我想将 Excel 文件的特定单元格导入 datagridview 的特定单元格。

我在这里遵循了许多导入 Excel 表格的教程，但由于我只需要 datagridview 特定位置的特定单元格，因此我调整了代码。

而不是：DataGridView1.DataSource = dt;我做了：dataGridView1.Rows[0].Cells[0].Value = dt;但它不起作用。

任何人都可以帮助我吗？

谢谢

这是代码：

string constr = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + textBox1.Text + @";Extended Properties=""Excel 12.0 Macro;HDR=YES;ImportMixedTypes=Text;TypeGuessRows=0""";

        OleDbConnection con = new OleDbConnection(constr);

        //specific cell 1 - product "code"
        OleDbDataAdapter sda = new OleDbDataAdapter("Select * From [ARTIGOS$A" + textBox3.Text + ":A" + textBox3.Text + "]", con);
        //specific cell 2 - product "description"
        OleDbDataAdapter sdb = new OleDbDataAdapter("select * From [ARTIGOS$B" + textBox3.Text + ":B" + textBox3.Text + "]", con);
        //specific cell 3 - product "price"
        OleDbDataAdapter sdc = new OleDbDataAdapter("Select * From [ARTIGOS$I" + textBox3.Text + ":I" + textBox3.Text + "]", con);

        DataTable dt = new DataTable();
        DataTable dt2 = new DataTable();
        DataTable dt3 = new DataTable();

        sda.Fill(dt);
        sdb.Fill(dt2);
        sdc.Fill(dt3);

        dataGridView1.Rows.Add();
        dataGridView1.Rows[0].Cells[0].Value = dt;
        dataGridView1.Rows[0].Cells[1].Value = dt2;
        dataGridView1.Rows.Add();
        dataGridView1.Rows[0].Cells[2].Value = textBox2.Text;
        dataGridView1.Rows[0].Cells[3].Value = dt3;

参考以下代码：

private Excel.Application App;
private Excel.Range rng = null;
private void button1_Click_1(object sender, EventArgs e) {
    OpenFileDialog OFD = new OpenFileDialog();
    OFD.Filter = "Excel Worksheets|*.xls;*.xlsx;*.xlsm;*.csv";
    if (OFD.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
        App = new Excel.Application();
        App.Visible = true;
        App.Workbooks.Open(OFD.FileName);
    }
    else { return; }

    try { rng = (Excel.Range)App.InputBox("Please select a range", "Range Selection", Type: 8); }
    catch {  } // user pressed cancel on input box

    if (rng != null) { 
        DataTable dt = ConvertRangeToDataTable();
        if (dt != null) { dataGridView1.DataSource = dt; }
    }
    _Dispose();
}
private DataTable ConvertRangeToDataTable() {
    try {
        DataTable dt = new DataTable();
        int ColCount = rng.Columns.Count;
        int RowCount = rng.Rows.Count;

        for (int i = 0; i < ColCount; i++) {
            DataColumn dc = new DataColumn();
            dt.Columns.Add(dc);
        }
        for (int i = 1; i <= RowCount; i++) {
            DataRow dr = dt.NewRow();
            for (int j = 1; j <= ColCount; j++) { dr[j - 1] = rng.Cells[i, j].Value2; }
            dt.Rows.Add(dr);
        }
        return dt;
    }
    catch { return null; }
}
private void _Dispose() {
    try { Marshal.ReleaseComObject(rng); }
    catch { }
    finally { rng = null; }
    try { App.Quit(); Marshal.ReleaseComObject(App); }
    catch { }
    finally { App = null; }
}
