关于C#的公车线路调用的程序，求各位大神帮忙
我假定了10条线路，button1的作用是起点到终点坐一条线直达，button2的作用是需换车的，但是button2有错误，运行不出来。（textBox1是起点，textBox2是终点）

namespace bus_station
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
string[] bus = new string[10];
private void button1_Click(object sender, EventArgs e)
{
string path = " ";
string aa = " ";
for (int i = 0; i < bus.Length; i++)
{
aa = bus[i];
if ((aa.IndexOf(textBox1.Text) >= 0) && (aa.IndexOf(textBox2.Text) >= 0))
{
string[] b = aa.Split(',');
path += b[0];
}
}
if (path != " ") textBox3.Text = path;
else textBox3.Text = "没有合适的线路";
}
private string tr(string a, string b)
{
string ret = " ";
string[] a1 = a.Split(',');
string[] b1 = b.Split(',');
for (int i = 0; i < a1.Length; i++)
{
for (int j = 0; j < b1.Length; j++)
{
if (a1[i] == b1[j])
{
if (ret == " ") ret = a1[i];
else ret += "," + a1[i];
}
}
}
return ret;
}
private void button2_Click(object sender, EventArgs e)
{
string path = " ";
string aa = " ", bb = " ",cc=" ";
for (int i = 0; i <bus.Length; i++)
{
aa = bus[i];
if (aa.IndexOf(textBox1.Text) >= 0)
{
for (int j = 0; j < bus.Length; j++)
if (i != j)
{
bb = bus[j];
if (bb.IndexOf(textBox2.Text) >= 0)
{
cc = tr(aa, bb);
if (cc != " ")
path += aa.Substring(0, 4) + "→" + cc+"转" + bb.Substring(0, 4) + "→" + textBox2.Text;
}
}
}
}
if (path != " ") textBox3.Text = path;
else textBox3.Text = "没有合适的线路";
}
private void Form1_Load(object sender, EventArgs e)

bus[2] = "#3,30,31,32,33,34,35,36,37,38,39";
bus[3] = "#4,40,41,42,43,44,45,46,47,48,49";
bus[4] = "#5,50,51,52,53,54,55,56,57,58,59";
bus[5] = "#6,60,61,62,63,64,65,66,67,68,69";
bus[6] = "#7,70,71,12,73,74,75,76,77,78,79";
bus[7] = "#8,80,81,82,83,84,85,86,87,88,89";
bus[8] = "#9,90,91,92,93,94,95,96,97,98,99";
bus[9] = "#10,00,01,02,03,04,05,06,07,08,09";
}
}
}
[解决办法]
你好，你的程序，我测试过了，如果是换乘一次的话，是正确的。你指的是什么错误？
