c#，winform打印，实现打印预览，设置打印头，打印datagridview中部分数据，并且自定义datagridview中列的宽度
关于打印，我研究了一阵子，网上找了一大堆，但是没有我想要的，然后自己用最原始的方法，利用绘图工具Pen,Brush,Font一个个画出来的
完整的代码在最下面，大家复制后显示表头改一下汉字里面对应的自己datagridview中的列名就好了，显示表体改一下datagridview中列在Select中对应的下标就可以了。代码不难理解，就是画框框，大家可以复制后，慢慢调，改参数，慢慢玩就懂了
还有一个点：单击datagridview在属性里面找到截图这个：设置未为false，不让会空指针异常！！！！！！！
最后的效果如下：
图里面分三个部分：
第一个部分就是加粗字体的标题，页头和页尾的一下信息。
第二部分为datagridview中的部分列表的内容在打印中显示。
第三部分就是将合计对应的列打印出来。
接下来我就要介绍实现步骤了，数据在datagridview中显示和统计我就不介绍了，直接开始介绍打印的模板是怎么画出来的
在窗体中添加printDialog，printDocument，peintPreviewDialog，pageSetupDialog这四个控件
1、双击printDialog，在属性里面Document中选中关联printDocument1
2、双击peintPreviewDialog，在属性里面Document中选中关联printDocument1
3、双击pageSetupDialog，在属性里面Document中选中关联printDocument1
4、双击printDocument，在时间里面双击printPage
打印代码在这里面编写
接下来就是编码了、、、、、、
1、首先是图片上
表头的部分内容代码如下：
string rq = DateTime.Now.ToString("yyyy-MM-dd");
int num1 = 200;
StringFormat stringFormat = new StringFormat();
stringFormat.Alignment = StringAlignment.Center;
stringFormat.LineAlignment = StringAlignment.Center;
Pen pen = new Pen(Color.Black, 1f);
Font font = new Font("楷体", 24f, FontStyle.Bold);
Font font2 = new Font("楷体", 12f, FontStyle.Bold);
Brush black = Brushes.Black;
e.Graphics.DrawString("华禹科技采购入库单", font, black, 245f, 50f);
e.Graphics.DrawString("供应商：", font2, black, 100f, 110f);
e.Graphics.DrawString(textBox1.Text, font2, black, 150f, 110f);
e.Graphics.DrawString("备注：", font2, black, 100f, 130f);
e.Graphics.DrawString(textBox6.Text, font2, black, 150f, 130f);
e.Graphics.DrawString("日期：", font2, black, 300f, 110f);
e.Graphics.DrawString(sj1, font2, black, 350f, 110f);
e.Graphics.DrawString("编号：", font2, black, 500f, 110f);
e.Graphics.DrawString(textBox5.Text, font2, black, 550f, 110f);
e.Graphics.DrawString("仓库：", font2, black, 500f, 130f);
e.Graphics.DrawString(comboBox1.Text, font2, black, 550f, 130f);
内容和位置，大家可以复制此代码，改一下参数就好了
2、接下来就是打印datagridview列名的代码：红色标记的部分
代码如下：
foreach (var item in dataGridView2.Columns)
{
DataGridViewColumn dataGridViewColumn = (DataGridViewColumn)item;
if (dataGridViewColumn.HeaderText == "物料名称")
{
e.Graphics.DrawRectangle(pen, 100, 170, 220, 70);//画框框
e.Graphics.DrawString(dataGridViewColumn.HeaderText, new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(170, 160f, 80f, 50f), stringFormat);//在框框里面填写列名
}
if (dataGridViewColumn.HeaderText == "规格型号")
{
e.Graphics.DrawRectangle(pen, 320, 170, 120, 70);
e.Graphics.DrawString(dataGridViewColumn.HeaderText, new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(340, 160f, 80f, 50f), stringFormat);
}
if (dataGridViewColumn.HeaderText == "入库数量")
{
e.Graphics.DrawRectangle(pen, 440, 170, 80, 70);
e.Graphics.DrawString(dataGridViewColumn.HeaderText, new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(440, 160f, 80f, 50f), stringFormat);
}
if (dataGridViewColumn.HeaderText == "入库单价")
{
e.Graphics.DrawRectangle(pen, 520, 170, 80, 70);
e.Graphics.DrawString(dataGridViewColumn.HeaderText, new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(520, 160f, 80f, 50f), stringFormat);
}
if (dataGridViewColumn.HeaderText == "金额")
{
e.Graphics.DrawRectangle(pen, 600, 170, 60, 70);
e.Graphics.DrawString(dataGridViewColumn.HeaderText, new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(590, 160f, 80f, 50f), stringFormat);
}
if (dataGridViewColumn.HeaderText == "单位")
{
e.Graphics.DrawRectangle(pen, 660, 170, 60, 70);
e.Graphics.DrawString(dataGridViewColumn.HeaderText, new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(650, 160f, 80f, 50f), stringFormat);
