本文实例为大家分享了一个读写csv文件的C#类，供大家参考，具体内容如下
using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
namespace CSVDemo
{
/// <summary>
/// CSVUtil is a helper class handling csv files.
/// </summary>
public class CSVUtil
{
private CSVUtil()
{
}
//write a new file, existed file will be overwritten
public static void WriteCSV( string filePathName,List<String[]>ls)
{
WriteCSV(filePathName, false ,ls);
}
//write a file, existed file will be overwritten if append = false
public static void WriteCSV( string filePathName, bool append, List<String[]> ls)
{
StreamWriter fileWriter= new StreamWriter(filePathName,append,Encoding.Default);
foreach (String[] strArr in ls)
{
fileWriter.WriteLine(String.Join ([,",strArr) );
}
fileWriter.Flush();
fileWriter.Close();
}
public static List<String[]> ReadCSV( string filePathName)
{
List<String[]> ls = new List<String[]>();
StreamReader fileReader= new StreamReader(filePathName);
string strLine= "" ;
while (strLine != null )
{
strLine = fileReader.ReadLine();
if (strLine != null && strLine.Length>0)
{
ls.Add(strLine.Split( ',' ));
//Debug.WriteLine(strLine);
}
}
fileReader.Close();
return ls;
}
}
}
