Question

我必须在excel文件中写一个字典（Key，value pair）。我尝试过使用Interop.Excel，并且写得像这样：

try
{
    string file =@”D:\Someexcel.xls”
    Interop.Excel.Application excelApp = new Interop.Excel.Application();
    excelApp.Visible = true;
    Interop.Excel.Workbook wb = excelApp.Workbooks.Open(file, Type.Missing, Type.Missing,
        Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
        Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
        Type.Missing, Type.Missing);
    Interop.Excel.Worksheet ws = wb.ActiveSheet as Interop.Excel.Worksheet;
    Interop.Excel.Range rng = ws.get_Range("A1", Type.Missing);

    //Write Key, Value as header
    ws.Cells[1, 1] = "Key";
    ws.Cells[1, 2] = “Value”;

    int row = 2; // Initialize for keys.
    foreach (string key in dict.Keys)
    {
        int column = 1; // Initialize for values in key.
        ws.Cells[row, column] = key;
        column++;
        ws.Cells[row, column] = dict[key];
        row++;
    }

    if (ws != null)
        Marshal.ReleaseComObject(ws);
    if (wb != null)
        Marshal.ReleaseComObject(wb);
    if (excelApp != null)
        Marshal.ReleaseComObject(excelApp);
    DialogResult result = MessageBox.Show(string.Format("Excel file created , you can find the file @" + file));
    if (result == DialogResult.OK)
        this.Close();
}
catch (Exception err)
{
    string msg;
    msg = "Error:";
    msg = string.Concat(msg, err.Message);
    msg = string.Concat(msg, "Line:");
    msg = string.Concat(msg, err.Source);
    MessageBox.Show(msg);
}

但是，这段代码似乎更频繁地破解，然后没有说excel文件在服务器位置上已损坏。所以，我想试试OLEDB。我是OLEDB的新手。在互联网上随处搜索，但没有信息如何写字典。你能用Insert命令帮助我吗？

选中此示例以写入excel。

OLEDB类似于您的ADO.NET SqlDataAdapter，您可以在其中指定INSERT和UPDATE命令并使用DataTable来插入或更新。对于字典，您可以执行类似的操作，将Key，Value作为DataColumns并将条目添加为行没有'检查过但你也可以执行OledbCommand作为INSERT和UPDATE并执行非查询。希望这会有所帮助。
