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 filePath11 = CurDir11;
System.IO.StreamWriter file11 = new System.IO.StreamWriter(filePath11, 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 filePath11 = s;
System.IO.StreamWriter file11 = new System.IO.StreamWriter(filePath11, false);
file11.Write(qkong);
file11.Close();
file11.Dispose();
textBox2.Text = "";
}
private void textBox2_TextChanged(object sender, EventArgs e)
{
this.textBox2.Multiline = true;
}
