C#打印控件的使用是如何的呢?我们在编写C#打印控件实用程序的时候怎么操作呢?首先弄一个printDocument控件,然后在打印的按钮中直接调用printDocument1.print()事件. 再次就是写printDocument的PrintPag事件了. 下面C#打印控件的使用具体实例:
- //C#打印控件的使用实例
- private void button1_Click(object sender, EventArgs e)
- {
- printDocument1.Print();
- }
- private void printDocument1_PrintPage(object sender,
- System.Drawing.Printing.PrintPageEventArgs e)
- {
- Font tabelTextFont = new Font("宋体", 10);
- if (dataGridView1.DataBindings != null)
- {
- int[] columnsWidth =
- new int[dataGridView1.Columns.Count];
- //C#打印控件的使用之得到所有列的个数
- int[] columnsLeft=new int[dataGridView1.Columns.Count];
- //for (int c = 0; c < columnsWidth.Length; c++)
- //C#打印控件的使用之得到列标题的宽度
- {
- columnsWidth[c] = (int)e.Graphics.MeasureString(
- dataGridView1.Columns[c].HeaderText , tabelTextFont).Width;
- }
- for (int rowIndex = 0;
- rowIndex < dataGridView1.Rows.Count; rowIndex++)
- //C#打印控件的使用之rowindex当前行
- {
- for (int columnIndex = 0;
- columnIndex < dataGridView1.Columns.Count; columnIndex++)
- //C#打印控件的使用之当前列
- {
- int w = (int)e.Graphics.MeasureString(
- dataGridView1.Columns[columnIndex].Name ,
- tabelTextFont).Width; columnsWidth[columnIndex] =
- w > columnsWidth[columnIndex] ? w : columnsWidth[columnIndex];
- }
- }//C#打印控件的使用
- int rowHidth = 20;
- int tableLeft=60;
- int tableTop=70;
- columnsLeft[0]=tableLeft;
- for (int i=1;i<=columnsWidth.Length -1;i++)
- {
- columnsLeft[i] = columnsLeft[i - 1] + columnsWidth[i - 1]+15;
- }
- StringFormat sf=new StringFormat ();
- sf.Alignment=StringAlignment.Center ;//居中打印
- e.Graphics.DrawString("欢迎石印死了开的交流!",
- new Font("宋体", 15), Brushes.Black, new Point(
- e.PageBounds.Width / 2, 20),sf );//打印标题
- for (int c = 0; c < columnsWidth.Length; c++)
- //打印表中的列名
- {
- e.Graphics.DrawString(dataGridView1.Columns[c].HeaderText,
- new Font ("宋体",10,FontStyle.Bold),
- Brushes.Black, new Point(columnsLeft[c], tableTop));
- e.Graphics.DrawLine(Pens.Black,
- new Point(columnsLeft[c]-5, tableTop - 5),
- new Point(columnsLeft[c]-5, tableTop +
- (dataGridView1 .Rows .Count+1)*rowHidth));
- }//C#打印控件的使用
- e.Graphics.DrawLine(Pens.Black,
- new Point(columnsLeft[dataGridView1.Columns.Count - 1] +
- columnsWidth[dataGridView1.Columns.Count - 1],
- tableTop - 5), new Point(columnsLeft[dataGridView1.Columns.Count - 1] +
- columnsWidth[dataGridView1.Columns.Count - 1],
- tableTop + (dataGridView1.Rows.Count + 1) * rowHidth));
- //画***面的线
- e.Graphics.DrawLine(Pens.Black, new Point(columnsLeft[0] - 5,
- tableTop - 5), new Point(columnsLeft[dataGridView1.Columns.Count - 1] +
- columnsWidth[dataGridView1.Columns.Count - 1], tableTop - 5));
- for (int rowIndex = 0;
- rowIndex < dataGridView1.Rows.Count; rowIndex++)//打印表中的内容
- {
- for (int columnIndex = 0;
- columnIndex < dataGridView1.Columns.Count; columnIndex++)
- {
- e.Graphics.DrawString(
- dataGridView1.Rows[rowIndex].Cells[columnIndex].Value.ToString(),
- tabelTextFont, Brushes.Black, new Point(columnsLeft[columnIndex],
- tableTop + rowHidth * (rowIndex + 1)));
- }
- e.Graphics.DrawLine(Pens.Black,
- new Point(columnsLeft[0]-5,
- tableTop + (rowIndex +1) * rowHidth-5),
- new Point(columnsLeft[dataGridView1.Columns.Count - 1] +
- columnsWidth[dataGridView1.Columns.Count - 1], tableTop +
- (rowIndex +1)*rowHidth-5));//循环画行
- }
- //C#打印控件的使用之
- }
另外要是想有打印预览的话,那就还要一个printPreviewDialog控件了。要把该控件的document事件和PrintDocument关联起来,就可以了。
C#打印控件的使用的实例应用就向你介绍到这里,希望对你了解和学习C#打印控件的使用有所帮助。
