请大家看看这个语句是不是有错误(在线等)
while (sr1.Peek()> 0)
{
str1 = sr1.ReadLine();
MessageBox.Show( "sr1 "+str1);
while (sr2.Peek()> 0)
{
str2 = sr2.ReadLine();
str3 = str2.Substring(5);
MessageBox.Show( "sr2 "+str3);
if (str1.Equals(str3) == true)
{
MessageBox.Show( "hello ");
str1 = str1 + str2.Substring(0,5);
sw.WriteLine(str1);
}

}
}
问题:第一次循环的时候可以进入到第二个while中,以后就不能了,不知道为什么

[解决办法]
Peek函数能用么？我的映像中好像只能用ReadLine然后判断Position

Sr1和Sr2是StreamReader么？
[解决办法]
StreamReader中Peek到最后就返回-1 能用
不知道sr1 sr2读的是什么怎么看?
[解决办法]
都改成 .Peek() > = 0 试试
[解决办法]
while (sr2.Peek()> 0)
{
str1 = sr1.ReadLine(); ？？？
str2 = sr2.ReadLine();
str3 = str2.Substring(5);

[解决办法]
StreamReader read1 = new StreamReader (@ "c:\1.txt ");

StreamReader read2 = new StreamReader(@ "c:\3.txt ");
ArrayList aList1 = new ArrayList();
ArrayList aList2 = new ArrayList();
while(read1.Peek() > 0)
{
aList1.Add(read1.ReadLine());
}
while (read2.Peek() > 0)
{
aList2.Add(read2.ReadLine());
}
for (int i = 0; i < aList1.Count; i++)
{
for (int j = 0; j < aList2.Count; j++)
{
if(aList1[i].ToString().Equals(aList2[j].ToString()))
{
Response.Write(aList1[i].ToString()+ " <br> ");
break;
}
}
}
