c# 在wince上 读excel csv txt 的方法

在wince 上对excel 文件的支持比较少，读比较麻烦，可以把excel 文件另存为csv文件，csv文件可以改后缀变成txt文件。

读txt的时候用 string.splite 分隔之下面是我自己写的只读的类

using System;using System.Linq;using System.Collections.Generic;using System.Text;using System.IO;using System.Windows.Forms;using System.Reflection;namespace demo_rfcom_wince{    class csvFile    {        private  StreamReader m_StreamReader;        private string[] m_StrArry;        private int m_FileLinesCount = 0;        public csvFile(string name)        {            string cvsFileName;            cvsFileName  =  System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().ManifestModule.FullyQualifiedName)+"\\"+name;            m_StreamReader = new StreamReader(cvsFileName, Encoding.Default);            while(m_StreamReader.ReadLine()!=null)m_FileLinesCount++;            m_StrArry = new string[m_FileLinesCount+1];            //load            int i;            m_StreamReader.BaseStream.Position = 0;            for (i = 0; i < m_FileLinesCount; i++)m_StrArry[i] = m_StreamReader.ReadLine();        }        ~csvFile()        {            m_StreamReader.Close();        }        public int GetLinesCount()        {            return m_FileLinesCount;        }        public string Read(int x, int y)        {            if (y > m_FileLinesCount) return null;            string[] r = new string[128];            r = m_StrArry[y].Split(',');            return r[x];        }    }}
