Winform中gridview控件导出 excel(转)

本文介绍了一个使用C#实现将DataGridView中的数据导出到Excel文件的方法,并展示了如何连接数据库并填充DataGridView。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace Ex16_49
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        SqlConnection sqlcon = new SqlConnection("Data Source=(local);Database=db_16;Uid=sa;Pwd=");
        SqlDataAdapter myda;
        DataSet myds;

        private void Form1_Load(object sender, EventArgs e)
        {
            myda = new SqlDataAdapter("select * from tb_43_44", sqlcon);
            myds = new DataSet();
            sqlcon.Open();
            myda.Fill(myds);
            sqlcon.Close();
            dataGridView1.DataSource = myds.Tables[0];
        }

        private void button1_Click(object sender, EventArgs e)
        {
            ExportDataGridview(dataGridView1, true);
        }

        public bool ExportDataGridview(DataGridView dgv, bool isShowExcle)
        {
            if (dgv.Rows.Count == 0)
                return false;
            //建立Excel对象
            Excel.Application excel = new 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();
                    }
                }
            }
            return true;
        }
    }
}
