第三回 C#之初学Excel

#region DataGridView数据显示到Excel

public bool DataGridviewToExcel(DataGridView dgv, bool isShowExcle)
{
if (dgv.Rows.Count == 0)
return false;
//建立Excel对象
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
excel.Application.Workbooks.Add(true);
excel.Visible = isShowExcle;
//生成字段名称
for (int i = 0; i < dgv.ColumnCount; i++)
{
excel.Cells[1, i + 1] = dgv.Columns[i].HeaderText;
}
//填充数据
for (int i = 0; i < dgv.RowCount - 1; i++)
{
for (int j = 0; j < dgv.ColumnCount; j++)
{
if (dgv[j, i].ValueType == typeof(string))
{
excel.Cells[i + 2, j + 1] = "'" + dgv[j, i].Value.ToString();
}
else
{
excel.Cells[i + 2, j + 1] = dgv[j, i].Value.ToString();
}
}
}
excel.Workbooks.Close();//关闭表
excel.Quit();//退出Excel
return true;
}

这种方式导入数据到Excel,速度非常慢,有待下回介绍其他的方式.
