1. 写一个导出按钮，点击导出按钮导出数据
private void button4_Click(object sender, EventArgs e)
{
//如果需要导出的dataGridView4中有数据
if (dataGridView4.Rows.Count > 0)
{
string order_id = textOrderDay.Text.ToString();
string string1 = textArtDay.Text.Trim();
string string2 = GetShoeTyesName(art, order_id);
string string3 = GetProcessingUnit(order_id);
string string4 = richTextDay.Text.Trim();
string string5 ="时间";
string type = comboBox3.Text.ToString();
if (type.Equals("送料"))
{
ExtelMyself("送料日配套报表", dataGridView4, string1 , string2 , string3 ,string4 ,string5 );
}
else if (type.Equals("回料"))
{
ExtelMyself("回料日配套报表", dataGridView4, string1 , string2 , string3 ,string4 ,string5 );
}else
{
MessageBox.Show("不能明确配套报表类型");
}
}
}
2. 编写导出数据的函数
public void ExtelMyself(string fileName, DataGridView myDGV, string art,string shoeTypeName,string processing_unit,string po,string date)

}
worksheet.Name = fileName;