}
}
3、最后就是显示列名下面表体的具体内容的代码了：
这里的横坐标和框框的宽度要与列名的一致，其他的大家根据自己慢慢调
for (int i = 0; i < dataGridView2.Rows.Count; i++)
{
for (int j = 0; j < dataGridView2.Columns.Count; j++)
{
if (j == 3)
{
e.Graphics.DrawRectangle(pen, 100, num1, 220, 40);
e.Graphics.DrawString(dataGridView2.Rows[i].Cells[j].Value.ToString(), new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(100f, (float)num1, 200f, 50f), stringFormat);
}
if (j == 4)
{
e.Graphics.DrawRectangle(pen, 320, num1, 120, 40);
e.Graphics.DrawString(dataGridView2.Rows[i].Cells[j].Value.ToString(), new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(320f, (float)num1, 100f, 50f), stringFormat);
}
if (j == 6)
{
e.Graphics.DrawRectangle(pen, 440, num1, 80, 40);
e.Graphics.DrawString(dataGridView2.Rows[i].Cells[j].Value.ToString(), new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(420f, (float)num1, 100f, 50f), stringFormat);
}
if (j == 7)
{
e.Graphics.DrawRectangle(pen, 520, num1, 80, 40);
e.Graphics.DrawString(dataGridView2.Rows[i].Cells[j].Value.ToString(), new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(500f, (float)num1, 100f, 50f), stringFormat);
}
if (j == 9)
{
e.Graphics.DrawRectangle(pen, 600, num1, 60, 40);
e.Graphics.DrawString(dataGridView2.Rows[i].Cells[j].Value.ToString(), new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(580f, (float)num1, 100f, 50f), stringFormat);
}
if (j == 10)
{
e.Graphics.DrawRectangle(pen, 660, num1, 60, 40);
e.Graphics.DrawString(dataGridView2.Rows[i].Cells[j].Value.ToString(), new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(640f, (float)num1, 100f, 50f), stringFormat);
}
}
num1 += 40;
}
最后还有一段代码就是图片箭头指示的内容，他说根据表体的内容增加而自动往下递增的，
该代码放到第三部第一个for循环外面：
放到这：
e.Graphics.DrawString("制单：", font2, black, 100f, num1+10);
e.Graphics.DrawString(User, font2, black, 150f, num1+10);
最后：我贴一下完整代码：
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
//button2.PerformClick();
try
{
bool flag = dataGridView2.Rows.Count > 0;
if (flag)
{
string rq = DateTime.Now.ToString("yyyy-MM-dd");
int num1 = 200;
StringFormat stringFormat = new StringFormat();
stringFormat.Alignment = StringAlignment.Center;
stringFormat.LineAlignment = StringAlignment.Center;
Pen pen = new Pen(Color.Black, 1f);
Font font = new Font("楷体", 24f, FontStyle.Bold);
Font font2 = new Font("楷体", 12f, FontStyle.Bold);
Brush black = Brushes.Black;
e.Graphics.DrawString("华禹科技采购入库单", font, black, 245f, 50f);
e.Graphics.DrawString("供应商：", font2, black, 100f, 110f);
e.Graphics.DrawString(textBox1.Text, font2, black, 150f, 110f);
e.Graphics.DrawString("备注：", font2, black, 100f, 130f);
e.Graphics.DrawString(textBox6.Text, font2, black, 150f, 130f);
e.Graphics.DrawString("日期：", font2, black, 300f, 110f);
e.Graphics.DrawString(sj1, font2, black, 350f, 110f);
e.Graphics.DrawString("编号：", font2, black, 500f, 110f);
e.Graphics.DrawString(textBox5.Text, font2, black, 550f, 110f);
e.Graphics.DrawString("仓库：", font2, black, 500f, 130f);
e.Graphics.DrawString(comboBox1.Text, font2, black, 550f, 130f);
foreach (var item in dataGridView2.Columns)
{
DataGridViewColumn dataGridViewColumn = (DataGridViewColumn)item;
if (dataGridViewColumn.HeaderText == "物料名称")
{
e.Graphics.DrawRectangle(pen, 100, 170, 220, 70);
e.Graphics.DrawString(dataGridViewColumn.HeaderText, new Font("楷体", 12f, FontStyle.Regular), Brushes.Black, new RectangleF(170, 160f, 80f, 50f), stringFormat);

}
