c#抽签系统如何实现

这篇文章将为大家详细讲解有关C#抽签系统如何实现，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

一个基于c#的简单抽签系统，可以重新导入数据，清空数据。
代码简单，比较适合初学者。

导入数据时会创建一个txt文本，可以在里面看到输入

private void button1_Click(object sender, EventArgs e)   //确定按钮        {            string path = System.io.Directory.GetCurrentDirectory() + "//name.txt";                  Random rand = new Random(System.Guid.NewGuid().GetHashCode());                            string[] name = File.ReadAllLines(path);                                      if (name.Length == 0)            {                MessageBox.Show("导入数据不能为空！");            }            else            {                textBox1.Text = name[rand.Next(0, name.Length)];              //抽签                          textBox1.ForeColor = Color.Black;            }        }         private void button3_Click(object sender, EventArgs e)     //导入数据        {            string qkong = "";                                                               //清空name.TXT            string CurDir11 = System.AppDomain.CurrentDomain.BaseDirectory + @"name.txt.txt";                String filePath21 = CurDir11;            System.IO.StreamWriter file11 = new System.IO.StreamWriter(filePath21, false);     /            file11.Write(qkong);                                                                             file11.Close();                                                                               file11.Dispose();                                                                            string result = textBox2.Text.Trim();                                                      string d = System.AppDomain.CurrentDomain.BaseDirectory + @"name.txt";                String filePath = d;            System.IO.StreamWriter file1 = new System.IO.StreamWriter(filePath, false);                 file1.Write(result);                                                                          file1.Close();                                                                             file1.Dispose();                                                                            MessageBox.Show("导入成功");        }        private void button4_Click(object sender, EventArgs e)      //清空数据        {            string qkong = "";                                                                          string s = System.AppDomain.CurrentDomain.BaseDirectory + @"name.txt.txt";               String filePath21 = s;            System.IO.StreamWriter file11 = new System.IO.StreamWriter(filePath21, false);                 file11.Write(qkong);                                                                          file11.Close();                                                                              file11.Dispose();                                                                            textBox2.Text = "";        }        private void textBox2_TextChanged(object sender, EventArgs e)        {            this.textBox2.Multiline = true;        }
