请大家看看这个语句是不是有错误(在线等)

Question

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

Answer 1

sr1
sr2是什么都不知道~~
叫我们怎么看

Answer 2

Peek函数能用么？我的映像中好像只能用ReadLine然后判断PositionSr1和Sr2是StreamReader么？

Answer 3

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?

Answer 4

sr1,sr2是两个流文件,读入两个 文本,然后比较两个文本中的内容,有相同的 则提出来

Answer 5

都改成 .Peek() >= 0 试试

Answer 6

while (sr2.Peek()>0)
                {
                    str1 = sr1.ReadLine();  ？？？            
                    str2 = sr2.ReadLine();
                    str3 = str2.Substring(5);

Answer 7

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;
                }
            }
        }
