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; 
} 
} 
}
