对一维码。以及二维码生成进行配置生成，并且可以实现添加文字内容实现x，y轴定位坐标位置
1.以下方法是生成一维码，二维码，文字的通用方法
/// <summary>

/// </summary>
/// <param name="g">Graphics g ，目标Graphics对象 </param>
/// <param name="drawPoint">PointF drawPoint，存储坐标位置</param>

private void AddFont(Graphics g, PointF drawPoint, string data, int size)
{
SolidBrush mybrush = new SolidBrush(Color.Black); //设置默认画刷颜色
Font myfont = new Font("宋体", size, FontStyle.Regular); //设置默认字体格式
g.DrawString(data, myfont, mybrush, drawPoint); //图片上添加文字
//刷新pictureBox调用此方法：pictureBox1.Refresh();
}

/// <param name="data">string data ，准备添加的字符串</param>
/// <param name="width">二维码宽度</param>
/// <param name="height">二维码高度</param>
private void CreateQRCode(Graphics g, PointF drawPoint, string data, int width, int height)
{
QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();
qrCodeEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;
qrCodeEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M;
qrCodeEncoder.QRCodeScale = 3; //作为初始定义，没有实际意义
qrCodeEncoder.QRCodeVersion = 7; //二维码生成的类型，
//Encoding.UTF8为必备参数，否则某些中文字符无法识别
System.Drawing.Image image = qrCodeEncoder.Encode(data, Encoding.UTF8);
#region 根据设定的目标图片尺寸调整二维码QRCodeScale设置
if (width > 0)
{
//当设定目标图片尺寸大于生成的尺寸时，逐步增大方格尺寸
#region 当设定目标图片尺寸大于生成的尺寸时，逐步增大方格尺寸
while (image.Width < width)
{
qrCodeEncoder.QRCodeScale++;

if (imageNew.Width < width)
{

imageNew.Dispose();
imageNew = null;
}
else
{
qrCodeEncoder.QRCodeScale--; //新尺寸未采用，恢复最终使用的尺寸
imageNew.Dispose();
imageNew = null;
break;
}
}
#endregion
//当设定目标图片尺寸小于生成的尺寸时，逐步减小方格尺寸
#region 当设定目标图片尺寸小于生成的尺寸时，逐步减小方格尺寸
while (image.Width > width && qrCodeEncoder.QRCodeScale > 1)
{

imageNew.Dispose();
imageNew = null;
if (image.Width < width)
{
break;
}
}
#endregion
}
#endregion
g.DrawImage(image, drawPoint);
}

