求助求助大佬，卡两天了

旧问题走了，新问题出现了
for (int i = 0; i < ar4.Count; i++) //ar4.Count=3
{
System.Collections.ArrayList tt = new System.Collections.ArrayList();
for (int j = Convert.ToInt32(ar4[i]); j < blines; j++)
{
string[] sArray = strs[j].Split(new char[2] { ':', ',' });
for (int p = 0; p < sArray.Length; p++)
{
ListViewItem item = new ListViewItem(sArray[p]);
listView1.Items.Add(item);
}
if (!strs[j].Contains("-----------------------------------------"))
{
if (strs[j].Contains("mdtrt_id"))
{
tt.Add(sArray[13]);
// t1 = Convert.ToString(sArray[13]);
// MessageBox.Show(t1);
}
else
{
tt.Add("aaa");
}
}
else
{
break;
}
}
//art6 = tt.Clone() as System.Collections.ArrayList;
t1 = Convert.ToString(tt[i]);
MessageBox.Show(t1);
}
循环到第三次，tt不存数据了，彩虹字体处报错，超出索引范围

openFileDialog1.Title = "请选择文件夹";
openFileDialog1.Filter = "txt文件(*.txt)|*.txt";
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string file = openFileDialog1.FileName;
strs = System.IO.File.ReadAllLines(file, System.Text.Encoding.Default);
blines = strs.Length;
for (int i = 0; i < blines; i++)//i=5
{
if (strs[i].Contains("【2401】入院办理入参"))
{
ar1.Add(i);
}
if (strs[i].Contains("【2401】入院办理出参"))
{
ar4.Add(i);
}
if (strs[i].Contains("【2304】住院结算入参"))
{
ar2.Add(i);
}
if (strs[i].Contains("【2304】住院结算出参"))
{
ar5.Add(i);
}
else {
}
}
这个是读取代码

这个是我写的窗体，很捞

tt中没有值，可不超出索引么

解决了，等我项目解决贴个代码
