最近再学习一下正则表达式 写了个小工具自己测试

好久没写Form 代码了,手都有点痒了..

写了个正则表达式测试软件

代码很少命名规范这些 就忽略了哈...呵呵

 1 private void textBox2_TextChanged(object sender, EventArgs e)
 2         {
 3             if (textBox2.Text != "" && textBox1.Text!="")
 4             {
 5                 if (checkBox1.Checked)
 6                 {
 7                     textBox3.Text = "";
 8                 }
 9                 try
10                 {
11                     MatchCollection c = Regex.Matches(textBox2.Text, textBox1.Text);
12                     foreach (Match item in c)
13                     {
14                         textBox3.Text = textBox3.Text + item.Value + "\r\n";
15                     }
16                 }
17                 catch (Exception ex)
18                 {
19                     textBox3.Text = textBox3.Text + ex.Message + "\r\n";
20                 }
21                 textBox3.SelectionStart = textBox3.Text.Length; //使滚动条在最下
22                 textBox3.ScrollToCaret();
23             }
24         }
25 
26         private void button1_Click(object sender, EventArgs e)
27         {
28             textBox3.Text = "";
29         }
