ARR =【】
问题1、在不删除非数据内容的情况下怎么把数据内容读入二维数组里 ？
问题2、怎么把数据写入最后的ARR=【】数组里 ？
本人是菜鸟、希望大家多多帮忙 ！！

楼主，你这个txt文档，以空格做分隔符，给你个写好的：
public static List<String[]> ReadTxt(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(' ')); //以空格做分隔符
//Debug.WriteLine(strLine);
}
}
fileReader.Close();
return ls;
}
你在此基础上，做二次分析，相信会了吧。。。。
