Question

我正在努力将Excel文件导入我的DataGridView。但是，如何导入DataGridView中具有选定行和列的excel文件？我只有将整个excel文件加载到DataGridView的代码，这是C＃的新手

我打开对话框文件并搜索excel文件，假设我的数据以C:34,D:34和E:34的一列或包含EmploayeeName的数据开头，然后选择前24行并将其加载到我的DataGridView。

在此先感谢您的帮助！这是我唯一的东西：（

private void OpenFile_Click(object sender, EventArgs e)
{
    OpenFileDialog fdlg = new OpenFileDialog();
    fdlg.Title = "Select file";
    fdlg.InitialDirectory = @"c:\";
    fdlg.FileName = txtFileName.Text;
    fdlg.Filter = "Excel Sheet(*.xlsx)|*.xlsx|All Files(*.*)|*.*";
    fdlg.FilterIndex = 1;
    fdlg.RestoreDirectory = true;
    if (fdlg.ShowDialog() == DialogResult.OK)
    {
        path = textBox1.Text;
        txtFileName.Text = fdlg.FileName;

        Application.DoEvents();
    }
}

private void LoadExcel_Click(object sender, EventArgs e)
{
    System.Data.OleDb.OleDbConnection MyConnection;
    System.Data.DataSet DtSet;
    System.Data.OleDb.OleDbDataAdapter MyCommand;
    MyConnection = new System.Data.OleDb.OleDbConnection(@"provider=Microsoft.Jet.OLEDB.4.0;Data Source='c:\csharp.net-informations.xls';Extended Properties=Excel 8.0;");
    MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", MyConnection);
    MyCommand.TableMappings.Add("Table", "Net-informations.com");
    DtSet = new System.Data.DataSet();
    MyCommand.Fill(DtSet);
    dgrdReciver.DataSource = DtSet.Tables[0];
    MyConnection.Close();
}
