c 打印控件怎麽用

c#打印控件的使用是如何的呢？我們在編寫C#打印控件實用程序的時候怎麽操作呢？首先弄壹個printDocument控件,然後在打印的按鈕中直接調用printDocument1.print()事件. 再次就是寫printDocument的PrintPag事件了. 下面C#打印控件的使用具體實例：

//C#打印控件的使用實例 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("宋體", 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個數 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標題的寬度 { 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當前行 { for (int columnIndex = 0; columnIndex < dataGridView1.Columns.Count; columnIndex++) //C#打印控件的使用之當前列 { 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("歡迎石印死了開的交流!", new Font("宋體", 15), Brushes.Black, new Point( e.PageBounds.Width / 2, 20),sf );//打印標題 for (int c = 0; c < columnsWidth.Length; c++) //打印表中的列名 { e.Graphics.DrawString(dataGridView1.Columns[c].HeaderText, new Font ("宋體",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)); //畫最後面的線 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++)//打印表中的內容 { 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));//循環畫行 } //C#打印控件的使用之 }
