毕业后工作单位第一个工作：好坑~~~！
一个简单的小DEMO
各位大神勿喷
生成：

public partial class FrmImage1 : Form
{
public FrmImage1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string enCodeString = this.textBox1.Text;
QRCodeEncoder qrce = new QRCodeEncoder();
this.pictureBox1.Image = qrce.Encode(enCodeString,Encoding.UTF8);
}
private void button2_Click(object sender, EventArgs e)
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Jpg图像|*.jpg|Bmp图像|*.bmp";
sfd.Title = "保存图像";
if (sfd.ShowDialog() == DialogResult.OK)
{
pictureBox1.Image.Save(sfd.FileName);
}
}
private void button3_Click(object sender, EventArgs e)
{
FrmImage2 frm2 = new FrmImage2();
this.Hide();
frm2.ShowDialog();