{

} 2.在这里通过winform的按钮事件去调用，也可以根据实际操作去调用
/// <summary>
/// 生成按钮
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button2_Click(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(txt_QrCode.Text) && string.IsNullOrWhiteSpace(txt_Font1_Content.Text) && string.IsNullOrWhiteSpace(txt_Font2_Content.Text) && string.IsNullOrWhiteSpace(txt_Font3_Content.Text))
{
MessageBox.Show("条码内容以及文字内容必须填写一项");
return;
}
if (!string.IsNullOrWhiteSpace(txt_QrCode.Text))
{
if (string.IsNullOrWhiteSpace(txt_QrCodeX.Text) || string.IsNullOrWhiteSpace(txt_QrCodeY.Text) || string.IsNullOrWhiteSpace(txt_QrCodeWidth.Text) || string.IsNullOrWhiteSpace(txt_QrCodeHeight.Text))
{
MessageBox.Show("条码内容不为空，请填写完整的条码信息内容");
return;
}
if (radioButton2.Checked)
{
if (txt_QrCodeWidth.Text != txt_QrCodeHeight.Text)
{
MessageBox.Show("二维码的宽度，高度应该保持一致");
return;
}
}
}
if (!string.IsNullOrWhiteSpace(txt_Font1_Content.Text))
{
if (string.IsNullOrWhiteSpace(txt_Font1_X.Text) || string.IsNullOrWhiteSpace(txt_Font1_Y.Text) || string.IsNullOrWhiteSpace(txt_Font1_Size.Text))
{
MessageBox.Show("文字1内容不为空，请填写完整的文字1信息内容");
return;
}
}
if (!string.IsNullOrWhiteSpace(txt_Font2_Content.Text))
{
if (string.IsNullOrWhiteSpace(txt_Font2_X.Text) || string.IsNullOrWhiteSpace(txt_Font2_Y.Text) || string.IsNullOrWhiteSpace(txt_Font2_Size.Text))
{
MessageBox.Show("文字2内容不为空，请填写完整的文字2信息内容");
return;
}
}
if (!string.IsNullOrWhiteSpace(txt_Font3_Content.Text))
{
if (string.IsNullOrWhiteSpace(txt_Font3_X.Text) || string.IsNullOrWhiteSpace(txt_Font3_Y.Text) || string.IsNullOrWhiteSpace(txt_Font3_Size.Text))
{
MessageBox.Show("文字3内容不为空，请填写完整的文字3信息内容");
return;
}
}
Bitmap bitmap = new Bitmap(pictureBox1.Width, pictureBox1.Height);
//创建 Graphics 对象，将pictureBox1作为背景图像进行内容的背景图像
Graphics graphics = Graphics.FromImage(bitmap);
////添加一个白色画布
//Rectangle Rec = new Rectangle(0, 0, pictureBox1.Width, pictureBox1.Height);
//SolidBrush mySolidBrush = new SolidBrush(Color.White);
//graphics.FillRectangle(mySolidBrush, Rec);
//当条码内容部分数据不为空，界面显示条码
if (!string.IsNullOrWhiteSpace(txt_QrCode.Text))
{
PointF DrawPoint = new PointF(Convert.ToInt32(txt_QrCodeX.Text), Convert.ToInt32(txt_QrCodeY.Text));
//判断是否是一维码或者是二维码
if (radioButton2.Checked)
CreateQRCode(graphics, DrawPoint, txt_QrCode.Text, Convert.ToInt32(txt_QrCodeWidth.Text), Convert.ToInt32(txt_QrCodeHeight.Text));
else if (radioButton1.Checked)
CreateBrCode(graphics, DrawPoint, txt_QrCode.Text, Convert.ToInt32(txt_QrCodeWidth.Text), Convert.ToInt32(txt_QrCodeHeight.Text));
}
//当文字1内容部分数据不为空，界面显示内容1的数据
if (!string.IsNullOrWhiteSpace(txt_Font1_Content.Text))
{
//创建 PointF 有序列类存储 float x，float y的数据（内容的坐标轴位置）
PointF DrawPoint = new PointF(Convert.ToInt32(txt_Font1_X.Text), Convert.ToInt32(txt_Font1_Y.Text));
AddFont(graphics, DrawPoint, txt_Font1_Content.Text, Convert.ToInt32(txt_Font1_Size.Text));
}
//当文字2内容部分数据不为空，界面显示内容1的数据
if (!string.IsNullOrWhiteSpace(txt_Font2_Content.Text))
{
PointF DrawPoint = new PointF(Convert.ToInt32(txt_Font2_X.Text), Convert.ToInt32(txt_Font2_Y.Text));
AddFont(graphics, DrawPoint, txt_Font2_Content.Text, Convert.ToInt32(txt_Font2_Size.Text));
}
//当文字3内容部分数据不为空，界面显示内容1的数据
if (!string.IsNullOrWhiteSpace(txt_Font3_Content.Text))
{
PointF DrawPoint = new PointF(Convert.ToInt32(txt_Font3_X.Text), Convert.ToInt32(txt_Font3_Y.Text));
AddFont(graphics, DrawPoint, txt_Font3_Content.Text, Convert.ToInt32(txt_Font3_Size.Text));
}
//刷新pictureBox1
pictureBox1.Image = bitmap;
} 3.在这里通过winform的按钮事件去清空界面，通过遍历窗体的内部控件元素，进行删除
/// <summary>
/// 清空姐界面内容
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click(object sender, EventArgs e)
{
//遍历整个窗体的元素
foreach (Control item in this.Controls)
{
//如果是文本框
if (item is TextBox)
{
item.Text = null;
}
if (item is PictureBox)
{
//方法一：
((PictureBox)item).Image = null;
////方法二：
////清空picture内容
//Bitmap bitmap = new Bitmap(pictureBox1.Width, pictureBox1.Height);
//Graphics graphics = Graphics.FromImage(bitmap);
////添加一个透明画布
//Rectangle Rec = new Rectangle(0, 0, pictureBox1.Width, pictureBox1.Height);
//SolidBrush mySolidBrush = new SolidBrush(Color.Transparent);
//graphics.FillRectangle(mySolidBrush, Rec);
//((PictureBox)item).Image = bitmap;
}
}
} 最后呈现结果
