grd_QADetails_RowDataBound(object sender, GridViewRowEventArgs e) 
    { 
     if (e.Row.RowType == DataControlRowType.DataRow) 
     { 
      var dataRowView = e.Row.DataItem as DataRowView; 
      DataRow row = dataRowView.Row; 

      var Current = (row["Dosage"] as int?) ?? null; 


      if (Current != null) 
      { 
       if (Current >= 1 && Current < 10) 
        e.Row.Cells[1].BackColor = Color.Green; 

       else if (Current >= 10 && Current < 20) 
        e.Row.Cells[1].BackColor = Color.Yellow; 

       else 
        e.Row.Cells[1].BackColor = Color.Red; 
      } 
     } 
    } 

    protected void Page_Load(object sender, EventArgs e) 
    {
