篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了将excel数据导入到datagridview中相关的知识,希望对你有一定的参考价值。
datagridview表头我已经在winfrom中设置好了,然后exce的第一行为了填写数据方便依然写的有表头。
constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filepath + ";Extended Properties='Excel 8.0;HDR=NO;IMEX=1'";
导入后表头依然有呀,如上图。应该如何设置呀
借助于SQL。代码如下:
using System;using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.IO;
//using Microsoft.Office.Interop.Excel;
using System.Data.OleDb;
using System.ComponentModel;
using System.Data;
using System.Drawing;
namespace ClothingSales_0._5
public class Import
//private string fileName;
/// <summary>
/// 将DataGridView中数据导入到Excel
/// </summary>
/// <param name="dgv">DataGridView的名称</param>
public bool getExcel(DataGridView dgv,Label lbl)
bool fflag = true;
OpenFileDialog open = new OpenFileDialog();
open.Title = "请选择要导入的Excel文件";
open.Filter = "Excel文件(*.xls)|*.xls";
if (open.ShowDialog() == DialogResult.OK)
string fileName = open.FileName;
//根据路径打开一个Excel文件并将数据填充到DataSet中
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = " + fileName + ";Extended Properties ='Excel 8.0;HDR=NO;IMEX=1'";//导入时包含Excel中的第一行数据,并且将数字和字符混合的单元格视为文本进行导入
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
string strExcel = "select * from [sheet1$]";
OleDbDataAdapter comm = new OleDbDataAdapter(strExcel, strConn);
DataSet ds = new DataSet();
try
comm.Fill(ds, "table1");
catch
MessageBox.Show("错误信息:009", "错误");
comm.Fill(ds, "table1");
//根据DataGridView的列构造一个新的DataTable
DataTable dt = new DataTable();
DataTable dt2 = new DataTable();
foreach (DataGridViewColumn dgvc in dgv.Columns)
if (dgvc.Visible)
DataColumn dc = new DataColumn();
dc.ColumnName = dgvc.DataPropertyName;
dt.Columns.Add(dc);
DataColumn dc2 = new DataColumn();
dc2.ColumnName = dgvc.DataPropertyName;
dt2.Columns.Add(dc2);
if (dgvc.CellType == typeof(DataGridViewCheckBoxCell))
dc2.DataType = Type.GetType("System.Boolean");
//根据Excel的行逐一对上面构造的DataTable的列进行赋值
foreach (DataRow excelRow in ds.Tables[0].Rows)
int i = 0;
DataRow dr = dt.NewRow();
foreach (DataColumn dc in dt.Columns)
dr[dc] = excelRow[i];
i++;
dt.Rows.Add(dr);
//判断Excel的格式是否正确
int n = 0;
for (int j = 0; j < dt.Columns.Count; j++)
bool flag = false;
for (int k = n; k < dgv.ColumnCount; k++)
if (dgv.Columns[k].Visible) //隐藏的列
if (dgv.Columns[k].HeaderText.Trim().ToString() == dt.Rows[0][j].ToString())
if (dgv.Columns[k].CellType == typeof(DataGridViewCheckBoxCell))
//list.Add(j);
//num++;
flag = true;
n = k + 1;
break;
if (flag == false)
MessageBox.Show("导入的Excel的格式错误", "提示");
fflag = false;
return fflag;
//删除多余的行
int rowCount = (dt.Rows.Count) / 2;
for (int i = 0; i <= rowCount; i++)
dt.Rows.RemoveAt(0);
//处理Boolean类型的数据
for (int i = 0; i < dt.Rows.Count; i++)
DataRow dr = dt2.NewRow();
for (int j = 0; j < dt.Columns.Count; j++)
try
dr[j] = dt.Rows[i][j];
catch
dr[j] = false;
dt2.Rows.Add(dr);
//导入到dataGridView
dgv.DataSource = dt2;
lbl.Text = dgv.RowCount.ToString();
else
fflag = false;
return fflag;
参考技术A 给你个方法 你调用就可以了
public DataTable ExcelToDataTable(string pathName, string sheetName)
DataTable tbContainer = new DataTable();
string strConn = string.Empty;
try
FileInfo file = new FileInfo(pathName);
if (!file.Exists)
throw new Exception("文件不存在");
string extension = file.Extension;
switch (extension)
case ".xls":
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathName + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
break;
case ".xlsx":
strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pathName + ";Extended Properties='Excel 12.0;HDR=Yes;IMEX=1;'";
break;
default:
strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathName + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
break;
OleDbConnection connxls = new OleDbConnection(strConn);
connxls.Open();
DataTable dtExcelSchema = connxls.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] null, null, null, "TABLE" );
string sheetname = dtExcelSchema.Rows[0]["TABLE_NAME"].ToString();//获取表名
connxls.Close();
OleDbDataAdapter oda = new OleDbDataAdapter(string.Format("select * from [0]", sheetname), connxls);
DataSet ds = new DataSet();
oda.Fill(tbContainer);
return tbContainer;
catch (Exception ex)
MessageBox.Show(ex.ToString());
return tbContainer;
本回答被提问者和网友采纳 参考技术B 你是要连EXCEL的表头一起导入吗?追问
表头我已经在程序里面设置好了。只是在excel里面第一行还是表头。我想导入excel数据到datagridview,如果我把程序里面写好的datagridview的表头都删除是个空的datagridview刚好导入成功。现在我在表头我已经在程序里面设置好了。需要怎么设置才能呢
