我不能导入excel到datagridview

我只是试图从Excel中获取数据，并在excel中显示它们。当我单击button时，excel中的数据将在datagridview中列出。

我的代码：

private void btn_load_Click(object sender, EventArgs e) { try { System.Data.OleDb.OleDbConnection MyConnection; System.Data.DataSet DtSet; System.Data.OleDb.OleDbDataAdapter MyCommand; MyConnection = new System.Data.OleDb.OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source='C:\Users\Dell\Desktop\kitap.xlsx';Extended Properties='Excel 12.0;HDR=Yes;IMEX=1'"); MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", MyConnection); MyCommand.TableMappings.Add("Table", "TestTable"); DtSet = new System.Data.DataSet(); MyCommand.Fill(DtSet); dataGridView1.DataSource = DtSet.Tables[0]; MyConnection.Close(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } 

错误：

Answer 1

尝试这个

 private void button1_Click(object sender, EventArgs e) { String name = "sheet1"; String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + "C:\\Sample.xlsx" + ";Extended Properties='Excel 12.0 XML;HDR=YES;';"; OleDbConnection con = new OleDbConnection(constr); OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con); con.Open(); OleDbDataAdapter sda = new OleDbDataAdapter(oconn); DataTable data = new DataTable(); sda.Fill(data); grid_items.DataSource = data; }
