對一維碼。以及二維碼生成進行配置生成，并且可以實作添加文字内容實作x，y軸定位坐标位置
1.以下方法是生成一維碼，二維碼，文字的通用方法
/// <summary>
/// 添加字型方法
/// </summary>
/// <param name="g">Graphics g ，目标Graphics對象 </param>
/// <param name="drawPoint">PointF drawPoint，存儲坐标位置</param>
/// <param name="data">string data ，準備添加的字元串</param>
/// <param name="size">大小</param>
private void AddFont(Graphics g, PointF drawPoint, string data, int size)
{
SolidBrush mybrush = new SolidBrush(Color.Black); //設定預設畫刷顔色
Font myfont = new Font("宋體", size, FontStyle.Regular); //設定預設字型格式
g.DrawString(data, myfont, mybrush, drawPoint); //圖檔上添加文字
//重新整理pictureBox調用此方法：pictureBox1.Refresh();
}

/// <param name="width">二維碼寬度</param>
/// <param name="height">二維碼高度</param>
private void CreateQRCode(Graphics g, PointF drawPoint, string data, int width, int height)
{

#region 根據設定的目标圖檔尺寸調整二維碼QRCodeScale設定

} 2.在這裡通過winform的按鈕事件去調用，也可以根據實際操作去調用
/// <summary>
/// 生成按鈕
/// </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("條碼内容以及文字内容必須填寫一項");
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("條碼内容不為空，請填寫完整的條碼資訊内容");
return;
}
if (radioButton2.Checked)
{
if (txt_QrCodeWidth.Text != txt_QrCodeHeight.Text)
{
MessageBox.Show("二維碼的寬度，高度應該保持一緻");
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内容不為空，請填寫完整的文字1資訊内容");
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内容不為空，請填寫完整的文字2資訊内容");
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内容不為空，請填寫完整的文字3資訊内容");
return;
}
}
Bitmap bitmap = new Bitmap(pictureBox1.Width, pictureBox1.Height);
//建立 Graphics 對象，将pictureBox1作為背景圖像進行内容的背景圖像
Graphics graphics = Graphics.FromImage(bitmap);
////添加一個白色畫布
//Rectangle Rec = new Rectangle(0, 0, pictureBox1.Width, pictureBox1.Height);
//SolidBrush mySolidBrush = new SolidBrush(Color.White);
//graphics.FillRectangle(mySolidBrush, Rec);
//當條碼内容部分資料不為空，界面顯示條碼
if (!string.IsNullOrWhiteSpace(txt_QrCode.Text))
{
PointF DrawPoint = new PointF(Convert.ToInt32(txt_QrCodeX.Text), Convert.ToInt32(txt_QrCodeY.Text));
//判斷是否是一維碼或者是二維碼
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));
}
//當文字1内容部分資料不為空，界面顯示内容1的資料
if (!string.IsNullOrWhiteSpace(txt_Font1_Content.Text))
{
//建立 PointF 有序列類存儲 float x，float y的資料（内容的坐标軸位置）
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));
}
//當文字2内容部分資料不為空，界面顯示内容1的資料
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));
}
//當文字3内容部分資料不為空，界面顯示内容1的資料
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));
}
//重新整理pictureBox1
pictureBox1.Image = bitmap;
} 3.在這裡通過winform的按鈕事件去清空界面，通過周遊窗體的内部控件元素，進行删除
/// <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)
{
//周遊整個窗體的元素
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);
////添加一個透明畫布
//Rectangle Rec = new Rectangle(0, 0, pictureBox1.Width, pictureBox1.Height);
//SolidBrush mySolidBrush = new SolidBrush(Color.Transparent);
//graphics.FillRectangle(mySolidBrush, Rec);
//((PictureBox)item).Image = bitmap;
}
}
} 最後呈現結果
