c#如何操作excel文件、Interior.ColorIndex 色彩列表

创建、打开、读取、写入、保存的一般性代码： using System;
using System.Reflection; // 引用这个才能使用Missing字段 namespace CExcel1
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
//创建Application对象
Excel.Application xApp=new Excel.ApplicationClass(); xApp.Visible=true;
//得到WorkBook对象, 可以用两种方式之一: 下面的是打开已有的文件
Excel.Workbook xBook=xApp.Workbooks._Open(@"D:\Sample.xls",
Missing.Value,Missing.Value,Missing.Value,Missing.Value
,Missing.Value,Missing.Value,Missing.Value,Missing.Value
,Missing.Value,Missing.Value,Missing.Value,Missing.Value);
//xBook=xApp.Workbooks.Add(Missing.Value);//新建文件的代码
//指定要操作的Sheet，两种方式： 

Excel.Worksheet xSheet=(Excel.Worksheet)xBook.Sheets[1];
//Excel.Worksheet xSheet=(Excel.Worksheet)xApp.ActiveSheet; //读取数据，通过Range对象
Excel.Range rng1=xSheet.get_Range("A1",Type.Missing);
Console.WriteLine(rng1.Value2); //读取，通过Range对象，但使用不同的接口得到Range
Excel.Range rng2=(Excel.Range)xSheet.Cells[3,1];
Console.WriteLine(rng2.Value2); //写入数据
Excel.Range rng3=xSheet.get_Range("C6",Missing.Value);
rng3.Value2="Hello";
rng3.Interior.ColorIndex=6; //设置Range的背景色 //保存方式一：保存WorkBook
xBook.SaveAs(@"D:\CData.xls",
Missing.Value,Missing.Value,Missing.Value,Missing.Value,Missing.Value,
Excel.XlSaveAsAccessMode.xlNoChange,Missing.Value,Missing.Value,Missing.Value,
Missing.Value,Missing.Value); //保存方式二：保存WorkSheet
xSheet.SaveAs(@"D:\CData2.xls",
Missing.Value,Missing.Value,Missing.Value,Missing.Value,
Missing.Value,Missing.Value,Missing.Value,Missing.Value,Missing.Value); //保存方式三
xBook.Save(); xSheet=null;
xBook=null;
xApp.Quit(); //这一句是非常重要的，否则Excel对象不能从内存中退出
xApp=null;
}
}
}
